Garlock: Streamlining Quality Assurance in Expansion Joint Manufacturing

Ensuring the reliability and performance of expansion joints is paramount in various industrial applications. Garlock’s approach to in-house validation testing offers significant advantages over traditional third-party testing methods.

The Importance of In-House Validation Testing

In-house testing capabilities allow manufacturers to:

• Reduce Lead Times: Immediate access to test results accelerates the design and development process.
• Cut Costs: Eliminates expenses associated with third-party testing, leading to more competitive pricing.
• Enhance Customization: Tailor tests to simulate real-world conditions, providing more accurate performance data.

Key In-House Tests for Expansion Joints

Garlock employs several critical tests to ensure the quality and performance of their expansion joints:

1. Burst Test

This test involves pressurizing an expansion joint until failure occurs, simulating pressure surges in piping systems. Achieving a safety factor rating higher than the industry standard of 3:1 demonstrates superior reliability.

2. Spring Rate Test

Measuring the force required to compress or elongate an expansion joint, this test assesses its flexibility and responsiveness under various conditions.

3. Vacuum Test

A modified vacuum test simulates the effects of negative pressure on the joint, ensuring it maintains integrity under extreme conditions.

4. Movement Test

Simulating real-world movement and pressure scenarios, this test evaluates the joint’s performance under dynamic conditions.

Benefits of Garlock’s Approach

By conducting these tests in-house, Garlock ensures:

• Accurate and Timely Results: Faster turnaround times facilitate quicker decision-making.
• Comprehensive Data: Detailed test data supports continuous improvement and innovation.
• Cost Efficiency: Savings from reduced third-party testing can be reinvested into product development.
