Safety Valve Testing

Go to Safety Valve Testing


The Flow Component Testing Facilities (FCTF) at SwRI are accredited through the American Petroleum Institute (API) to perform validation testing on both surface and subsurface safety valves. The facilities are also used to perform testing on other downhole safety valves, riser isolation valves, and wellhead valves.  All testing is completed under an API Q1 and ISO 17025 quality management system.

API 14A – Subsurface Safety Valves (SSSV)

SwRI performs SSSV testing on surface control safety valves (SCSSV) and subsurface control safety valves (SSCSV), subsurface injection safety valves (SSISV), and annular safety valves.

  • Validation Testing – Annex B
  • Functional Testing – Annex C
  • Operating Life Testing, Differential Opening – Annex G
  • Extended Sand Endurance Testing – Annex I
  • High Rate Gas Slam Closure Testing – Annex K
  • Experimental Flow and Integrity Testing

API 6AV1 – Wellhead Surface Safety Valves and Underwater Safety Valve for Offshore Service  

SwRI performs testing on various types of valves used as underwater safety valves (USV), surface safety valves (SSV), and boarding shutdown valves (BDSV).  This equipment is essential for emergency shutdown of offshore production.

Sand Service Validation Testing is performed per Class II or Class III per the latest revision of API 6AV1.  Similar experimental testing is also performed per client-specific testing procedures.
