SDR11 Large Diameter Plastic Polyethylene Pipe Flexible HDPE Gas Pipe
----------------------------------------
Basic Info.
The gas pipe must withstand a certain pressure, and usually a PE resin with large molecular weight and better mechanical properties, such as HDPE resin, should be used. HDPE resin has low tensile strength, resistance to pressure difference, poor rigidity, poor dimensional stability during molding and difficult connection, and is not suitable as a material for water supply pressure pipes. However, due to its high hygienic index, LDPE, especially LLDPE resin, has become a common material for gas pipes. LDPE and LLDPE resins have low melt viscosity, good fluidity and easy processing, so the selection range of their melt index is also wide, usually MI is between 0.3-3g/10min.

Advantage
1.Aging resistance, long service life: polyethylene pipes containing 2-2.5% evenly distributed carbon black can be stored or used outdoors for 50 years without being damaged by ultraviolet radiation.
2. 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.
3.Good 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.
4. 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.
5. 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.
6.Various 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 better choice for some places where excavation is not allowed, so HDPE pipes are more widely used.
