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.KXT-G1810 ring joint gasket octagonal type is also called
RTJ octagonal type. Similar to KXT-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.
Note：
The material of the oval ring jont gasket must be
15~20HB lower than the hardness of flange,and this kind of gaskets is
non-recyclable.
