A Ring Type Joint Flange is termed for pipelines flange with Ring Type Joint Facing. Any Standard & Non Standard Flanges can be machined for Ring Type Joint Facing. A Ring Type Joint is basically a Flange Joint connection or more commonly known as a flange facing.

Ring Type Joint Mechanism
Any two flanges are connected via a mating face with a sealing gasket sandwiched between both the flange facing. Ring Type Joint is special designed cavity over the face side to enclose a oval or rectangular shaped ring when the flanges meet, sealing the joint very tightly.

The Fluid Pressure drops gradually over the joint making it nearly impossible for fluid to escape the joint. Ring Type Joint provides superior connection over raised face, flat face & male female joint.

Designing Ring Type Joint
Ring Type Joint connection can be machined into Weld Neck Flange, Slip On Flange, Blind Flange, Threaded / Screwed Flange, Orifice Flange,  Long Weld Neck Flange, Nipo Flange, Reducing Flange, Weldo Flange & Expander Flanges.
