PVC-U Industrial Pipe

PVC-U Industrial Pipe

// Introduction //

PVC-U pipes and fittings for industrial applications are made by polyvinyl chloride (PVC) resins and the additives necessary for the manufacture and performance requirements of GB/T4219-2008 Unplasticized polyvinyl chloride (PVC-U) pipes for industrial applications.

Note:

1. considering safety, min. wall thickness ≥2.0mm.
2. besides other regulations, specifications should meet GB/T 10798.

// Characteristics //

1. Weight light, load and transport portable

PVC-U pipe proportion is only steel pipe and iron pipe 1/5, concrete pipe 1/3. Pipe weight is about the same specification and length ductile iron pipe 1/4, concrete pipe 1/10. Therefore, PVC-U pipe is load and transport portable and can reduce transport cost.1/2-1/3.

2. Resistant acid, no rusty, no corrode treatment.

3. Smaller flowing resistance

PVC-U pipe inside wall is smooth and smaller flowing resistance, manning coefficient is 0.008-0.009, CONVEY water is more than iron pipe 20%, and more than concrete pipe 40%.

4. Service life

Traditional pipe service life is 20-30years. PVC-U pipe service life is at least 50yearsat a set temperature and pressure..

5. installing simple

PVC-U pipe weight light and convenient, has some ductile. For installing ,comparable with other pipes, pipe system is more complex PVC-U pipe virtues is more prominent.

6. Repair easily

PVC-U pipe repairing cost is only ductile pipe or concrete pipe 30%.

// Performance and parameters //

PVC-U Industrial Pipe color

Color is generally gray. It may be agreed upon between the purchaser and the seller.

PVC-U Industrial Pipe Appearance

The internal and external surfaces of the pipe shall be smooth, clean and free from scoring, cavities and other surface detects. The material shall not contain visible impurities. The ends of the pipe shall be cut cleanly and square to the axis of the pipe.

// Application fields //

PVC pipe is a kind of macromolecule polymer, the molecules containing polar radical chlorine, thus chemically extremely stable, and has excellent corrosion resistant. PVC pipe can resist common acid, alkaline, alkaline solution, but will be corrupted by the aromatic, hydrocarbon, ketone, ester and other chemical substances.

Note: when transporting chemical, pipes should perform Corrosion test.
