304SS oval ring joint gasket,
150LB metal o ring,
150LB seal ring gasket
RTJ gaskets are designed to seal by “initial line contact” or wedging action between the mating flange and the gasket. It is essential to choose a softer metal of the gaskets while the flange’s material should be harder to make sure the ring type joints can give a very tight and efficient seal after applying pressure on the sealing interface through bolt force. Usually, the ring gaskets are used in oil, petroleum and chemical process fields. As precision machined, metallic sealing rings, ring joints are suitable for high pressure and high-temperature applications.
• The original ring joint design.
• Used to standard ring joint flat bottom groove flanges.
• Can be used on older round bottom groove flanges.
• Available in ring no. R11 to R105.

API 6A Spec.
Under axial compressive load, ring type joints plastically deform and flow into the irregularities of the flange groove. Since the contact area of the ring type joint is relatively small, a very high compressive load results between the sealing surface of the ring type joint and the flange groove. This surface pressure is further increased especially by the RX and BX RTJ variants. Both variants are able to seal extremely high internal pressures. RTJ gaskets are produced from metal, so they remain in their compressed form, even when the surface pressure is relaxed. The sealing function of the RTJ gasket is reinforced by the axial forces acting on the sealing surfaces.
RTJ gaskets are available as standard in soft metal and in 304, 316 and stainless steels. Versions in other materials on request.
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
- Metal-to-metal contact creates a reliable seal
- Suitable for extreme pressure and temperature requirements
- Certified quality (including surface hardness)

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 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.
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.
