How to use polyethylene adhesive tape

Release date:2019-08-23 Author: Click:

Anticorrosive tape is mainly used in oil and natural gas transmission; the outer surface of buried steel pipelines in chemical engineering, urban water supply and drainage, and gas transportation is anticorrosive. It has the characteristics of convenient construction and no pollution. Polyethylene adhesive tape is a tape-shaped anti-corrosion material co-extruded with a polyethylene-based film and thermally laminated with an adhesive layer mainly composed of butyl rubber. Today's polyethylene anti-corrosion tape manufacturers will explain in detail for everyone. How to use it:

1. The temperature when unwinding the tape needs to be above 5 ℃, and the construction of the anticorrosive layer should be performed above -5 ℃. (Experience proves that the tape can be applied at a lower temperature of -30 ° C, but the unwinding temperature must be guaranteed.) When the ambient temperature is lower than 10 ° C, in order to ensure that the tape has good adhesive strength immediately, it should be used. The torch heats the adhesive layer of the steel pipe and baking tape.

2. For the weld, if necessary, it should be reinforced with a narrow strip of tape with a width of 30-50 mm. Cover the weld first and compact it with a hand or a wooden smooth tool.

一分彩3. Use appropriate mechanical or manual tools to spirally wrap the tape on the primed pipe according to the overlap requirements. The tape should maintain a certain tension to make the tape layers tightly connected. When winding the tape, the seam of the tape should be parallel, and the wrinkles must not be twisted. There should be more than 100 millimeters of overlap between the two ends of the tape. If necessary, apply primer or fully bake the end base film of the previous section of tape. After the surface is dry, overlap the beginning of the other section of tape. The beginning and end should be pressed tightly with a wooden smooth tool to prevent it from tilting.

一分彩4. The use of machinery is a powerful measure to ensure the quality of tape winding. It is difficult to achieve uniform surface quality and consistent tension with hand-wound tape. Manual winding can be used only in special circumstances when mechanical construction cannot be performed. However, use narrower tape.

5. When the factory prefabricated tape is wrapped, it can be cold-wrapped or hot-wrapped. It can be pipe rotation (manual rotation or electric rotation), or winding equipment. .

一分彩6. Prefabricated anti-corrosion pipes shall be subject to quality inspection in accordance with the requirements of this standard. After passing the inspection, the factory shall be provided with a certificate of delivery.

一分彩7. When using aluminum foil tape for anti-corrosion of overhead spanning pipes or household risers, they shall meet the relevant construction requirements in this code, but no EDM testing is required.

一分彩8. The anti-corrosion tapes used for mending, elbows and through walls should be as narrow as possible, and construction and testing shall be performed in accordance with the relevant provisions in this code.

一分彩9. For the overhaul of the anticorrosive layer, the rotatable winding equipment should be used for construction at the construction site, and the construction and inspection should be carried out in accordance with the relevant provisions in this code.

The above is the explanation of the use method of polyethylene adhesive tape. It is suitable for anticorrosion and repair of oil, natural gas, chemical, water supply and drainage pipes, straight pipes, elbows, storage tanks, guides and other parts. Welcome to request Customers come to cooperate.
