Description
  • The durability - the term of operation of steel underground pipelines makes no more than 25 years whereas the guaranteed term of operation of polyethylene pipelines makes 50 years.
  • Corrosion firmness - physical and chemical properties of polyethylene guarantee excellent tightness and high stability under the influence of the aggressive substances which are in the soil and the transported environment, during all term of operation, besides, for polyethylene pipes special protection is not necessary (cathodic or anode).
  • Does not demand repair - the polyethylene pipeline does not need repairs that reduces costs of operation.
  • Increase in capacity - in polyethylene and polypropylene pipes does not happen "overgrowing" of internal pass of a pipe oxidation products, as in steel. Diameter of polyethylene pipes on the contrary increases over time at the expense of the creep phenomenon, characteristic of polyethylene (for all term of operation this increase makes about 3). The internal surface of a polyethylene pipe becomes softer and smooth, owing to swelling of a boundary layer of polymer and emergence of specific superficial effect of elasticity which improves conditions of a flow of a wall of a pipe and reduces resistance to the movement.
  • The water which froze in a polyethylene pipe will not damage it.
  • Sag of the house to which the pipeline is brought, will cause destruction of a metal pipe while polyethylene is capable to stretch without loss of the qualities to 7 (for this reason in seismologically dangerous regions of Japan application of polyethylene pipes is approved by the law).
  • Polyethylene pipes toxicological and bacteriological are safe
