Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces CJ/T 108-1999 "aluminum-plastic composite pressure pipe (lap welding)", compared with CJ/T 108-1999, the main technical changes
as follows.
--- Added a heat-resistant polyethylene (PE-RT) aluminum-plastic composite pressure pipe and related requirements (see 4.2.1 and Chapter 6);
--- Increased nominal diameter of 18mm aluminum-plastic composite pressure pipe and related requirements (see Chapter 6);
--- Gas-plastic composite pressure pipe with the ambient temperature from -20 ℃ ~ 40 ℃ to -20 ℃ ~ 60 ℃ (see 6.1,1999 version
Table 1);
--- Increasing the peel force requirements of the ring, instead of interlayer adhesive strength requirements (see 6.5.1,.1999 version 5.6);
--- Increased diameter test requirements (see 6.5.2);
--- Pipe specifications grouped, modify hydrostatic test conditions (see 6.7,1999 version 5.9);
--- Increased system suitability test requirements (see 6.12).
This standard proposed by the Ministry of Housing and Urban Standard and Design Institute.
This standard by the Ministry of Housing and Urban Water Supply and Drainage Standardization Technical Committee building centralized.
This standard was drafted. Rifeng Enterprise Group Co., Ltd., the national ceramic and plumbing products Quality Supervision and Inspection Center, Zhejiang double Lin
