The RTJ standard size gaskets are manufactured in accordance to API-6A and ASME B16.20 specifications. JSY is licensed by the American Petroleum Institute (API).
Products Description
Octagonal Ring Joint Gaskets (Style No: RS2-Ra) and Oval Ring Joint Gaskets(Style No: RS2-Rb)
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 (64 ***). The dimensions are standard- ized and require specially grooved Flanges. The octagonal cross section has a higher sealing efficiency than the oval and would be the preferred gasket. However, only 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 be free of objectionable ridges, tool or chatter marks. RTJ assemblies seal by an initial line contact or an edging action as the compressive forces are applied. The hardness of the ring should always be less than the hardness of the flanges to prevent flange deformation.Dimensions for standard ring joint gaskets and grooves are covered in ASME B16.20 and API 6A, API 17D and ASME B16.5/B16.20.
RX Ring gaskets are similar in shape to the standard octagonal ring joint gasket but their cross section is designed to take
advantage of the contained fluid pressure in effecting a seal. They are made to API 6A and interchangeable with standard octagonal rings for oil field drilling and production applications in API 6B flanges. RX is used at pressures up to 15,000 psi (103 ***).Standard sizes are stocked in low carbon steel, 304 and 316.
The BX ring gasket differs from the standard oval or octagonal shape since it is square in cross section and tapers in each corner. All BX ring type joints incorporate a pressure passage hole to allow for pressure equalization each side of the sealing faces. On assembly, metal to metal cont |
