ECONOMICAL  ADVANTAGES  OF PVC PIPES
   
  • Installation  is quite easier, saving in handling and Transportation Costs
     
  • Savings in pumping Costs due to less  Frictional  loss

  • More discharge of Water, Better flow 30 % more flow than GI Pipe

  • Longer life of the Pipe. Low maintenance and replacement costs

  • Reduced installation Cost. Ensure speedy implementation of the scheme

  • Considerably reduced cost due to Saving in Material cost and Installation cost both

  • Uniform flow of Water throughout, no danger of contamination due to incrustations.
