This part is Part 1 of GB/T 9124. This section was drafted in accordance with the rules given in GB/T 1.1-2009. This part replaces GB/T 9112-2010 "Types and Parameters of Steel Pipe Flanges", GB/T 9113-2010 "Integral Steel Pipe Flanges", GB/T 9114-2010 "Threaded steel pipe flange with neck", GB/T 9115-2010 "Butt welding steel pipe flange", GB/T 9116-2010 "Flat welded steel pipe flange with neck", GB/T 9117-2010 "Socket welded steel pipe flange with neck", GB/T 9118-2010 "Butt welded ring with neck Loose steel pipe flanges", GB/T 9119-2010 "plate flat welded steel pipe flanges", GB/T 9120-2010 "butt welded ring plate loose steel pipe flanges" Pipe Flange", GB/T 9121-2010 "Flat Welded Ring Plate Loose Steel Pipe Flange", GB/T 9122-2010 "Flanged Ring Plate Loose Steel Pipe Flange" "Flange", GB/T 9123-2010 "Steel pipe flange cover", GB/T 9124-2010 "Steel pipe flange technical conditions" PN series method The content of the Class series flange is included in Part 2 of GB/T 9124.Compared with the GB/T 9112~9124-2010 series of standards, the main The changes are as follows. ---The content of the PN series flange in the.2010 edition of the standard has been supplemented and revised; ---The nominal pressure range of the flange cover is expanded from PN2.5~PN160 to PN2.5~PN400; ---The nominal size range of neck threaded flanges is modified from DN10~DN1000 to DN10~DN150; ---The outer diameter of the steel pipe has been revised, and the flange size has also been revised accordingly; ---Added the pressure-temperature ratings of some flange materials and materials; ---Relevant contents such as technical requirements have been revised and improved; ---The method for determining the pressure-temperature rating has been added. This part uses the redrafting method to refer to ISO 7005-1.2011 "Pipe flanges-Part 1.Industrial and general purpose piping system steel "Flange" is compiled, and the degree of consistency with ISO 7005-1.2011 is non-equivalent. This part was proposed by China Machinery Industry Federation. This part is under the jurisdiction of the National Pipeline Accessories Standardization Technical Committee (SAC/TC237).

The previous releases of the standards replaced by this part are as follows. ---GB/T 9112~9124-1988, GB/T 9112~9124-2000, GB/T 9112~9124-2010.IntroductionGB/T 9112~9124-2010 series standards are mainly divided into 13 standards according to the different types of flanges. After revision, they are based on the nominal pressure of the flange. "Steel Pipe Flanges Part 2.Class Series". ISO 7005-1.2011 "Pipe Flanges Part 1.Steel Flanges for Industrial and General-Purpose Piping Systems" specifies the technology for steel pipe flanges. Terms and definitions, purchase specifications, technology, pressure limits, materials, precautions for use, other precautions, installation guidelines, purchaser’s regulations letter Compared with ISO 7005-1.1992, ISO 7005-1.2011 no longer stipulates detailed technical Materials, temperature ratings, etc. directly quote the European Committee for Standardization Standard EN1092-1 "Flanges and their connecting pipes, valves, pipes, etc. Round flanges for accessories and accessories, PN identification Part 1.Steel flanges, American Society of Mechanical Engineers standard ASMEB16.5 ``pipe method Lanhe flange pipe fittings (NPS1/2~NPS24)" and ASMEB16.47 "large diameter steel pipe flanges (NPS26~NPS60)". The flange dimensions specified in this part are interchangeable with EN1092-1.2018, and the technical requirements are basically the same. The differences are as follows. ---The writing format of this part is different from EN1092-1.2018; ---According to the use requirements of Chinese users, the nominal size range of the flange has been appropriately expanded, for example. the nominal pressure range has been increased The flange sizes of DN20 and DN32 of PN160~PN400; ---According to the requirements of users in our country, the form and size of the ring connecting surface flange have been added to this section; ---Added the type and size of the socket welding flange with neck; ---EN1092-1.2018 has only one series of outer diameters of steel pipes, and there are two series of outer diameters of steel pipes in this section, of which series Ⅰ The outer diameter of DN10~DN2400 steel pipe is basically the same as that of EN1092-1.2018, but there is a difference between DN65 and DN125 Different, the outer diameter of the DN2600~DN4000 steel pipe of series II is the same as that of EN1092-1.2018; ---The flange material is different from EN1092-1.2018.This part adopts the flange material of our country and refers to EN1092-1.2018 Determined the pressure-temperature rating of our materials; ---Added flange order contract data; ---Increase the pipe table number and steel pipe wall thickness; --- Increase the corresponding relationship between this part and EN1092-1 flange type code and sealing surface code.
