ASME B16.20 ring joint gasket Wellhead Casing head oval rtj gasket

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 hardness of the ring should always be lesser than the hardness of the flanges to prevent flange deformation. Dimensions for ring joint gaskets and grooves are covered in ASME B16.20 and API6A.Asian stocks a wide range of sizes and materials ready for immediate shipment from R11 to R105. Stock materials include large variety of materials

Standard Style R Ring Type Joints are manufactured inaccordance with ASME B16.20 or API 6A.Available in both oval and octagonal configurations, both types are interchangeable on the modern octagonal type grooved flanges.
