Energy-saving HDPE Solid Wall Pipe High-speed Extrusion Machine

(1) reliable connection: polyethylene pipe systems are connected by electrothermal fusion, and the strength of the joint is higher than that of the pipe body

(2) good low-temperature impact resistance: the low-temperature embrittlement temperature of polyethylene is very low, and it can be used safely in the temperature range of - 60-60 ℃. During construction in winter, pipe embrittlement will not occur due to the good impact resistance of the material.

(3) good stress cracking resistance: HDPE has low notch sensitivity, high shear strength and excellent scratch resistance, and its environmental stress cracking resistance is also very outstanding.

(4) good chemical corrosion resistance: HDPE pipeline can resist the corrosion of a variety of chemical media, and the chemicals in the soil will not cause any degradation to the pipeline. Polyethylene is an electrical insulator, so it will not rot, rust or electrochemical corrosion; In addition, it does not promote the growth of algae, bacteria or fungi.

(5) aging resistance and long service life: polyethylene pipes containing 2-2.5% uniformly distributed carbon black can be stored outdoors or used for 50 years without being damaged by ultraviolet radiation.

(6) good wear resistance: the comparative test of wear resistance between 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 pipe, HDPE pipe has better wear resistance, which means that HDPE pipe has longer service life and better economy.

(7) good flexibility: the flexibility of HDPE pipeline makes it easy to bend. In engineering, obstacles can be bypassed by changing the pipeline direction. In many cases, the flexibility of pipeline can reduce the consumption of pipe fittings and reduce the installation cost.

(8) small flow resistance: HDPE pipe has smooth inner surface, and its Manning coefficient is 0.009. The smooth performance and non adhesion characteristics ensure that HDPE pipeline has higher transportation capacity than traditional pipes, and also reduce the pressure loss and water transmission energy consumption of the pipeline.

(9) convenient handling: HDPE pipe is lighter than concrete pipe, galvanized pipe and steel pipe. It is easy to handle and install, and lower labor and equipment requirements mean that the installation cost of the project is greatly reduced.

(10) a variety of new construction methods: HDPE pipeline has a variety of construction technologies. In addition to the traditional excavation method, it can also be constructed by a variety of new non excavation technologies, such as pipe jacking, directional drilling, lining, pipe cracking, etc., which is a good choice for some places where excavation is not allowed.
