Valve Integrity, Fugitive Emission & Cryogenic Testing

Testing the pressure integrity and sealing ability of valves is critical for industrial applications. If these potential leak points are not identified, operators can experience lost inventory, fines for broken regulations, safety hazards, and negative environmental impacts. Validating the pressure and sealing integrity of valves prior to installation will significantly reduce these risks. SwRI provides standardized valve integrity, fugitive emission, and cryogenic testing to qualify valves based on industry-accepted leak rates for external and internal sealing elements.

Valve Integrity Qualification Testing for the Oil, Natural Gas, Power Generation, and Petrochemical Industries

Valve integrity testing can be performed with liquid or gas, at pressures up to 35,000 psig, and valve sizes from ¼ inch to >24 inch. SwRI’s valve test capabilities include the following standardized test procedures:

  • MSS-SP-61 – Pressure Testing of Valves
  • API 598 – Valve Inspection and Testing
  • ANSI FCI 70-2 – Control Valve Seat Leakage
  • ISO 5208 – Industrial Valves - Pressure Testing of Metallic Valves
  • Custom test procedures can be accommodated based on the project requirements

A fugitive emission test is performed using either helium or methane gas depending on the test procedure, each of which has its respective limitations. It measures emissions to the atmosphere at maximum operating conditions of the product (temperature and pressure). Southwest Research Institute is actively involved in fugitive emissions testing across the oil and gas industry.

Fugitive emission test procedures for valves, flanges, and other products are governed by several industry standards. Tests can be performed from cryogenic temperatures of -320°F (liquid nitrogen submersion) to temperatures higher than 800°F. All fugitive emissions testing is performed under a quality/safety system with qualified operators.

Fugitive Emission Test for Control Valves & Isolation Valves

SwRI provides standard and custom fugitive emission tests for control valves from cryogenic temperatures of -320ᵒF to temperatures greater than 800ᵒF, including:

  • ISO 15848-1– Measurement, Test, and Qualification Procedures for Fugitive Emissions, Classification System, and Qualification Procedures for Type Testing of Valves
  • ISO 15848-2 – Measurement, Test, and Qualification Procedures for Fugitive Emissions, Production Acceptance Test of Valves
  • MESC SPE 77/300 – Procedure and Technical Specification for Type Acceptance Testing (TAT) of Industrial Valves
  • MESC SPE 77/312 – Fugitive Emission Production Testing (Amendments/Supplements to ISO 15848-2)
  • API 624 - Type Testing of Rising Stem Valves Equipped with Graphite Packing for Fugitive Emissions
  • API 641 - Type Testing of Quarter-turn Valves for Fugitive Emissions
  • Custom test procedures can be accommodated based on the project requirements

Cryogenic Test for Valves

Performing a cryogenic test for valves and other products used in the oil and gas industry may entail full immersion in liquid nitrogen immersion (-320°F). SwRI performs cryogenic testing to meet standardized tests or design and fabricate custom test chambers, including:

  • BS 6364 – Specification for Valves for Cryogenic Service
