PVC-U large diameter upvc plastic solid wall silencer indoor and outdoor sewage discharge sewage rainwater drainage pipe

Product Description

1. Product Overview

PVC-U drainage pipe: PVC-U pipe is made of sanitary grade polyvinyl chloride (PVC) resin as the main raw material, adding an appropriate amount of stabilizer, lubricant, filler, color enhancer, etc., and is extruded by a plastic extruder and injection molded by an injection molding machine. After cooling, solidification, shaping, inspection,

Packaging and other processes are completed to complete the production of pipes and pipe fittings. It has excellent physical and chemical properties, chemical corrosion resistance, high impact strength, low fluid resistance, 30% higher flow rate than cast iron pipes of the same diameter, aging resistance, long service life, and a service life of not less than 50 years. It is an ideal material for building water supply and drainage.

The national standard of "Rigid Polyvinyl Chloride (PVC-U) Pipes for Building Drainage" is now implemented: GB/T5836,1-2006.

2. Product core advantages

1. Excellent physical properties

- High-strength compression resistance: ring stiffness ≥4kN/m² (can be customized to 8kN/m², 12kN/m²), suitable for buried or high-altitude drainage systems, with strong impact resistance and not easy to deform.

- Strong corrosion resistance: resistant to acids, alkalis, salt spray, and chemical solvents, suitable for industrial wastewater and domestic sewage discharge, with a service life of more than 50 years.

2. Smooth drainage & anti-clogging

- Smooth inner wall: low friction coefficient, high drainage efficiency, reducing dirt deposition and reducing the risk of clogging.

- Large flow design: Optimize the pipe diameter structure and increase the drainage speed, suitable for stormwater drainage systems.

3. Lightweight and easy to install

- Light weight (only 1/5 of cast iron pipes), labor-saving transportation and construction, and reduced labor costs.

- Various connection methods: socket adhesive, elastic sealing ring or flange connection can be used for quick installation, good sealing and no leakage.

4. Environmental protection and safety

- Non-toxic and pollution-free: complies with GB/T5836,1-2006 standard and is suitable for domestic drainage systems.

- Flame retardant and fireproof: self-extinguishing when removed from fire, meeting building fire protection requirements.

5. Economical and durable

- Low overall cost: Compared with cast iron pipes and cement pipes, the procurement and maintenance costs are lower and the price/performance ratio is higher.

- Anti-aging: Adding UV stabilizer, it will not become brittle when used outdoors and has stable long-term performance.

3. Application fields

Building drainage: indoor and outdoor drainage systems for residences, office buildings, shopping malls, etc.

Municipal engineering: urban rainwater, sewage pipe network, road drainage

Agricultural irrigation: farmland drainage, greenhouse water delivery

Industrial wastewater discharge: wastewater discharge from chemical plants, electroplating plants, and food plants

Underground pipe gallery: drainage and sewage pipes of comprehensive pipe network

4. Product Comparative Advantages
