      • Scraper valve Type HM

      • HARTMANN VALVES pigging ball valves of the HM series combine the advantages of the HARTMANN VALVES AST series, and in addition to classic applications function as shut-off valves for pigging insertion or removal valves. The simple, secure, and fast insertion and removal of pigs takes place through an interlock that is integrated on the side of the pigging ball valve and that is locked and secured through a bayonet system.
        HARTMANN VALVES pigging ball valve can be obtained as a scraper valve for cleaning operations (type HMR), as a scraper valve for cleaning operations, but in addition with a bypass in the closed position for applications during which the medium flow is not to be interrupted completely (type HMB)), and as a scraper valve for separating different products in a pipe line (type HMS).

        In the standard version HARTMANN VALVES pigging ball valves are designed for a maximum pig length of 1.4 x nominal diameter of the pipe line. Upon request, we are pleased to offer you special constructions for spherical pigs or cylindrical pigs longer than 1.1 to 1.4 x diameter up to a maximum of 2.0 x diameter.

        The simple handling of the HARTMANN VALVES pigging ball valves speaks for itself: For the insertion or removal of the pig the ball is rotated by 90°, meaning it is rotated into the closed position. Prior to the opening of the interlock the housing interior is depressurized via a release valve, then the bayonet catch is unlocked and opened with a left turn. The pig can now be inserted or removed through the interlock.
        The advantages of the HARTMANN VALVES ball valves are primarily: Simpler operation, secure handing, reduced footprint, lower investment costs in comparison to traditional pigging interlocks.

      • Industries

      • Challenging Applications – We support our customers with industry specific expertise, innovative solution concepts and reliable products.
          • OIL / GAS EXTRACTION

          • Harsh operating conditions and aggressive media call for especially durable wellhead equipment and reliable shut-off valves.
              • DEMANDING MEDIA

              • Hartmann wellheads with integrated ball valves are distinguished by their special robustness and long service life.

                In the extraction of oil and gas a multitude of particles and concomitant materials are entrained in the medium flow. This places high demands on the shut-off valves.
                For more than 70 years Hartmann products, with their robust and individually tailored design, have provided the highest level of safety – even with dangerous and corrosive media such as sour gas, sour oil (H2S) and CO2.
                An experienced service team is available around the clock for assembly service, repairs and maintenance work.

              • RELIABLE COMBINATION

              • In both conventional wellhead design and in solid block design, metal-to-metal sealing ball valves provide the highest level of safety.

                Wellheads with gas-tight ball valves have proven themselves to be very successful on the market.

                Our API 6A conformant wellheads are fitted as standard with metal-to-metal sealing ball valves which are also gas-tight. In comparison to gate valves they offer a very high level of safety as they have a lower tendency towards blocking, are subject to less wear and don’t have to be filled with grease which can contaminate downstream plant parts. Thanks to the metallic sealing between ball and seat ring, Hartmann ball valves fulfil a leak rate of A or 0 and are especially robust and require only little maintenance. Additional safety is provided by a second barrier (DIB 2). Decisive for the long service life is an appropriate material selection as well as surface treatments and special coatings – against corrosion, for example.

                Hartmann wellheads are adapted to individual customer requirements as conventional or integrated designs.

              • INTEGRATED DESIGN AND SPECIAL SOLUTIONS

              • This wellhead for sour gas production is equipped with a quick-closing valve with the appropriate actuator.

                With the integral design the functions of several valves and wellhead components are brought together in one component. By this means, not only is the installed height minimised but by saving on flanged connections, safety is increased above all. Added to that, the installation time is reduced, corrosion-prone nuts and bolts are dispensed with and an absolutely perpendicular installation with uninterrupted diameter is a given.
                In the area of oil extraction, Hartmann ball valves are also suitable at high temperatures in the steam applications used to fluidise the oil. In this regard the viscosity is lowered by steam injection at high temperatures.

