Oval Ring Joint Gasket
WL-G1800
Description
Oval ring joint gasket is machined from solid metals in a variety of shapes. They are designed for high pressure, high temperature or highly corrosive applications. These basic shapes are used in pressures up to 10,000 psi. The dimensions are standardized and require specially grooved flanges. It is made of the most suitable material and shapes.
WL-G1800 ring joint gasket oval type is also called RTJ oval type. It is mechanically made from integral metal include soft iron, SS304, SS316, carbon steel, SS321. It 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 petro chemistry.

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.
