This standard is combined with B/584-1376 marine flanges and 1/T11689—1985 marine flanges. The flange size of this standard is GB/T2501 and GB/T712501, of which GB/T2501 is equivalent to GB/T2501-20034, and the effective length of the structure is 13mm = 75mm, which meets the needs of ships entering and exiting. According to the flange size of GB/T2501, the standard is expanded, and the nominal diameter of the PNMP is DNN and DNCO is increased to DN17.i, FN200 and DN2:G. From the date of implementation, this standard will replace GB/T5R1S76H/[11689-198S.CBM48-131, CRM5-181CM1SR.CBM-1281.C-11 and is issued by China National Shipbuilding Industry Corporation. This standard is under the jurisdiction of the 1st Institute of China Shipbuilding Industry Corporation. The drafting unit of this standard is Wen Lian Zao Zhao Xin Guang. The main drafters of this standard are Weng Shiyi, Duan Jinquan, Bi Peixian and Liu Yunxiang. 1 Standard of the People's Republic of China Marine cast steel flange stop valves GB/T 584 1999 GB/T E84-1375 CB/T 11689:98 This standard specifies the flange connection of GB/T56S GB/2501 light steel flange valve (called F valve) product specifications, technical requirements, test methods, inspection rules, marking and packaging.