              • PIG VALVES

              • Scrapers lend themselves to the cleaning of paraffin deposits or water condensate. Hartmann pig valves offer a space and cost saving alternative to complex pig launching stations. In addition to the conventional application as a shut-off valve, the pigging valve functions as a sending or receiving valve for pigs.The pig valve can furthermore be deployed for separating various products in a pipeline. This concept has two independent safety barriers when opening and requires no special tools. Hartmann pigging valves are deployed, amongst others, by well-known oil concerns as a global standard solution.
            • STORAGE TECHNOLOGY

            • Hartmann wellheads and valves with their gas-tight components and their long service lives are ideally suited for the equipping of underground storages.
                • SAFE STORAGE OF CRUDE OIL AND NATURAL GAS

                • As a system supplier to the storage industry, Hartmann is involved in virtually all German oil and gas storage projects.

                  As early as the 70’s the underground storage capacity in Germany was massively extended for the national oil reserves. In oil storage, oil and saturated salt solution (brine) are alternated. With its high salt content, the brine is very corrosive and thus places high demands on wellhead materials.
                  Akin to crude oil storage, gas is also stored in subterranean reservoirs. These can be previously depleted reservoirs, aquifers or artificially produced cavities (caverns). Gas storage serves fundamentally to compensate for the varying seasonal demands. Cavern reservoirs in particular have large access cross sections and are stringently reliant on gas-tight components. Due to these demands, Hartmann has been able to assert itself as market leader for the equipping of gas reservoirs. Originating in Germany, the wellheads are also being deployed in many international projects in England, Denmark, the Netherlands, Portugal, Turkey and China.
                  Hartmann ball valves are integrated into the wellheads as a reliable shut-off or are deployed as high-performance valves in brine plants, compressor stations and gas refinement plants.

                • RELIABLE COMBINATION

                • Hartmann wellheads with integrated ball valves are characterized by their special resistance and longevity.

                  Wellheads with gas-tight ball valves have proven to be very successful in the market.

                  In contrast to oil and gas extraction, storage necessitates considerably larger pipe cross sections. Conventional shut-off concepts such as gate valves are not up to these demands. Which is why our API 6A conformant wellheads are fitted as standard with metal-to-metal sealing ball valves which are also gas-tight. Compared to Gate Valves, they offer greater safety, as they are less prone to blocking, subject to less wear and need not be filled with grease, which could contaminate downstream equipment. Thanks to the purely metallic seal between ball and seat ring, the Hartmann ball valves fulfill a leak rate of A or 0 in all pressure stages and are particularly resistant and require little maintenance. Additional security is provided by a double barrier (DIB 2). Decisive for the long service life are an appropriate selection of materials as well as surface treatments and special coatings, for example against corrosion.

                  Adapted to individual customer requirements Wellheads are in classic design or available. In the latter case, the functions of several valves and wellhead components are combined in one component. This not only minimizes the height, but also increases safety by saving flange connections. In addition, the construction time is reduced, corrosion-prone bolts and nuts are eliminated and an absolutely vertical structure with undisturbed drift diameter is given.

                • EFFICIENCY BOOSTING OF EXISTING PLANTS

                • This x-mas treee in solid block design has the latest wellhead technology and offers increased safety due to the reduction of interfaces.

                  Many of the existing storage plants undergo a general overhaul after years of operation. The borehole completion is replaced and in the process, the wellheads are brought up to the latest state of technology. In collaboration with our customers we have, for example, been able to significantly increase the safety and integrity of the reservoirs in the past years. Hence strain gauges are used for monitoring the pipes and individual components are combined in blocks (block design) whereby interfaces are reduced. In addition to the metallic sealing he ball valves were also fitted with a second barrier (DIB 2). Remaining flange connections have also been given a second barrier and partial metallic sealing. With these innovative concepts, which the conventional oil and gas industries don’t offer, Hartmann Valves are making a sustainable contribution to long-term safety in reservoir storage. At the same time, professional consultation and support during all project phases are for us a given. The experienced Hartmann service team is available around the clock for installation and maintenance work.

