This standard is developed in accordance with the rules given in GB/T 1.1-2009.
This standard replaces HG/T 2130-2014 Glass lined pipes. In addition to editorial changes, the following main technical changes have been made with respect to HG/T 2130-2014:
——The applicable design pressure in Clause 1 "Scope" is revised from "not greater than 1.0MPa" to "not greater than 1.6MPa" (see Clause 1 hereof, and Clause 1 of 2014 edition);
——The schematic diagram of loose flange and the radius dimension r of the outer arc of nozzle are added in Figure 1 (see Figure 1);
—— The technical contents of loose flange are added in Table 1 (see Table 1);
——The dimensions of the outer arc r of nozzle are added in Table 2 (see Table 2);
——The dimensions and reference mass of the nozzle with design pressure of 1.6MPa are added in Tables 2 and 3 (see Tables 2 and 3);
—— "The materials, design, manufacture, inspection and acceptance of glass lined pressure pipes shall also meet the requirements of TSG D0001 and GB/T 20801.5” is added in 4.1 (see 4.1);
——Technical requirements for non-destructive testing of non-pressure pipelines are added in 4.4, i.e. “For non-pressure pipes, non-destructive testing shall be conducted according to NB/T 47003.1.” [See 4.4b)];
——Technical requirements for hydraulic test of non-pressure pipelines are added in 4.5, i.e. “For non-pressure pipes, leakage test shall be conducted according to NB/T 47003.1.” [See 4.5b)];
—— “Value r of glass lined pipe flange should be less than that specified in HG/T 2143.” is added in 4.6 (see 4.6).
——”the ex-factory data of glass lined pressure pipes shall also meet the requirements of TSG D0001” is added in 5.1 (see 5.1).
This standard was proposed by China Petroleum and Chemical Industry Association.
This standard is under the jurisdiction of the National Technical Committee 72 on Glass Lined Equipment of Standardization Administration of China (SAC/TC 72).
The previous editions of this standard are as follows:
This standard specified the type, basic parameters, main dimensions, requirements, ex-factory documents, packaging, transportation and storage of glass lined pipes.
This standard is applicable to glass lined pipes with design pressure not greater than 1.6MPa and design temperature of -20℃ - 200℃.
