  Product characteristics

  (1)Reliable connection:Polyethylene pipeline system is connected by electrothermal fusion,the strength of the joint is higher than the strength of the pipeline body.Polyethylene pipeline is connected with other pipelines by flange,which is convenient and fast.

  (2)Excellent impact resistance at low temperature:polyethylene has very low temperature embrittlement temperature and can be safely used in the temperature range of-60~60 C.In winter construction,because of the good impact resistance of materials,brittle cracks of pipes will not occur.

  (3)Excellent stress cracking resistance:HDPE has low notch sensitivity,high shear strength,excellent scratch resistance and outstanding environmental stress cracking resistance.

  (4)Excellent chemical corrosion resistance:HDPE pipeline can resist the corrosion of various chemical media,and the chemical substances existing in soil will not have any degradation effect on the pipeline.

  (5)Aging resistance and long service life:polyethylene pipes containing 2%~25%uniformly distributed carbon black can be stored outdoors or used for 50 years without being damaged by ultraviolet radiation.

  _Good wear resistance:The wear resistance test of HDPE pipeline and steel pipe shows that the wear resistance of HDPE pipeline is four times that of steel pipe.In the field of slurry transportation,HDPE pipeline has better wear resistance than steel pipe,which means that HDPE pipeline has longer service life and better economy.

  Good flexibility:HDPE pipeline flexibility makes it easy to bend,engineering can change the direction of the pipeline to bypass obstacles,in many cases,pipeline flexibility can reduce the amount of pipe fittings and installation costs.

  _Low flow resistance:HDPE pipeline has smooth inner surface and its Manning coefficient is 0.009.Smooth surface and non-sticking characteristics ensure that HDPE pipeline has higher transport capacity than traditional pipelines,and also reduces pressure loss and water transmission energy consumption of pipelines.

  Convenient handling:HDPE pipes are lighter than concrete pipes,galvanized pipes and steel pipes.It is easy to transport and install,and lower human and equipment requirements mean that the installation cost of the project is greatly reduced.

  _There are many kinds of construction methods:HDPE pipeline has a variety of construction technologies.Besides traditional excavation methods,it can also be constructed by a variety of new trenchless technologies,such as pipe jacking,directional drilling,liner,crack pipe,etc.This is the only choice for some places that are not allowed to excavate,so HDPE pipeline is more widely used.

  Application area

  (1)Urban water supply:HDPE pipeline has comprehensive advantages of safety,sanitation and convenient construction,and has become an ideal pipe material for urban water supply.

  (2)Food and chemical industry:HDPE pipeline has unique chemical corrosion resistance,which can be used for transportation or discharge of various acid-alkali-salt solutions.It has long service life and low installation and maintenance cost.

  (3)Transportation of ore sand and slurry:The wear resistance of HDPE pipeline is four times that of steel pipe.It can be widely used to transport ore sand,fly ash of power plant,slurry of river dredging,etc.

  (4)Replacement of cement pipes,cast iron pipes and steel pipes:For the reconstruction of old cement pipes and cast iron pipes laid in the city,HDPE pipes can be directly inserted into the old pipes without large-scale excavation,which has low cost and short construction time,and is especially suitable for the pipeline transformation in the old urban areas.

  Landscape greening network:Landscape greening requires a large number of water pipelines,HDPE pipelines are low-cost,worthy of vigorous promotion.
