Details

HPG insulation System is a high reliability system used for both isolating and general sealing purposes, especially suitable in High Pressure services including  ANSI 2500# and API 15,000# classes.


Description

Applications:

Flange isolation in conjunction with cathodic protection.

Isolation between dissimilar metals to prevent galvanic corrosion.

Wellhead isolation from inter-connected flow lines.

Mating mismatched ring-joint to raised-face flanges (HPG will seal in ring-joint, raised-face and flat face/slip-on flanges).

Eliminate fluid trap corrosion between ring-joint (RTJ) flanges where high concentrations of CO2, H2S and other aggressive hydrocarbon media are present.

Eliminate turbulence and flow-induced erosion between ring-joint (RTJ) flanges.

Protect against coating damage on coated flange faces.

To seal between flanges subjected to vibration/cavitation.