                • STORAGE OF RENEWABLE ENERGIES AND SPECIAL MEDIA

                • In customized design Hartmann wellheads are available for the safe storage of large amounts of energy.

                  For the continued expansion of renewable energies a storage potential is necessary for enormously large quantities of energy. This energy can and is being stored in underground caverns. In this regard compressed air energy storage (CAES), with components from Hartmann, has been in existence for several decades and a further step (pilot projects have been or are already being implemented) is the storage of hydrogen and synthetic natural gas storage. In the area of hydrogen storage we are able to fall back on the many years of experience gathered from supplying to refineries all over the world. Flexibility and cross-industry experience has meant that the company Hartmann has also established itself as a good partner in the area of these special applications. Hence Hartmann has also equipped the first European storage cavern for helium.

              • CHEMICAL / PETROCHEMICAL

              • Tailor-made Hartmann valves provide safe shut-off in the high performance area
                  • BALL VALVES FOR EXTREME CONDITIONS

                  • This FDA compliant hydrogen ball valve has a metal-to-metal sealing and guarantees a leak rate of A or 0

                    The metal-to-metal sealing ball valves are designed to individual customer requirements and are distinguished by their long service life and low maintenance.

                    The generation of products in chemical processes presents high level demands on the reliability of the plant components. The areas of application of high performance valves are varied: designed to individual customer requirements they are suitable for temperatures of -200 to +550 °C, pressure stages up to 700 bar and up to 200,000 cycles per year. Hartmann valves are already in successful deployment for the following, in part aggressive media: crude oil, natural gas, acid gas, syngas, oxygen, hydrogen, helium, steam, thermal water, coal dust, slurry, slag & ashes, polymers, cellulose as well as abrasive and degreasing media.
                    The valves can be flexibly combined with electric, pneumatic or hydraulic actuator technology.

                  • MAXIMUM SAFETY AND DURABILITY

                  • The high leak-tightness and durability of the Hartmann special ball valves is achieved by means of a metallic sealing between ball and seat ring. This sealing system is gas-tight and also fulfils a leak rate of A or 0 even with high cycle operations. Even in the presence of contamination it is considerably more robust with low maintenance than soft sealing systems. A further decisive factor is the appropriate material selection as well as surface treatments and special coatings. Thanks to the longer maintenance intervals, substantial time and cost savings over the entire service life of a plant can be realised.
                    Additional safety is provided by special design features and safety orientated functions such as double isolation and bleed (DIB), two additional independent barriers or double block and bleed (DBB), which enable testing in the pipeline.
                    To increase the safety in existing plants with minimal outlay, the twin ball valve offers a compact and economical alternative to the deployment of multiple valves. These consist of two ball valves in one housing which can be equipped with two independent barriers if required.
                  • MULTI-WAY VALVES AND SPECIAL DESIGNS

                  • Multi-way valves lend themselves where switching over between different lines has to take place. An example of a typical application is the switching over between two filter systems. This makes continuous operation possible by which one filter remains in use while the second is cleaned, replaced or regenerated. The combination and mechanical coupling ensures that several valves are switched at precisely the same moment. The valves are furthermore used to switch over between different media, e.g. fuels on turbines. By means of the trunnion mounted design, the ball is centered in the middle of the valve even under asymmetric loads. The spring loaded sealing rings provide a reliable seal in all pressure situations. The different angle between the flanges and ball bores in L, T or X execution results in a variety of combinations.
                • GEOTHERMAL ENERGY

                • Decades-long expertise and durable wellheads make Hartmann Valves one of the sought-after partners in the field of deep geothermal energy.
                    • WELLHEADS WITH INTEGRATED BALL VALVES

                    • The use of metallic sealing ball valves on the wellheads ensures superior leak-tightness, a long service life and low maintenance requirements.

