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.

Warning: Gasket materials should never be recommended when both the temperature and the pressure are at the maximums listed. Properties and applications shown are typical. No application should be undertaken by anyone without independent study and evaluation for suitability. Never use more than one gasket in one flange joint, and never reuse a gasket. Improper use or gasket selection could cause property damage and/or serious personal injury. The data reported is a compilation of field testing, field service reports and/or in-house testing.
