PVC water supply pipe characteristics and material characteristics

July 25, 2021

The PVC water supply pipe is made of hygienic PVC resin as the main raw material, adding a certain amount of stabilizer, lubricant, filler, coloring agent, etc., and is extruded by plastic extruder and injection molding machine, through cooling, solidification, A water supply pipe produced by stereotypes, inspection, packaging, etc.

main feature

1. Light weight, convenient for handling and loading: low density, convenient for handling, loading and unloading and construction.

2. Excellent corrosion resistance: It has excellent acid resistance, alkali resistance and corrosion resistance, and is suitable for the chemical industry.

3. The fluid resistance is small: the inner wall of the pipe is smooth, its roughness coefficient is only 0.009, and the fluid resistance is small, which effectively improves the hydraulic conditions of the pipe network and reduces the operating cost of the system.

4. High mechanical strength: The pipe has good pressure resistance, impact resistance and tensile strength.

5. Simple construction: Pipeline connection construction is quick and easy, and construction engineering costs are low.

6. Low cost: low price, convenient transportation and construction, long service life, so the overall cost is low.

7. Does not affect water quality: It is confirmed by the dissolution test that it does not affect the water quality, and is suitable for large-scale promotion and application.

Material properties

ABS (acrylonitrile-butadiene-styrene copolymer)

ABS is used to transport drinking water, mud and chemicals. The DWV (Drain Waste Exhaust) application is the most commonly used.

Unplasticized polyvinyl chloride (UPVC) and CPVC (post-chlorinated polyvinyl chloride)

UPVC has excellent chemical resistance over the entire operating temperature range and has a wide range of working pressures. Due to the long-term high-strength characteristics, rigidity and cost-effectiveness, UPVC systems account for a considerable proportion of plastic pipe installations.

CPVC is resistant to a variety of acids, bases, salts, paraffins, halogens and alcohols. This is not solvent resistant, aromatic hydrocarbons and certain chlorinated hydrocarbons.

PP (polypropylene)

Polypropylene is suitable for use in food, drinking water and ultra-pure waters, as well as in the pharmaceutical, chemical and other industries.

PE (polyethylene)

Polyethylene has been successfully used for many years for the safe delivery of drinking water and wastewater, hazardous waste, and compressed gases.
