METALLIC GASKETS FOR PIPE FLANGES<\/strong><\/h4>The Ring Type Joint gasket, or RTJ gasket, was originally developed for the petroleum refining industry. The refining processes produced extremely high pressures with flammable and explosive medias. The oil fields, rigs, and down hole equipment continue to utilize the RTJ gasket due to their high pressure service capability. Being a metal to metal type solid seal, the RTJ is capable of withstanding extremely high pressures in very hot applications.<\/p>
Ring Joint Gaskets are either octagonal or oval made to ASME B 16.20 in various sizes. API Ring Joint Gaskets come in two basic types, an oval cross section and an octagonal cross section. These basic shapes are used in pressures up to 10,000 psi. The dimensions are standardized and require specially grooved flanges. These are identified by numbers R, RX or BX that relate toFlange size, pressure, class, and appropriate standards ASME B 16.20 or API 6A. Ring Joint Gaskets are manufactured in various types. These Ring Joint Gaskets are developed in accordance toAPI6A & ASME B 16.20 specifications. Materials for these gaskets are selected based on suitability for service conditions. It is essential that Ring Joint Gaskets be of a hardness lower than the Flanges.<\/p>
APPLICATION:-<\/strong><\/p>- Ring type joints excel in high-pressure applications such as oil and gas exploration and production.<\/li>
- RTJs are also used on valves and pipework assemblies in refineries and other process industries.<\/li>
- Sub-Sea wellhead & Christmas tree systems<\/li>
- Ring joint gaskets are metallic sealing rings suitable for high pressure and high temperature applications and are fitted in ring groove type flanges.<\/li>
- Refining<\/li>
- Down Hole<\/li>
- Christmas Tree Processes<\/li>
- Subsea<\/li>
- Super-Heated Steam<\/li>
- API 6A<\/li>
- ASME B16.20<\/li>
- ASME B16.5<\/li>
- ANSI, DIN & JIS Flanges<\/li><\/ul>
Available in both oval and octagonal profiles, standard style R ring type joints are manufactured to meet both API 6A and ASME B16.20 sizes and ratings.<\/p>
Also available are Style RX ring type joints which energizes on assembly. This type is designed to fit the same groove as a style R therefore making them interchangeable. For very high pressures, often found in sub-sea wellhead and Christmas tree systems, the style BX is used. Subsea versions of all styles are available with pressure balance holes.<\/p>
We also design and manufacture special RTJ and bespoke solid metal gaskets for topside and subsea blow-out preventers.<\/p>

These basic shapes are used in pressures up to 10,000 psi. The dimensions are standardized and require specially grooved flanges.<\/p> - The octagonal cross section has a higher sealing efficiency than the oval and would be the preferred gasket.<\/li>
The oval cross section can be used in the old type round bottom groove. The newer flat bottom groove design will accept either the oval or the octagonal cross section. The sealing surfaces on the ring joint grooves must be smoothly finished to 63 micro inches and to be free of objectionable ridges, tool or chatter marks. They seal by an initial line contact or a edging action as the compressive forces are applied.<\/div><\/li><\/ul> The hardness of the ring should always be less than the hardness of the flanges to prevent flange deformation. Dimensions for API ring joint gaskets and grooves are covered in ASME B16.20 and API6A.<\/p> Reliable Steel Distributors are Manufacturers of Following types of Gaskets :<\/p> <\/colgroup>flange gasket<\/td> | bx ring gaskets<\/td> | inconel gaskets<\/td> | ring gasket bx<\/td> | ss gaskets<\/td><\/tr> | ring joint type<\/td> | ring type gasket<\/td> | ring gasket types<\/td> | ring joint gaskets<\/td> | lens ring gasket<\/td><\/tr> | rx gasket<\/td> | ring gasket rx<\/td> | rtj flange gasket<\/td> | incoloy gaskets<\/td> | srx gasket<\/td><\/tr> | monel gaskets<\/td> | r gasket<\/td> | ring joint gasket material<\/td> | duplex gaskets<\/td> | oval ring gasket<\/td><\/tr> | rtj gasket<\/td> | metallic gaskets<\/td> | 304 gaskets<\/td> | octagonal ring gasket<\/td> | ring joint gasket manufacturer<\/td><\/tr> | ring type joint gasket<\/td> | ring gasket material<\/td> | hastelloy gaskets<\/td> | 800ht gaskets<\/td> | ring gaskets<\/td><\/tr> | ring gasket supplier<\/td> | rtj ring gaskets<\/td> | ring type joint gaskets<\/td> | ring type joint<\/td> | sbx gasket<\/td><\/tr> | bx gasket<\/td> | seal ring gasket<\/td> | \u00a0ring joint<\/td> | flat ring gasket<\/td> | stainless gaskets<\/td><\/tr> | gasket ring joint<\/td> | 600 gaskets<\/td> | \u00a0ring gasket<\/td> | 800 gaskets<\/td> | api ring gasket<\/td><\/tr> | api ring gaskets<\/td> | bx ring gasket<\/td> | oval gasket<\/td> | octagonal ring joint gasket<\/td> | 316 gaskets<\/td><\/tr> | 800h gaskets<\/td> | nickel gaskets<\/td> | ring joint gasket<\/td> | 316l gaskets<\/td> | b16.20 gaskets<\/td><\/tr> | ring gasket<\/td> | titanium gaskets<\/td> | rtj gaskets<\/td> | oval ring joint gasket<\/td> | ss316 ring gasket<\/td><\/tr> | ring gaskets for flanges<\/td> | 304l gaskets<\/td> | ring joint flange gasket<\/td> | \u00a0<\/td> | \u00a0<\/td><\/tr><\/tbody><\/table><\/article><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t |
