PVC-U pipes are mainly made of sanitary grade polyvinyl chloride (PVC) resin, with the addition of appropriate stabilizers, lubricants, fillers, color enhancers, etc. They are extruded by plastic extruders and injection molded by injection molding machines. Through cooling, curing, shaping, inspection, packaging and other processes, the production of pipes and fittings is completed.

The seismic performance of PVC-M pipe, a modified product of PVC pipe products, is comparable to PVC-U, with toughness reaching 5-10 times higher than UPVC without significantly reducing long-term strength, and notch impact strength ≥ 30Mpa (20 ℃), which is more than 3 times higher than UPVC. After the toughness is improved, the sensitivity to damage decreases, and the pipe is less likely to be injured or the degree of injury is greatly reduced, which reduces the impact on long-term strength. Therefore, a safety factor of 1.6 can be used for the design. Although the cost per ton of PVC-M is higher than that of UPVC, due to the low insurance factor and thinner wall thickness, the price per meter is not higher than that of UPVC.

Product features:

1. Non toxic and hygienic: No scaling, no growth of algae and other microorganisms during use, and no secondary pollution to water quality.

2. Lightweight: The weight per unit length is only 1/5 of that of cast iron pipes.

3. High strength: The tensile strength at 230 ℃ can reach over 45Mpa.

4. Low resistance: The inner wall of the pipe is smooth, without scaling, and the head loss along the same diameter pipe is more than 30% lower than that of cast iron pipe, which can save a lot of operating power costs.

5. Corrosion resistance: It has good acid resistance, alkali resistance, chemical corrosion resistance, good electrical corrosion resistance, and will not cause pitting corrosion during use.

6. Easy to install: Flexible connection, rubber ring sealing, easy installation, good sealing performance.

7. Long service life: Under normal working conditions, the service life of traditional pipes is 20-30 years, while the service life of PVC-U can reach 50 years.

8. Low cost: The transportation and installation costs are low, the material costs are cheap, and the total project cost is 30% lower than that of cast iron pipes.
