An RTJ or as referred to as ring joint type flange is positioned inside of the flanges bolts while surrounding the pipe bore. In a raised face design, the ASME B16.5 RTJ Flange sits on the raised surface. A benefit of RTJ flanges is that they could be installed without completely dissembling the joint, thereby making it a drop-in gasket. However, a Copper Nickel Rtj Reducing Flanges can also be difficult to clamp in position. Most manufacturers note that since the design requires less material, the cutting operations in comparison to most other fittings tend to be lesser.
Get RTJ Flanges, WN, 2" To 24", 150 RF, SCH 40 * SCH 120, Forged, ASTM A105. ASME B16.5 At Best Price.
When specifying a gasket of Class 900 Rtj Flange Dimensions only three measurements are required. Firstly, the ID or inner diameter which corresponds to the pipe bore; secondly, the OD or the outer diameter which is the same as the OD of the raised face; and lastly, gasket thickness. The ASME B16.5 - 1996 standard for Pipe Flanges and Flange Fittings standard envelopes temperature ratings, PN16 Ring Type Joint (Rtj) Flange Pressure Ratinge, materials, tolerances, dimensions, marking, testing, along with several methods of designating openings for these flanges and flanged fittings. The Standard is limited to flanges such as the ANSI B16.5 Ring Type Joint Flanges and flanged fittings produced from cast or forged material. Included in this Standard are requirements and recommendations regarding Stainless Steel RTJ Pipe Flange bolting, flanges gaskets flanges, and flanges joints.
