What are the materials for corrosion-resistant pipes and what are their uses?
The materials used for pipeline corrosion protection are directly related to the quality of the corrosion protection. Therefore, when carrying out corrosion protection, the raw materials must be up to standard, and different types of corrosion protection require different raw materials.

The materials used for pipeline anti-corrosion are directly related to the quality of the anti-corrosion. Therefore, when performing anti-corrosion, the raw materials must be qualified, and different anti-corrosion methods require different raw materials.
1. The main raw materials used for 3PE anti-corrosion are polyethylene and polypropylene.
2. Epoxy resin anti-corrosion mainly applies epoxy resin composite material coatings, phenolic epoxy coatings, and polymer composite materials.
3. Epoxy coal tar anti-corrosion mainly applies coal tar anti-corrosion paint and polypropylene non-woven fabric.
4. Cement mortar is mainly suitable for cement mortar anti-corrosion.
5. Cold wrap tape refers to adhesive tape used for anti-corrosion wrapping. Cold wrap tape generally includes polyethylene (composite) anti-corrosion tape, polypropylene reinforced fiber anti-corrosion tape, aluminum foil UV-resistant anti-corrosion tape, polyethylene 660 type (modified asphalt) tape, double-sided anti-corrosion inner tape (this tape is rarely used domestically but is very practical and widely used abroad, generally for export), and epoxy coal tar anti-corrosion tape. The execution standards are SY/T 0414-98 and SY/T 0447-96.
6. Anti-corrosion steel pipe joints are generally made with heat shrinkable tape.
It is designed for the anti-corrosion of welded joints of buried and overhead steel pipelines and the thermal insulation of pipelines. It is made of radiation cross-linked polyolefin substrate and special sealing hot melt adhesive, which can form good adhesion with the polyolefin substrate, steel pipe surface, and solid epoxy coating.
The characteristics of cold wrap tape and 3PE heat shrinkable tape are: suitable for anti-corrosion layers of pipelines made of various materials, while other methods are suitable for anti-corrosion layers of pipelines made of the same or similar materials.
