Hierarchical structure of polyethylene adhesive tape
The grade structure and construction method of polyethylene adhesive tape. Polyethylene adhesive tape grade total thickness (mm) Anti-corrosion layer structure:
Ordinary grade ≥0.70 one layer of primer + one layer of inner tape + one layer of outer tape
Reinforced grade ≥1.40, one layer of primer + one layer of inner tape (lap is 50~55% of tape width)
+One layer of outer tape (lap is 50~55% of tape width). In fact, polyethylene anticorrosive tape is mainly used for oil and natural gas transmission; the outer surface of buried steel pipelines such as water supply and drainage and gas transportation in chemical industry and urban construction are anticorrosive, which is convenient for construction.
