CR/I11618-1939
This This specification is a reorganization and combination of Ti/T11e18.1-11618.-198 copper header 3. The specifications of the joints are based on the industry standard JIS H3491:1067 and the length and size of the alloy joints. The international standard IS02016:9513 is used as the method for assembly dimensions and tests of pipe capillary seals and Australian standard 753688, etc. 1! ! 4 Water supply copper and alloy are not combined, tight membrane system and explosion-proof end market connection * bear two inner diameter deviations. The nominal diameter of this standard is increased by 1125am.15mm.12N200mm on the basis of G3/_1518.1~116%. Its outer diameter is equivalent to the international standard IS0274; 195 The general size of copper pipes is adopted from the date of implementation. At the same time, it is recommended to transfer G/T11618.1:613.8-198s. The attached 4 of this standard is a reminder.
Li standard is issued by China Shipbuilding Industry Corporation. This standard is drafted by China Shipbuilding Industry Corporation 1 Institute, China Shipbuilding Industry Corporation, China Shipbuilding Industry Corporation, and China Shipbuilding Industry Corporation.
