11、ethylene(PEX-AL- PEX) pressure pipe F128290Polyethylene/Aluminium/Polyethylene (PE-AL-PE) composite pressure pipe The Committee decided to use the terminology macro-composite to better describe the pipe structure. The term macro reflects the three separate component layers working together in the pi
12、pe wall as opposed to the more common fibre-reinforced composite pipe structures. The terms normative and informative have been used in this Standard to define the application of the appendix to which they apply. A normative appendix is an integral part of a Standard, whereas an informative appendix
