nodweddion pibell bibell hdpe

Mae HDPE yn biblinell dda, nid yn unig y dylai gael economi dda, ond dylai hefyd fod â chyfres o fanteision megis rhyngwyneb sefydlog a dibynadwy, ymwrthedd effaith materol, ymwrthedd crac, ymwrthedd heneiddio, ymwrthedd cyrydiad, ac ati O'i gymharu â phibellau traddodiadol, piblinell HDPE Mae gan y system y gyfres ganlynol o fanteision:

(1) Cysylltiad dibynadwy: Mae'r system bibell polyethylen wedi'i chysylltu gan ymasiad electrothermol, ac mae cryfder y cyd yn uwch na chryfder y corff pibell.

(2) Gwrthiant effaith tymheredd isel da: Mae tymheredd embrittlement tymheredd isel polyethylen yn hynod o isel, a gellir ei ddefnyddio'n ddiogel yn yr ystod tymheredd o -60-60 gradd. Yn ystod y gwaith adeiladu yn y gaeaf, oherwydd ymwrthedd effaith dda y deunydd, ni fydd y bibell yn frau.

(3) Gwrthwynebiad da i gracio straen: Mae gan HDPE sensitifrwydd rhicyn isel, cryfder cneifio uchel a gwrthiant crafu rhagorol, ac mae ei wrthwynebiad i gracio straen amgylcheddol hefyd yn rhagorol iawn.

⑷Good chemical corrosion resistance: HDPE pipes are resistant to corrosion by a variety of chemical media, and chemical substances in the soil will not cause any degradation to the pipes. Polyethylene is an electrical insulator, so it does not rot, rust or electrochemically corrode; it also does not promote algal, bacterial or fungal growth.

⑸Aging resistance, long service life: polyethylene pipes containing 2-2.5 percent evenly distributed carbon black can be stored or used outdoors for 50 years without being damaged by ultraviolet radiation.

⑹ Good wear resistance: The comparison test of wear resistance of HDPE pipe and steel pipe shows that the wear resistance of HDPE pipe is 4 times that of steel pipe. In the field of mud transportation, compared with steel pipes, HDPE pipes have better wear resistance, which means that HDPE pipes have longer service life and better economy.

⑺Good flexibility: The flexibility of HDPE pipes makes it easy to bend, and in engineering, obstacles can be bypassed by changing the direction of the pipes. In many occasions, the flexibility of the pipes can reduce the amount of pipe fittings and installation costs.

⑻ Small water flow resistance: HDPE pipe has a smooth inner surface, and its Manning coefficient is 0.009. The smooth performance and non-adhesive properties ensure that the HDPE pipe has a higher conveying capacity than traditional pipes, and also reduces the pressure loss of the pipeline and the energy consumption of water conveying.

⑼ Easy to handle: HDPE pipes are lighter than concrete pipes, galvanized pipes and steel pipes. They are easy to handle and install, and lower manpower and equipment requirements mean that the installation cost of the project is greatly reduced.

⑽Various new construction methods: HDPE pipes have various construction techniques. In addition to traditional excavation methods, various new trenchless techniques such as pipe jacking, directional drilling, lining, It is a good choice for some places where excavation is not allowed.
