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 reliability 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 micro inches Ra (1.6 micrometer Ra).

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