High density polyethylene is used as raw material for Gaofeng PE pipeline.Polyethylene is a kind of high molecular weight organic synthetic material,which has both good rigidity and good toughness,and has outstanding advantages in use.The product has the advantages of light material,good flexibility,corrosion resistance,simple installation and construction,earthquake resistance,long service life and low comprehensive cost.Gaofeng PE water supply pipes and pipe fittings are widely used in national key water supply projects,urban direct drinking water pipe network projects,rural water improvement projects,etc.because of their superior quality,which won't produce"secondary pollution".One hundred and twenty-three Advantages of peak PE water supply pipe:1.Significant economic benefits:low project cost(including material cost,construction machinery and labor cost),low investment.2.Long term use value:liquefied gas,artificial gas and most chemicals are corroded,no electrochemical corrosion,long service life,little or no maintenance.Under rated temperature and pressure,it can be used for more than 50 years.3.Superior physical properties:beautiful appearance,smooth inner wall,roughness only 1/6 of steel pipe,small fluid wear resistance.Compared with the metal pipe with the same diameter,it improves the medium flow rate,saves labor consumption,has good low temperature resistance,frost resistance,flexibility and wear resistance,which is 4 times of the steel pipe's wear resistance,and has excellent seismic resistance,impact resistance and wear resistance.4.Convenient construction performance:light weight,raw material density below 960kg/m3,only 1/8 of steel and iron pipe,7/10 of PVC,convenient for transportation and installation.The welding process is simple,easy to handle,bendable,coiling,fast in construction and low in labor intensity.5.Reliable connection performance:the joint strength of butt fusion welding and socket electric fusion welding is higher than that of the pipe itself,and the joint will not be disconnected due to movement or load.Flange or steel plastic conversion joint can be used to connect with other pipes.6.Better energy saving and environmental protection performance:the production of plastic pipes saves about 80%energy than the production of metal pipes with the same effect,with superior heat preservation and energy saving effect,high strength and good performance.The waste material is recyclable,with little environmental pollution,no heavy metal additives,no scaling,no bacteria,and good sanitary performance.
