Score (Canada) Limited - 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 the ensuring product integrity. Every customer wants the reassurance that the valves being commissioned on their site have been comprehensively pressure tested. At Score Canada Limited 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 (Canada) Limited have modern specialist facilities for:
- Hydrostatic Testing
Valves of a variety of types and sizes are tested in experimental pipelines within test cells at prescribed pressures using different fluids, including inhibited water, in accordance with API 6D and ISO 14313 specifications. This procedure, which is often the last of a series of tests undertaken before re-painting, 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 is measured on 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
Utilizing high-pressure pumping systems, valves and other components can be tested underwater in experimental pipelines at internal gas pressures of up to 30,000psi. Any leakage, however small, is detected and measured by fully calibrated micro manometers.
- External Leak Detection
A variety of valves of different sizes and types can be tested with tracer gases including methane or helium, or a mix of 99% nitrogen and 1% helium. Using our high-sensitivity mass spectrometer, external leakage rates as low as one billionth of a cubic centimetre per second can be detected and pinpointed.
