Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces CJ/T 125-2000 "gas steel frame polyethylene plastic composite pipe" and CJ/T 126-2000 "gas steel
Polyethylene plastic composite pipe fittings. "
This standard is CJ/T 125-2000 "gas steel skeleton polyethylene pipe" and CJ/T 126-2000 "gas steel
Frame polyethylene plastic composite pipe ", the main technical changes compared with CJ/T 125-2000 and CJ/T 126-2000 are as follows.
--- Increased elastic seal (see 4.4);
--- Increased DN600 specifications pipe, and DN600 pipe corresponding to the various parameters (see 6.3.1.1);
--- Increased resistance of fused pipe fittings and resistance measurement requirements (see 6.6,7.9);
--- Increase the resistance of the fused tube when the storage test requirements (see 9.4.2);
--- Increased flange adapter with O-ring specifications (see Appendix A.1);
--- Modify the polyethylene material properties (see 4.1,.2000 version 4.1);
--- Modify the expression of the pipe (see 5.2, 6.3.2, Appendix B,.2000 edition of Appendix B);
--- Modify the sampling plan, using the acceptance quality limit AQL = 2.5 (see 8.3.2);
--- Remove the bending requirements (see the.2000 version of 6.5, 7.5).
This standard proposed by the Ministry of Housing and Urban Standard and Design Institute.
