Pipe wrapping inner tape series products are designed for the anti-corrosion of buried and overhead steel pipeline welds and the thermal insulation repair of thermal insulation pipelines. It is composed of radiation cross-linked polyolefin base material and special sealing hot-melt adhesive. The special sealing hot-melt adhesive can form a good bond with the polyolefin base material, the surface of the steel pipe and the solid epoxy coating.
When the pipe wrapping inner tape is heated and installed, while the base material shrinks radially, the inner composite adhesive layer melts and tightly wraps the patch, forming a firm anti-corrosion body together with the base material outside the pipe. Excellent wear resistance, corrosion resistance, impact resistance and good resistance to UV and light aging. Mainly used for elbows, straight pipes, full anti-corrosion, tees, flanges and other parts.
Pipe wrapping inner tape began to be used in the oil and gas industry in the mid-to-late 1990s for the anti-corrosion of welded joints of oil and natural gas steel pipes for long-distance transportation. Anti-corrosion of hot steel pipe joints, anti-corrosion of water pipe joints and other fields. This paragraph from the steel pipe anti-corrosion significance. The corrosion status of oil and gas steel pipes An introduction to the anti-corrosion wrapping tape for oil and gas steel pipes, the requirements for the anti-corrosion wrapping tape for oil and gas steel pipes, and the application prospects of the anti-corrosion wrapping tape in the oil and gas industry. Pipe wrapping is described in five aspects Application of inner tape in steel pipe anticorrosion.
