PVC-M high impact resistance water supply pipe

Category: Supply Pipe

Description：PVC-M high impact resistance water supply pipes are made from sanitary grade PVC resin, calcium-zinc/rare earth stabilizers, and incorporate elastomers/inorganic rigid particles for enhanced toughness. This type of pipe maintains the high strength of PVC-U while also possessing good toughness and higher pressure resistance. The ductility and resistance to rapid crack growth of the pipes are significantly improved, resulting in a substantial reduction in accidental damage rates during transportation, construction, and use, potentially even down to zero damage.

Description

　　Product Introduction

PVC-M high-impact water supply pipes are made from sanitary-grade PVC resin, calcium-zinc/rare earth stabilizers, and are processed with the addition of elastomers/inorganic rigid particles for enhanced toughness. This type of pipe maintains the high strength of PVC-U while also possessing good toughness and higher pressure resistance. The ductility and resistance to rapid crack growth of the pipes are significantly improved, greatly reducing the accidental damage rate during transportation, construction, and use, potentially even down to zero damage.

Impact-modified PVC-M water supply pipes can be widely used in urban water distribution networks, urban rainwater and sewage drainage networks, industrial production pipelines, industrial wastewater and drainage pipelines, transporting crushed corrosive materials from mines and quarries, as well as irrigation and vegetation watering systems.

　　Product Features

1. Excellent toughness and impact resistance: PVC-M pipes improve flexibility while maintaining the strength of PVC-U pipes. Their toughness is between that of PVC-U and PE, and compared to ordinary PVC-U pipes of the same specification, their impact resistance is significantly enhanced, allowing them to more effectively resist point loads and uneven foundation settlement.

2. Lightweight and easy to handle: For the same specifications, PVC-M pipes are lighter in weight, making them easier to install, transport, and maintain.

3. Strong water delivery capacity: Compared to PVC-U pipes of the same specification, PVC-M pipes have thinner walls and larger inner diameters, resulting in greater flow capacity and significantly reduced operating costs over time.

4. Long service life: According to foreign research data, PVC-M pipes can last far beyond 50 years under normal working conditions within allowable temperature and pressure ranges.

5. Improved water hammer resistance: They can effectively resist water hammer, preventing damage to pipelines during operation.

6. Enhanced resistance to environmental cracking: They can effectively withstand external impacts during installation and transportation, preventing damage caused by scratching effects and rapid crack growth.

7. Strong chemical corrosion resistance: The PVC-M series pipes have strong chemical corrosion resistance and can be used in any application suitable for ordinary PVC-U pipelines.

　　Application Fields

They can be widely used in urban water distribution networks, urban rainwater and sewage drainage networks, industrial production pipelines, industrial wastewater and drainage pipelines, transporting crushed corrosive materials from mines and quarries, as well as irrigation and vegetation watering systems.