                      Our API 6A wellhead equipment guarantees safe borehole closure – even with demanding conditions and scaling formation.

                      More than 30 reference projects since 1978 speak for themselves: as interface between the borehole underground and the above-ground geothermal plants, Hartmann wellheads have been in maintenance-free deployment for years in the Munich Molasse basin, the Rhine graben as well as in France, Belgium, the Netherlands and Turkey, amongst others. Adapted to project-specific requirements and designed for the highest flow rates and temperatures, they provide maximum operational safety and plant availability.
                      The wellheads are, by default, fitted with gas-tight ball valves which have a metallic sealing between ball and seat ring thus guaranteeing extreme reliability and long service life. In contrast to gate valves, ball valves have the advantage that even with scaling deposits in the pipe they close securely and require significantly less maintenance. With high safety factor levels Hartmann ball valves are true workhorse valves which if required are provided with flushing connections, e.g. for acidification.

                    • ADAPTED GEOMETRY AND LONG-TERM PARTNERSHIP

                    • As a leading wellhead supplier in the German deep geothermal energy field, Hartmann Valves is assisting the Stadtwerke München (SWM) with the implementation of their district heating vision: by 2040 Munich will be the first large German city in which district heating will be extracted 100 % from renewable energies, above all geothermal. There are already two Hartmann wellheads being deployed in Freiham with six planned for the future in the Schäftlarnstraße which have been developed for the special project circumstances. Based on a framework contract, Hartmann Service is assisting with maintenance work such as the regular exchanging of pumps.
                      In Freiham the two boreholes have been drilled down to a true vertical depth (TVD) of approx. 2,500 metres. Producing around 90 litres per second at a temperature of 90 degrees Celsius, the district heating station is achieving a thermal capacity of up to 20 MW. The two boreholes were fitted with API 6A wellheads, pressure class 5000 psi and equipped with highly resistant metallic sealing ball valves. These have been prepared for retrofitting with an actuator where necessary. By means of the adapted design of an eccentric suspension for the 8 5/8 inch (approx. 220 mm) production casing string, enough space could be created for two cable penetrations for the pump. At the same time three further penetrations are made for the retrospective insertion of lines, e.g. for introducing inhibitors. The use of identical components in the production as well as the injection bores makes subsequent replacement between the two possible at any time, if necessary.
                  • RENEWABLE ENERGIES

                  • High performance valves for power to gas and wellheads for large-volume underground energy storage provide the highest levels of safety and set new standards.
                      • POWER TO GAS

                      • Innovative energy concept: deployment of hydrogen ball valves in the "WindGas Falkenhagen" power to gas plant.

                        For the safe storage of renewable energy in the natural gas network, gas-tight hydrogen ball valves by Hartmann Valves are deployed.

                        The power to gas process enables electrical power from regenerative energies to be made storable in the form of chemical energy. In various pilot plants wind energy, for example, is converted into hydrogen by means of electrolysis. Particularly high demands are placed on the shut-off valves by the medium hydrogen when feeding into the gas grid. Hartmann Valves, supplier of ball valves and wellheads for more than 70 years, has the appropriate expertise in the area of gas storage engineering and valves for extreme conditions, for example in hydrogen applications. Absolute gas-tight ball valves which have a pure metallic sealing system are already in use in several power to gas plants. Produced from high grade materials and designed for the special requirements of hydrogen, they guarantee extreme reliability and a long service life.

                      • ENERGY STORAGE IN CAVERNS

                      • With customer-specific designs, Hartmann wellheads are available for the safe storage of large quantities of energy.

                        Hartmann wellheads and valves provide the highest levels of safety with demanding media and innovative processes.

                        In order to store future large quantities of energy for balancing production and consumption, various concepts are being pursued. In so doing, different media such as compressed air energy storage (CAES), hydrogen or synthetic natural gas are stored underground.
                        Decades of experience from the crude oil, natural gas and chemical industries as well as collaboration in the first pilot projects makes Hartmann Valves a sought-after partner for the expansion of renewable energies and provides safe and controlled handling of the vast quantities of energy.

