SwRI Information

Home

A number of high-pressure, high-temperature autoclaves with the ability to monitor electrochemical conditions are housed in a special facility at Southwest Research Institute (SwRI).

Autoclaves

Autoclave capabilities include stirring and pressure ratings up to 20,000 psi at 650 °F. Constant and cyclic loading test frames as well as 10 slow strain rate (SSR) systems are used for stress corrosion cracking studies. The SSR systems include capabilities for testing at ambient temperature and pressure and in high-pressure, high-temperature environments. The rated pressure and temperature of the autoclave vessels employed for SSR work are 2,000 psi and 450 °F.

 

Specialized Test Facilities

SwRI has experience designing, constructing and operating specialized test facilities to meet specific client needs. Our staff members have many years of experience with full-scale testing, high-temperature high-pressure tests, and testing in hazardous environments such as those containing H2S and CO2.

 

SwRI offers a new facility equipped to conduct full-scale testing in hazardous conditions including H2S and high-pressure, high-temperature environments. The facility is currently configured to qualify the use of a composite choke and kill line (part of the subsea blowout preventer stack) used for high-temperature and high-pressure applications. Tests are conducted in accordance with API 16C specification at 70 MPa at 150 °C using a NaCl brine and hydrocarbon equilibrated with a H2S/CO2/CH4 gas mixture.
