Ring-type joint (RTJ) gaskets are manufactured from metallic materials in compliance with American standard ASME B 16.20 and the API specification. Detailed monitoring of every manufacturing step guarantees that the sealing rings offer the necessary surface hardness. This creates a functional seal without damage to the flanges. This gasket type is used successfully in downstream refinery applications, for example. RTJ gaskets are also commonly used in high-pressure valves and the associated pipe connections and in pressure vessel joints.
Style R ring type joints are manufactured on oval (2962/R) and octagonal profiles (2961/R).
Both styles are interchangeable in the modern flat bottomed groove.
Octagonal profile joints are interchangeable on flat bottomes groove flanges which have a 23 degree angle groove wall
Style R ring type joints are designed to seal pressures up to 6,250 PSI (425 bar) in accordance with ASME B 16.5
ratings and up to 5,000 PSI (340 bar) in accordance with API 6A pressure ratings.
we supplies ring joint gaskets (RTJ Gasket) with the hardness numbers as follows:

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.
Programming interface ring Joint gaskets come in two fundamental sorts, an oval cross segment and an octagonal cross segment. These essential shapes are utilized in pressures up to 10,000 Rubber Seals and Gasket. The measurements are institutionalized and require uniquely notched spines. The octagonal cross segment has a higher fixing proficiency than the oval and would be the favored gasket. Be that as it may, just the oval cross segment can be utilized in the old sort round base notch. The more up to date level base furrow configuration will acknowledge either the oval or the octagonal cross segment. The fixing surfaces on the ring joint sections must be easily completed to 63 smaller scale inches and to be liberated from shocking edges, apparatus or babble marks. They seal by an underlying line contact or an edging activity as the compressive powers are applied.
