Plastic Composite Steel Pipes

Plastic-lined composite steel pipes

A plastic-lined composite steel pipe is made by lining the inner wall of a steel pipe with a layer of plastic, such as polyethylene (PE), heat-resistant polyethylene (PE-RT), or cross-linked polyethylene (PE-X), according to the requirements of the conveyed medium. This creates a two-layer composite structure that combines the high strength and pressure resistance of the steel pipe with the anti-aging, anti-scaling, and wear-resistant properties of the plastic pip


Plastic-coated composite steel pipes

A plastic-coated composite steel pipe uses a steel pipe as the base material and a plastic powder (such as epoxy resin or polyethylene) as the coating material. Through processes like spraying, rolling, dipping, or suction, a plastic layer is melt-coated on the inner surface or both the inner and outer surfaces of the steel pipe

MATUMIZI
  • Municipal Engineering: Urban water supply, drinking water delivery, and firefighting water systems .

  • Chemical Industry: Transportation of corrosive liquids and gases .

  • Oil and Gas Fields: Long-distance transportation of oil, water, and gas mixtures .

  • Other Fields: Including mining, power plant water supply, seawater transportation, and agricultural irrigation


FAIDA

1.Excellent Corrosion Resistance: The plastic layer protects the pipe from corrosion by acids, alkalis, salts, and other chemicals, significantly extending its service life, which can reach up to 50 years .

2.High Strength and Pressure Resistance: The steel layer or steel wire mesh skeleton provides high rigidity and pressure resistance, making them suitable for high-pressure applications .


3.Good Flexibility and Impact Resistance: They are less brittle than pure plastic pipes and can withstand some bending and impact, making them suitable for various installation conditions, including areas with uneven terrain .


4.Smooth Inner Wall: The smooth surface reduces fluid friction and prevents scale buildup, which improves transportation efficiency and saves energy .


5.Lightweight and Easy to Install: They are lighter than pure steel pipes, which simplifies transportation and handling. Connection methods like electrofusion make installation quick and reliable .


6.Hygienic and Non-Toxic: The inner plastic layer is non-toxic and does not breed microorganisms, ensuring the quality of the transported fluid, such as drinking water
