Rtj flange dimensions

What is the standard size for a flange? What are the dimensions of a reducing flange? Straightness and alignment of the bolt hole. 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.

RTJ flanges dimensions are covered in ASME B16. Pipe Flanges and Flanged Fittings size NPS ½” to 24” for above NPS 26” to , it should be as per ASME B16.

All dimensions are in millimeters. Tolerances: P = average pitch diameter of ring ±0. Variation in height throughout the entire circumference of any given ring shall not exceed 0. C = width of flat on octagonal ring ±0. Dimensions are in inches. Weld Neck Flange Datasheets The weld neck flange , abbreviated as WNF, is a flange type that is usually used with pipes, as opposed to pressure vessels.

The design of the flange allows for a full penetration weld at its base where it connects to the pipe. Note about cookies This site uses cookies to provide you with a better user experience. This raised face does not serve as any part of the sealing means.

Large Diameter Steel Flanges include NPS through NPS 60. Weld neck flange dimensions are covered in ASME B16. For ring joints with lapped flanges in Classes 3and 60 ring and groove number Ris used instead of R31. The strength for internal pressure of Slip On Flange is two-thirds of Weld Neck Flange. SO flange , one inside and one outside of flange.

A space shall be reserved between the end of the pipe and the end of the flange during welding work, to avoid damage the flange face. RTJ Flange , Alloy Carbon Stainless Steel RTJ Flange manufacturers, Alloy Carbon Stainless Steel RTJ Flange exporter, Suppliers. The ring-type joint face (or RTJ) has grooves cut into the face into which the gasket is placed. For ring type flanges, the flanges seal when tightened bolts compress the gasket into the grooves.

This is referred to as “coining” the gasket. RTJ Flanges , Ring Type Joint Flange Ring Type Joint Flange is a method of ensuring leak proof flange connection at high pressures. A metal ring is compressed into a hexagonal groove on the face of the flange to make the seal. Its mechanical characteristics are between the integral flange and the looping flange.

Ring type joint flange pressure rating includes Class 1to Class 50 PN 2. The structure is simple, and the processing is convenient. So slip on flange welding is widely used in various fluid pipelines. Flanges are furnished face drilled and spot faced or back faced.

API flanges are manufactured for high strength operating refinery systems with products such as oil and explosive gases.

For Ring Gasket number and PCD of Ring Groove see below. API 6A flanges are rated for higher pressures. Flange dimensions are determined by the pipe size and the pressure class required for the application.
