Plastic Coated Spiral Welded Steel Pipe

Plastic-coated spiral steel pipe is plastic-coated on the basis of spiral steel pipe, which gives it the following performance advantages:

• 1.1

Resist chemical corrosion: The plastic coating layer can effectively isolate the steel pipe from the contact with the external corrosive medium, and has strong resistance to chemical substances such as acid, alkali and salt in the water.

• 1.2

Resistance to microbial corrosion: The surface of the plastic coating layer is smooth, which is not conducive to the attachment and breeding of microorganisms, and can prevent pipeline damage caused by microbial corrosion. It is suitable for water supply and drainage projects with various water quality conditions.

• 2.1

Resistance to particle erosion: When conveying fluids containing solid particles, such as tailings slurry in mines, mud in construction, etc., the plastic coating layer of the plastic-coated spiral steel pipe has high hardness and toughness, which can effectively resist the erosion and wear of particles, reduce the wear degree of the inner wall of the pipeline, and ensure the conveying capacity and service life of the pipeline.

• 2.2

Reduce mechanical wear: During the installation and use of the pipeline, the plastic coating can reduce the friction between the steel pipe and other objects, reduce the possibility of mechanical wear, and protect the surface of the steel pipe from damage even during frequent loading and unloading and handling.

• 3.1

Meet drinking water standards: The plastic coating material of the plastic-coated spiral steel pipe is usually made of food-grade polyethylene or epoxy resin, etc. These materials are non-toxic, odorless, and will not release harmful substances. They meet the national drinking water hygiene standards.

• 3.2

Not easy to breed bacteria: The surface of the plastic coating layer is smooth, not easy to scale, and has good antibacterial properties. It can effectively inhibit the growth and reproduction of bacteria and algae, keep the inside of the pipeline clean and hygienic, and provide a safe transportation environment for drinking water.
