Advantage
1. Has higher compressive strength and creep resistance.
2. It has a higher rigidity and impact resistance than ordinary pure plastic pipes, similar to the low linear expansion coefficient of steel pipes.
3. Smooth inner wall, no scaling, low water flow friction resistance, high water delivery capacity, and reduced energy consumption.
4. Good corrosion resistance, the inner and outer layers of the pipe are made of plastic, which has the same excellent anti-corrosion performance as plastic pipes.
5. Lightweight, convenient for loading, unloading and transportation.
6. Adopting electric fusion connection, the construction is fast and convenient, and the joint does not leak.
7. Due to the composite structure of steel and plastic materials, it overcomes the phenomenon of rapid stress cracking in plastic pipes.
8. Good wear resistance, with a service life of 50 years under normal use.
Application
1. Municipal engineering: Urban building water supply and drinking water transportation
2. Chemical industry: processes for transporting corrosive liquids in industries such as acid, alkali, salt manufacturing, textile, printing and dyeing, etc
Pipes and discharge pipes:
3. Metallurgical mines: transportation of corrosive media in mines, non-ferrous metal slurry industry, and non-ferrous metal platform refining. 4. Oil and gas fields: long-distance pipeline transportation of oil and water such as petroleum:
5. Agricultural irrigation pipes
