Nickel 200 Oval Ring Joint Gasket

We are engaged in supplying high quality Ring Joint Gaskets. These are primarily used by the oil, gas, petrochemical and offshore industries; they are also commonly used on valve, pipe work assemblies and with some integrity vessel joints. Ring joint gaskets are specifically designed accurately to form a metal to metal seal with the flanges, primarily used to seal flanged connections subject to high pressures and temperatures. The cross-sections are designed to concentrate the bolt load over a small area to produce a high seating stress; gasket metal should always be softer than the mating flanges. To create a seal, high seating stressed has to be formed. The seal of the RX' and 'BX' gaskets are pressure activated by sealed media, which is mainly responsible for the improved efficiency of the seal as the internal pressure of the system increases.
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 have over 10 years experience in export business. Our products are sold to Southeast Asia, Middle East, Europe and America and well appreciated by our clients.

Oval cross-section Industry Ring Joint Gaskets and Octagonal cross section Ring Joint Gaskets are used in pressures up to 10,000 psi

The hardness of the ring gasket should always be 30% lesser than the hardness of the flanges to prevent flange deformation

Dimensions and Tolerances for Ring Joint Gaskets and Grooves are covered in API 6A and ASME B16.20.

We stock a wide range of sizes and materials ready for immediate shipment from Ring Numbers R11 to R105.

ring joint gasket is machined from solid metal in a variety of shapes according to API 6A & ASME B16.20 standards,it’s designed for high pressure ,high temperature or highly corrosive applications by selecting the most suitable material and shape. It is designed to with stand exceptionally high assembly loads over a small area, thus producing high seating stresses.Ring type Joint Gaskets are designed to seal by "initial line contact" or wedging action between the mating flange and the gasket. By applying pressure on the seal interface through bolt force, the softer metal of the gasket flows into the imperfections of the harder flange material, creating a very tight and efficient seal.

The contact face is in oval shape. It provides a high reliabililty seal. These gaskets are manufactured in accordance to API 6A of ASME B16.20 to suit API613 and ASME/ANSI B16.5 Flanges. Fits the round and flat bottom ring groove flange

As a result of metal to metal sealing media they are made to be free of indentations, tool marks etc and have a surface finish of maximum,

· R, RX – 63 microinches Ra (1.6 micrometer Ra).
