Durable Large Diameter Plastic Coated Steel Pipe

Durable Large Diameter Plastic Coated Steel Pipe

Large diameter plastic coated steel pipe:

Large-caliber plastic-coated steel pipe is an upgraded version of traditional steel-plastic pipe and galvanized pipe with high cost performance. It has the comprehensive characteristics of high strength, high extensibility, good low temperature brittleness, small expansion coefficient of steel pipe, and plastic pipe corrosion resistance, abrasion resistance, and low fluid resistance. It is a new type of water supply and drainage, anti-corrosion green Large-caliber pipes are being used more and more widely in various domestic industries.

At present, the domestic largest diameter polyethylene plastic-coated pipe has exceeded 3200mm, and the specifications above 2200mm are coated with solvent-free epoxy. It is widely used in seawater treatment, quicksand engineering, ocean engineering, chemical sewage disposal and other projects. It has the advantages of high strength, good toughness, anti-aging, corrosion resistance, long service life, and good combination with insulation layer.

Plastic coated steel pipe for gas:

Its production process: After the base pipe is bought back, it must be pickled to remove the rust and oxide layer, phosphating, drying, sandblasting, purification, and then electrostatic spraying to achieve uniform spraying on the inner and outer walls of the metal pipe, and curing at high temperature to The plastic powder is firmly coated on the surface of the steel pipe, and the inspection is carried out according to the standard and an inspection report is provided. Both epoxy and polyethylene have excellent leveling properties, heat resistance and mechanical properties, as well as good outdoor durability, anti-yellowing properties, good storage stability, and excellent overall performance.
