[Product Introduction]

PVC-U drainage pipes are primarily made from hygienic-grade polyvinyl chloride (PVC) resin as the main raw material, with appropriate amounts of stabilizers, lubricants, fillers, colorants, etc. They are formed through extrusion by plastic extruders and injection molding by injection molding machines. The production process includes cooling, curing, shaping, inspection, packaging, and other steps to complete the manufacturing of pipes and fittings. 

[Performance Characteristics]

1. Excellent physical and chemical properties, resistant to chemical corrosion, high impact strength, low fluid resistance, with a 30% increase in flow rate compared to cast iron pipes of the same diameter. They are aging-resistant, have a long service life of no less than 50 years, making them an ideal material for building water supply and drainage.

 2. Lightweight and durable, easy to install, effectively accelerating project progress.

 3. Cost-saving for construction, significantly reducing construction costs compared to cast iron pipes of the same specifications.

[Advantages of Fittings]

 1. Strong corrosion resistance, unaffected by corrosive soil and various drinking water;

 2. Smooth inner walls, with lower frictional resistance than conventional materials;

 3. Pipes and fittings never rust, so internal erosion and shrinkage do not occur;

 4. Building exteriors will never be stained due to pipe rust, ensuring the building's value remains intact;

 5. A wide variety of pipe fittings, complete and suitable for various design and installation requirements;

 6. Easy installation, no need for regular maintenance;

 7. One-fifth the weight of cast iron pipes, easy to transport and handle;

 8. Adhesive bonding is simple, fast, economical, and efficient; 

9. Odorless and non-toxic;

 10. Resistant to a wide range of chemicals, including strong acids and alkalis;

 11. Immune to bacterial attacks;

 12. Termite-resistant and weather-resistant;

 13. Lower cost than conventional materials;

 14. Service life of over 50 years under normal usage conditions.
