Product Introduction
PVC-U water supply pipe is a mature pipe material with advantages such as acid resistance, alkali resistance, corrosion resistance, pressure resistance, high strength, light weight, low cost, low fluid resistance, no secondary pollution, meeting sanitary requirements, and convenient construction. Our factory's PVC-U环保 water pipe replaces traditional pipes, prevents secondary pollution, and delivers clean, healthy water. It meets various health standards and is a truly healthy, eco-friendly product.
Features
Light weight: Only 1/5 the weight of iron pipes, easy handling and installation, reduces construction cost.
Corrosion resistant: Excellent acid, alkali and chemical resistance, ideal for chemical industry, wastewater, sewers.
Low fluid resistance: Smooth inner wall, roughness coefficient 0.009 – higher flow capacity, no scaling.
High mechanical strength: Withstands internal pressure, external pressure and impact.
Good electrical insulation: Suitable for wire and cable conduits.
No effect on water quality: Passed dissolution tests, best for drinking water systems.
Excellent water tightness: Reliable sealing with socket or TS joints.
Easy installation: Fast and low-cost construction.
Applications
Tap water projects, electrical engineering, construction, sewer systems, wire/cable conduits, drilling, brine engineering, natural gas, chemical plants, paper mills, electroplating, agriculture, mining, aquaculture, highway engineering, golf courses, fishery, brewing, etc.
