What are the key features and benefits of PVC pipes in terms of surface variety, electrical insulation, fire resistance, and weather resistance?

Features and General Benefits

  • Internal Surface Variety: The variety of internal surfaces in PVC pipes provides ease of leakage prevention, as it prevents leaks on the inner walls of the pipes, thus reducing losses due to friction.

  • Electrical Insulation Properties: These pipes are electrically insulating and do not allow the passage of electricity or electromagnetic radiation generated by electrical devices or the electrical wiring that may be present.

  • Fire Resistance: PVC pipes are manufactured to be fire-resistant and do not allow flames to spread.

  • Weather Resistance: PVC pipes are specially made to withstand all weather conditions. They are lightweight yet very strong against sunlight and are unaffected by wind or other environmental factors.
