Release Time:
2023-03-10
The materials used for pipeline anti-corrosion are directly related to the quality of pipeline anti-corrosion. Therefore, when anti-corrosion is carried out, the raw materials must pass the test. Different anti-corrosion materials require different raw materials. 1. The main raw materials used in 3PE anticorrosion are polyethylene and polypropylene. 2. Epoxy resin anticorrosion mainly uses epoxy resin composite material coating, phenolic epoxy coating and polymer composite material.

1. The main raw materials used in 3PE anticorrosion are polyethylene and polypropylene.
2. Epoxy resin anticorrosion mainly uses epoxy resin composite material coating, phenolic epoxy coating and polymer composite material.
3. Epoxy coal tar pitch anticorrosion mainly uses asphalt anticorrosion paint and polypropylene non-woven fabric.
4. Cement mortar is mainly suitable for cement mortar anticorrosion.
5. Cold wrapping tape refers to the adhesive tape used for anti-corrosion winding. Cold wrapping tape generally includes polyethylene (composite) type anti-corrosion tape, polypropylene reinforced fiber anti-corrosion tape, aluminum foil anti-ultraviolet anti-corrosion tape, polyethylene 660 type (modified) Asphalt) tape, double-sided adhesive anti-corrosion inner tape (this tape is rarely used in China, but it is very practical and widely used abroad, and is generally used for export) and epoxy coal tar anti-corrosion tape. The implementation standards are SY/T 0414-98 and SY/T0447-96.

6. Heat shrinkable tape is generally used for jointing of anti-corrosion steel pipes
It is designed for the anti-corrosion of buried and overhead steel pipe welds and the insulation repair of heat-insulated pipes. It is composed of radiation cross-linked polyolefin substrate and special sealing hot melt adhesive. The special sealing hot melt adhesive can form a good bond with polyolefin substrate, steel pipe surface and solid epoxy coating.
The characteristics of cold-wound tape and 3PE heat-shrinkable tape are: it is suitable for the main anti-corrosion layer pipes of various materials, while other methods are suitable for the main anti-corrosion layer pipes of the same or similar materials.
