The aluminum-plastic composite tape should be tightly wound on the steel or equivalent pipe core, the inner diameter of the pipe core should be 100mm+/-2mm, 150mm+/-2mm, 204mm+/-mm, 406mm+/-mm.The tube core length of the slitted aluminum plastic composite tape should be the same as the width of the aluminum plastic composite tape. The tube core protruding from the end face of the composite tape should be less than 1mm. The tube core length of the unslitted aluminum plastic composite tape should exceed the side of the composite tape by 5-10mm.
