Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 12465-2007 "Pipeline compensation joint". Compared with GB/T 12465-2007, the main technical changes
as follows.
--- increase the specifications of some products (see 4.2);
- increased the type of double ball compensating joint (see 4.3.12);
--- increase the material of the product part (see 5.1);
--- Increased burst pressure requirements (see 5.6).
This standard is proposed by China Shipbuilding Industry Corporation.
This standard is under the jurisdiction of the Technical Committee of the National Marine Machinery Standardization Technical Committee (SAC/TC137/SC3).
The drafting unit. Wuxi Jinyang Pipeline Accessories Co., Ltd., China Shipbuilding Industry Comprehensive Technology and Economy Research Institute.
