We, Inflow Valve extends a product line that is impeccable and unique with a complete customer satisfaction experience. We are manufacturers, suppliers, and exporters of a range of Ring Type Joint Flanges (RTJ) that are best-in-class. A Ring type joint flange(RTJ) is a machined metallic ring with a deep groove cut into its face. This groove rests a metal ring which gets compressed when the connecting bolts of the flange are tightened. This compression results in a leak-proof, close-fitting seal on the pipe or connection. Stainless Steel Ring type Joint Flanges are classically used in high-pressure and high-temperature services, while Carbon Steel Ring type Joint Flanges are spill-proof.
