This standard replaces GB/T 13402-2010 "large diameter steel pipe flange", compared with GB/T 13402-2010 main technical changes as follows. --- Revised the outer diameter data of steel pipes according to GB/T 28708-2012; --- Increased flange material and corresponding pressure-temperature rating data; --- Revised the temperature of use of some materials; --- Revised the size data of some flanges; ---Flange sealing surface type adds a flat flange; ---Provisioned on the manufacturing methods of various types of flanges; --- specifies the maximum inner diameter of the butt flange; --- Increased the method of determining the pressure-temperature rating; --- Increased pipe gauge number and steel pipe wall thickness; --- Increased the size of the steel pipe flange of the nominal size DN1650~DN3600. This standard uses the redrafting method with reference to ISO 7005-1.2011 "Pipe Flanges Part 1. Steel for Industrial and General Purpose Piping Systems The degree of conformity with ISO 7005-1.2011 is not equivalent. This standard was proposed by the China Machinery Industry Federation. This standard is under the jurisdiction of the National Pipeline Attachment Standardization Technical Committee (SAC/TC237). This standard was drafted.

Steel Flanges for Industrial and General Purpose Piping Systems" Language and definitions, procurement specifications, processes, pressure limits, materials, precautions during use, other precautions, installation instructions, purchaser prescription letters Technical content such as interest rate, compared with ISO 7005-1.1992, ISO 7005-1.2011 no longer specifies detailed technical parameters, but requires size, Materials, temperature ratings, etc. directly refer to the European Committee for Standardization EN1092-1 "Flange and its connecting pipes, valves, pipes Round Flanges for Accessories and Accessories, PN Marking Part 1. Steel Flanges, American Society of Mechanical Engineers Standard ASMEB16.5 Lan and flange fittings (NPS1/2~NPS24) and ASMEB16.47 "large diameter steel pipe flanges (NPS26~NPS60)". The flange size specified in this standard is interchangeable with ASMEB16.47-2017, and the technical requirements are basically the same, with ASMEB16.47- The main differences in.2017 are as follows. --- This standard is written in a different format than ASMEB16.47-2017; ---ASMEB16.47-2017 is made of inch bolts. The bolt holes are in inch sizes. This standard uses metric bolts and bolt holes. Compatible with metric bolts; ---ASMEB16.47-2017 includes flange data with a nominal pressure of Class400. This standard is not included in Class400. Flange data; ---ASMEB16.47-2017 includes flange metric and imperial unit data (including flange size and pressure-temperature amount) Fixed value), this standard does not include imperial unit data; ---ASMEB16.47-2017 does not have an integral flange. This standard adds the type and size of the integral flange; ---ASMEB16.47-2017 The outer diameter of the steel pipe retains one decimal place. The outer diameter of the steel pipe of this standard is based on GB/T 28708-2012 rounded to an integer number; --- This standard specifies the manufacturing methods for various types of flanges; --- Increased the reference quality of the flange; --- Increased the ordering contract data of the flange; --- Increased pipe gauge number and steel pipe wall thickness; ---Flange material adopts relevant material standards in China, and the pressure-temperature rating is modified according to the material properties of China. This standard gives the ASMEB16.47-2017 related flange material and the corresponding pressure-temperature in the form of an appendix. Rated value --- Increased the size of the steel pipe flange of the nominal size DN1650~DN3600. Large diameter steel pipe flange1 ScopeThis standard specifies the type and parameters, type and size, technical requirements, test, inspection and acceptance, and marking of large diameter steel pipe flanges. Marking, delivery requirements. This standard applies to the nominal pressure Class75~Class900, the nominal size DN650~DN1500 (NPS26~NPS60) Diameter steel pipe flange and flange cover.2 Normative referencesThe following documents are indispensable for the application of this document.
