uPVC Plumbing System

  
  Introduction

Galvanized iron pipes are used for distribution of hygienic drinking water for ages but the quality has been deteriorated over the period of time. Environmentalists & public health engineers all over the world were worried because of contamination of water due to accumulation of rust particles heavily in the GI pipes causing corrosion, algate formulation & root penetration & also reduces the flow of water resulting in choked lines.

Zenith UV stabilized UPVC high pressure threaded plumbing pipes for water distribution are made as per ASTM (American Society for Testing & Materials) specification and are well accepted by the users every where.

Applications

1. Water distribution systems.
2. Pipelines for Chemicals, Compressed air and gases in factories.
3. Water distributions in gardens.
4. Water distribution Systems for bathrooms, washing places, kitchens and toilets in residential blocks, offices, commercial complex, factories, laboratories, as well as bus stands, airports, railways, hotels and hospitals.
5. Water connections for buildings.
6. Tube-well connections

Advantages

1. Distribution of clean & hygienic water.
2. Do not get rusty with passage of time & ensures higher and smooth flow.
3. Low maintenance cost
4. Light weight, convenient to handle, store, transport and install
5. No effect of weather & sunlight due to ultra violets stabilizer.
6. No root penetration.
7. Resistant to chemicals & corrosion.
8. Fire resistant because of self extinguishing quality.
9. Leak proof joints.
10. Non-conductor of electricity & low thermal conductivity.
11. Termites, fungus or bacteria does not effect.
12. Seamless & Strong.
