Flange rf significato gasket

Although this specification covers some piping components machined from rolled bar and seamless tubular products (see 5.2 it does not cover raw material produced in these product forms. DOI: 10.1520/A0105_A0105M-14 ASTM International is a member of CrossRef. Answer: RF means "Raised Face." SPWD means "Spiral Wound." (Referring to a gasket for RF flanges) RTJ means "Ring Type Joint." RAISED FACE (RF) FLANGE RF flanges seal with a flat gasket, formerly made of asbestos but now made of more environmentally friendly material, designed. What type of gasket do the different flanges require? For engineering details about flange connected pressure joint, using these gaskets, click here RING TYPE JOINT (RTJ) FLANGE RTJ flanges have grooves cut into their faces which accept steel Ring Gaskets. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

ASTM A105 / A105M - 14 Standard Specification for

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Material shall adhere to tensile strength, yield strength, elongation, reduction of area, and hardness requirements. 1.2 Supplementary requirements are provided for use when additional testing or inspection is desired. In this case the already coined gasket will not bear additional load beyond the bolt tension, vibration and movement cannot further crush the gasket and lessen the connecting tension.

Raised Face Flange (RF Ring Type Joint Flange (RTJ)

Materials shall be subjected to heat treatment (annealing, normalizing, tempering, or quenching). Abstract This specification covers standards for forged carbon steel piping components, that is, flanges, fittings, valves, and similar parts, for use in pressure systems at ambient and higher-temperature service conditions. If this Web Site helps you, or persons for whom you have responsibility, please reward WOODCO USA with your business). Combining values from the two systems may result in non-conformance with the standard. B16.5 Dimensional Standards for Steel Pipe Flanges and Flanged Fittings Available from American Society of Mechanical Engineers (ASME ASME International Headquarters, Two Park Ave., New York, NY, me. 1.4 This specification is expressed in both inch-pound units and SI units. Answer: RF means "Raised Face." SPWD means "Spiral Wound." (Referring to a gasket for RF flanges) RTJ means "Ring Type Joint." RAISED FACE (RF) FLANGE RF flanges seal with a flat gasket, formerly made of asbestos but now made of more environmentally friendly material, designed. This feature will hold the gasket concentric with the bolt circle and bore to make precise assembly easier with the gasket centered on the flange sealing surfaces. The values stated in either SI units or inch-pound units are to be regarded separately as standard. For engineering details about flange connected pressure joint, using these gaskets, click here RING TYPE JOINT (RTJ) FLANGE RTJ flanges have grooves cut into their faces which accept steel Ring Gaskets. A696 Specification for Steel Bars, Carbon, Hot-Wrought or Cold-Finished, Special Quality, for Pressure Piping Components. Follow the links at the bottom of the page.

SPIRAL WOUND (SPWD ) GASKET SPWD identifies a flat gasket used between two RF flanges (without ring grooves). ASTM A105 / A105M - 14 Standard Specification for Carbon Steel Forgings for Piping Applications. RTJ flanges seal when tightened bolts compress the gasket between the flanges into the grooves, deforming (or " Coining the gasket to make Intimate Contact inside the grooves, creating a metal to metal seal. Included are flanges, fittings, valves, and similar parts ordered either to dimensions specified by the purchaser or to dimensional standards such as the MSS, ASME, and API specifications referenced in Section 2.
