HOW CAN WE HELP YOU?

Fugitive emissions testing of valves, flanges, and other products is an area that SwRI is actively involved with in the refining industry. Tests can be performed from cryogenic temperatures of -320°F (liquid nitrogen submersion) to temperatures higher than 750°F.  All testing is performed under a quality/safety system with qualified operators.

Fugitive emissions testing consists of measuring emissions to the atmosphere at maximum operating conditions of the product (temperature and pressure). This is performed using either helium or methane gas depending on the test procedure, each of which have their respective limitations.
