Notice on the Issuance of the "Design Standard for Forged Steel Socket Weld Pipe Fittings" To meet the needs of large-scale chemical plant construction, make piping engineering construction factory-based and prefabricated, and solve the problem of introducing spare parts for the equipment, the chemical industry departments (bureaus) of all provinces, autonomous regions, and municipalities directly under the central government, and relevant design units, in accordance with the arrangement of the Ministry of Infrastructure Bureau (87) Chemical Foundation No. 073, the Process Piping Design Technology Center of the Ministry of Chemical Industry organized China Saiqiu Chemical Engineering Company to compile the "Design Standard for Forged Steel Socket Weld Pipe Fittings" based on reference to international standards and combined with my country's specific conditions. This design standard has been reviewed by relevant units and is now approved as a ministerial standard with the number HGJ10-88. From the first It will be implemented from May 1, 1988. The publication and distribution of this standard shall be the responsibility of the Chemical Industry Design Standard Publishing Group. Specific interpretation and other work shall be the responsibility of the Process Piping Design Technology Center of the Ministry of Chemical Industry.

1.1 This socket welding pipe fitting is compiled with reference to the American ANSIB16·11-80, MSSSP-83-1976 and Japanese JISB2316-82 standards, and combined with the actual situation in my country. 1.2 The nominal diameter of this pipe fitting is 1
, 1, 11
inch, and the pipe connected to it is an imperial pipe. The socket hole and flow hole diameter of this pipe fitting can be processed according to the metric pipe size and can be used for metric pipes of DN15, 20, 25, 32, 40.
1.3 The pressure grades of this pipe fitting are divided into 3000 and 6000 pound grades, but the union instrument is used for 3000 pound grade. The reference pipe used to calculate its pressure rating is as follows:

Sch160
The nominal thickness of the pipe represented by Sch80, Sch80S, Sch160 is as follows: Nominal pipe diameter

14 The material of this pipe fitting is 20, 16Mn, 15CrMo and 1Cr18Ni9Ti, 1Cr18Ni9Ti, which is only used for 3000 pound grade.
Note: ① The pipes connected to the pipe fittings are not subject to this restriction, and their wall thickness can be thinner or thicker. If the connected pipe is thinner, the pressure rating should be controlled by the strength of the pipe. If the connected pipe is thicker, the pressure rating should be controlled by the strength of the pipe fittings, and the pressure bearing values ​​of Sch80, Sch80S, and Sch160 pipes listed in the table should also be considered. 1
