Score Valve Services Inc. - Testing
In the industries we service, the consequences of leaking valves are likely to be severe; therefore product pressure testing is a critical part of ensuring product integrity. Every customer wants the reassurance that the valves being commissioned on their site have been comprehensively pressure tested. At Score Valve Services Inc. we conduct pressure testing using purpose-built facilities, fully trained personnel and proven procedures to provide you with the confidence that the products supplied are going to perform to your expectations.
Score Valve Services Inc. have modern specialist facilities for:
- Hydrostatic Testing
Valves of a variety of types and sizes are tested within our test cells at prescribed pressures using different fluids, including inhibited water, in accordance with international standards such as, API 6D and API 598. This procedure, which is often the last of a series of tests undertaken before final coating, verifies the strengths of critical valve components including body, bonnet, ends and seats. Hydrostatic testing also investigates the integrity of the valve’s pressure retention envelope and seat sealing capability when subjected to internal pressures greatly in excess of those likely to be encountered during a normal operational life span. Leakage can be identified using a pressure gauge, or recorded automatically with a chart reader device which monitors pressure loss over time. Testing procedures are viewed by camera and these together with results obtained are open to any inspection by customers and independent third parties.
- High Pressure Gas Testing
Utilising high-pressure pumping systems, valves and other components can be tested underwater at internal gas pressures of up to 30,000psi. Any leakage, however small, is detected and measured by fully calibrated gas flow meters.
- External Leak Detection
A variety of valves of different sizes and types can be tested with tracer gases including helium, or a mix of 99% nitrogen and 1% helium. External leakages can be detected or pinpointed using a mass spectrometer. Emissions testing can be carried out in accordance with international standards such as ISO 15848.
