Ring Type Joint-Oval

Ring Type Joint-Oval 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

Product Description

Ring Type Joint-Oval 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. 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 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.

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

We stocks a wide range of sizes and materials ready for immediate shipment from R11 to R105. Stock materials include large variety of metals.
