High Light: ASME B16.20 octagonal ring joint gasket, SS316 lens ring flange, SS316 flat o ring gasket

CNC machines, sawing machines, spectrograph, desktop hardness, laser marking machine, coating thickness gauge and other equipments.
We specializes in ring joint gasket, including ring gasket in R, RX, BX, IX types, lens gasket, weld ring gasket and bonnet gasket(according to client’s drawing). The metal gasket designed for use in high pressure, high temperature application necessitated the need for a high integrity seal. Our products are widely used in flat gate valve, Christmas tree, pipeline fittings, flange, high pressure vessel, oil &gas industry, wellhead assembly, petrochemical industry and the like.
We can offer more than 30 kinds of materials, such as 321SS, 347SS, 316SS, 304SS, Inconel 625, Monel 400, INCOLY 825, Nickel 200, Duplex F44, soft iron, low carbon steel and so on. We could produce the maximum outside diameter is 2500mm.

We Manufacture and supply high quality Ring joint Gaskets for high pressure and temperature service conditions. These gaskets are widely used in Refineries, Petrochemical Industries, Oil drilling well head equipments, Pressure Vessels, valves, Christmas Tree valves and Pipe lines. Ring joints Gasket are strictly manufactured as per API-6A and ASME B16.20 specification.

The Octagonal cross section Ring Joint is the development oval cross section and offers a better sealing performance. Only oval cross section gaskets can be used when the flange grooves are with the round bottom. Both Octagonal and oval cross sectioned gaskets can be used when the grooves of the flange are having a flat bottom.

we supplies ring joint gaskets (RTJ Gasket) with the hardness numbers as follows:
