Xpandable Patch High Temp

Saltel Xpandable Patch High Temp

Xpandable Steel Hi Temp PatchSaltel Industries have developped and qualified a new range of products available under 200°C/392°F working conditions, from 4-1/2 in to 13-3/8 in casing sizes.
Saltel High Temp Patch is a permanent solution used to repair a zone of damaged tubing or casing, to shut-off unwanted peforations, to seal a leaking sliding sleeve, or other remedial operations. This expandable short length of tubular is made from high quality stainless steel with an elastomer outer skin and a profiled sealing system. Saltel HT Patch is run on tubing or drill pipe. At depth the patch is expanded using a high pressure inflatable element, and pushed against the casing to activate the outer seals. The setting tools are then extracted, to leave a pressure resistant inner lining inside the well

Setting temperature limited to 150°C (300°F). 

Saltel High Temp Patch is based on the Standard design modified to use high temperature elastomer. The extremities are covered with a mix of Fluoroelastomers FEPM and FKM.
