Ring joint gasket

These Gaskets are manufactured in different solid metal types like soft iron/SS304/316/321 metal and other alloy items.
They are used to stand high pressure and temperatures and they are employed where corrosive agents are present.
These gaskets are obtained by mechanical working from forged or laminated metals.
They are employed in the production and refining process of oil and chemical industries.
These gaskets are designed in oval/octagonal shapes confirming to R,Bx and Rx series of API std 6A.

Oval ring joint
These rings are manufactured in accordance with JPI-7S23, ANSI B16.20 and API 6A used on the ring type joint flanges specified in JPI-7S-15, ANSI B16.5, API spec 6A and MSS sp-44
Octagonal ring joint

GOT-450 Ring Joint Gasket chooses solid metal with kinds of materials, and is mechanically cut and processed into metal sealing gaskets with kinds of forms by high precision NC lathe. It is suitable for the sealing part of pressure container, valve, and cylinder head with high temperature, high pressure, and strong corrosion. General characteristic is installation area small and preload pressure high.
