Ring joint flange

Ring type joint flange face surfaces are an increasingly popular option with regards to flange connections. RTJ Flanges are a good alternative to raised face in certain applications. The flanges seal when the bolts are tightened and the gasket is compressed into the groove making a metal to metal seal. Ring Type Joint Flange is a method of ensuring leak proof flange connection at high pressures.

This jointing method can be employed on Weld Neck, Slip-on and Blind Flange. A RTJ Flange Joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together, usually has a raised face with the groove machined into the face of the flange.

The edge (periphery) of each ring joint flange shall be marked with the letter R and the corresponding ring groove number. NOTES: (1) The height of the raised portion is equal to the depth of the groove dimension, E, but is not subjected to the tolerances for E. Former full-face contour may be used. A ring joint flange features a circular groove to accommodate a ring joint gasket (oval, or rectangular). Raised face height matches depth of groove.

Other flange facings covered by these standards include the large and small tongue-and-groove facings, and the ring joint facing specifically for ring joint type metal gaskets. Dimensions and Tolerances Type R Ring Gaskets ASME B16. What is a flange pipe joint?

From Blasting And Painting, To Shipment And Storage, We’ve Got You Covered. Ring joint flange have grooves cut into their faces which accept steel Ring Gaskets. A metal ring is compressed into a hexagonal groove on the face of the flange to make the seal. RTJ gaskets are generally used for high pressure.

The Ring type joints are manufactured as per ASME B16. They are dimensionally suitable for use with flanges manufactured. As one of the leaders amongst Manufacturers, Stockist, and Exporters of Ring Joint Flange , ASME B16. A flange can also be a plate or ring to form a rim at the end of a pipe when fastened to the pipe (for example, a closet flange ). A blind flange is a plate for covering or closing the end of a pipe.

A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together. Pipe Flanges and Flanged Fittings for size NPS ½” to 24”. We provide ANSI, API, and AWWA pipe flanges in carbon steel, stainless steel, alloys, and chrome steel. RTJ flanges dimensions are covered in ASME B16.

Style BX Ring Joint Gasket. 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 contact of the flange faces is achieved.

RING JOINT GASKETS R, RX, BX.

As the flanges are bolte the softer material of the ring joint gasket is “squeezed” into the flanges grooves (made of a harder material) and seals the connection very tightly. The Lens ring type of flange joint is used to create a seal in high temperature and high pressure piping systems. This joint differs from the standard raised face flange joint (which has a ‘flat’ sealing face), by having a sealing face angled at 20° down towards the centre of the bore. Limited specializes in manufacturing high pressure, large diameter, high yiel and specialty flanges. Ring Joint Gaskets are designed to seal by initial line contact or wedging action between the mating flange and the gasket.

By applying pressure on the seal interface through bolt force, the softer metal of the gasket flows into the micro-fine structure of the harder flange material, creating a very tight and efficient seal. Lap joint flanges resemble, in shape, slip-on flanges except for the radius at the crossing of the flange face and the bore to accommodate the flanged portion of the stub end. A lap joint flange slips over the pipe and seats on the back of the stub end and the two are kept together by the pressure of the bolts.

Kaxite manufactures and supplies a large variety of ring joint gaskets. The RTJ standard size gaskets are manufactured in accordance to API-6A and ASME B16. Technical - showTechnical.
