Seal-Tite have successfully repaired over 1000 subsurface safety valve systems in both subsea and on dry tree applications. Wellheads seals such as casing and tubing hangers have been repaired over 1500 times.
Pressure activated sealants only polymerise at the leak site on differential pressure forming a flexible solid repair. The remainder of the sealant is the system remains liquid. This means the SCSSV system can use the unpolymerised sealant as part of the hydraulic control system and wellhead systems can be pressure tested after the repair.
Applicable in Subsea and Dry Tree environments
