Octagonal Ring Joint Gasket

WL-G1810

 

Description

Octagonal ring joint gasket is machined from solid metals in a variety of shapes. Octagonal ring joint gasket are designed for high pressure, high temperature or highly corrosive applications.WL-G1810 ring joint gasket octagonal type is also called RTJ octagonal type. Similar to WL-G1800, Ring Joint Gasket octagonal type is made from solid metal, but becomes octagonal shape. It is mechanically made from integral metal. The available materials include soft iron, SS304, SS316, carbon steel, SS321.

 

Application

Octagonal ring joint gasket is mainly used in the joint part of high-temperature, high-pressure pipeline, tower, groove and heat exchanger, suitable for steam industry, petroleum industry and petrochemistry.