                        Based on the newest technical standards, adapted to the special requirements and in close coordination with the customers, the Hartmann wellheads are designed for this. Metal-to-metal sealing ball valves thereby guarantee a gas-tight and especially low maintenance shut-off.

                    • POWER PLANT TECHNOLOGY

                    • In power plants with particularly high demands, reliable high performance valves provide maximum safety.

                      Hartmann ball valves are deployed in many different power plants and thus also under the most varying conditions. Besides the applications listed below for hydropower, steam and gas turbines, ball valves for example are also being developed for the reverse transformation of electrical into chemically bonded energy in the form of hydrogen (see renewable energies).

                        • STEAM

                        • In the area of hydropower, potential energy derived from the height differential is transformed into electrical energy. Because these are open systems the water has a high oxygen and solids fraction which results in considerable corrosive and erosive loads. Due to the metallic sealing system and the careful selection of materials, Hartmann ball valves are ideally matched to these conditions.
                        • HYDROPOWER

                        • Steam turbines and the associated steam cycle are found in various types of power plants such as coal, nuclear or combined-cycle (GuD) plants. Steam, water and the intermediate form, saturated steam, place high demands on the material selection and design in terms of temperature and pressure loads. Even under these conditions the metal-to-metal sealing in combination with steam resistant seals has proven itself as a reliable system. With their experience of structural design for nuclear plants including earthquake calculations and the compilation of pre-test paperwork in the documentations department, Hartmann Valves is a reliable partner.
                        • GAS TURBINES

                        • With gas turbines, the safe infeed and, where applicable, shut-off is a deciding factor. Hartmann ball valves have proven themselves with their reliability in this area. Both standard ball valves and multi-way valves are deployed for operation with air, oil and gas. To increase the efficiency, the development is always towards higher input temperatures. Hartmann Valves is going down this route and offers special high temperature ball valves.

                            HIGH LEVEL OF FLEXIBILITY AND AVAILABILITY

                            With the new build of the storage plant in the Lower Saxony town of Jemgum, EWE Gasspeicher GmbH commissioned Hartmann Valves GmbH to supply all brine and gas wellheads, diverse special ball valves and the associated assembly and maintenance service. The „Hartmann concept“, i.e. the use of pure metallic sealing ball valves as wellhead shut-off valves which are absolutely gas-tight even in large nominal bores, had already proven itself in the equipping of other storage plants as highly durable and virtually maintenance-free.

                            Reliable isolation for Wolfersberg Gas Storage – Unique Twin Ball Valves designed for space limitation

                            Since the upper Bavarian gas storage facility of DEA was established in 1973 about 800 Hartmann ball valves have been installed in the various operations. The depleted gas reservoir with depths of 2,900 to 3,000 metre located southeast of Munich is the deepest gas storage in Europe. Besides the 10 wells for injection and production, facilities are run for the compression, pressure reduction, drying and temperature control of the gas. A very high safety level as well as plant availability are critical. When old shut-off valves had to be replaced, Hartmann designed extra compact Twin Ball Valves, which are bubble-tight and solve problems of space limitation.

                            Optimal planned maintenance of safety ball valves enables recommissioning on schedule

                            The natural gas field Völkersen located in the north-western part of Lower Saxony and operated by DEA is one of the most productive in Germany. When operating, as well as during service and preventative maintenance of the surface facilities and the production wells conducted by DEA Niedersachsen, safety has top priority. All components of the plant have to fulfill the highest technical requirements at any time.
                            In the course of regular 5 yearly maintenance of the Central Gas Drying Plant about 20 ball valves manufactured by Hartmann Valves were inspected and overhauled in September 2016. Thanks to early planning and close cooperation all valves could be reconditioned in a short period and taken back into operation right on schedule.
