CUI - Preformed End Cap Gasket

Product information

The end cap termination of pipe insulation is a critical point of water proofing for the pipe insulation system. Keeping water out is the first line of defense against corrosion under insulation (CUI). Water ingress and wet-insulation is the primary underlying factor which allows CUI to occur over time.

Using the traditional stainless steel terminations a number of problems may occur during the installation phase: Cutting injuries, damaged heat trace cables, scratches and damages on the pipe’s paint systems (even insulators drilling holes in the pipes), and great prefab difficulties when it comes to the fabrication of metallic end caps for slim insulation systems (i.e. aerogels). Traditional metallic end caps are often also not completely watertight.

By using an easy to install gasket which does not require any modifications to fit, large amounts of installation time is saved, and the risk of damaging the coating system and the heat trace of the pipe during installation is mitigated. This is the termination solution offered by the use of Benarx Preformed End Cap Gaskets. In addition, a non-metallic solution with better water sealing properties will help to save future maintenance costs and failures caused by CUI.

The product is offered in two different versions: Cutted (flat) end caps and molded (sloped) end caps.

Benarx Preformed End Cap Gaskets can be used for termination of any thermal or ccoustic Insulation system. The product also helps to mitigate CUI.

CNC-cutted end caps (flat, blue) can be used on pipe operating temperatures up to 230’C

Molded end caps (sloped, black) can be used on pipe operating temperature up to 270’C
