Good water conservancy conditions
Due to the smooth surface of the inner wall of the HDPE pipe and the roughness coefficient of the pipe n=0.009, when the flow rate is calculated according to the Manning formula, the flow rate of the reinforced concrete pipe is about 20% under the same pipe diameter condition. HDPE pipe, its pipe diameter can be reduced by 10%-20% compared to the selected reinforced concrete pipe.
HDPE pipe is a flexible pipe, and its extension performance is more suitable for construction and foundation settlement under poor foundation conditions. Especially in coastal areas, the foundation has serious uneven settlement. This kind and pipe materials can be widely used for this purpose. This is a geological condition of uneven settlement.
High strength and long service life
Because HDPE pipe is a pipe made of 100% high-density polyethylene in a hot melt state, it has good integrity, stable chemical properties, high strength, and long service life, which can reach more than 50 years.
Good corrosion resistance and aging resistance.
Since the raw material of HDPE pipe is composed of high molecular weight polyethylene, it can effectively resist the corrosion of acid, alkali, salt and other media and the corrosion of untreated industrial wastewater and domestic sewage. At the same time, its anti-aging performance is also better than that of PVC pipe. Wait for good performance.
Good sealability, 100% without leakage
Because the pipe edge connection adopts the same material socket joint electrofusion welding technology, the joints are completely integrated and ensure that the joints will not leak.
Light weight, easy installation
Reduce labor intensity and shorten construction period
A wide range of pipe diameters are produced
HDPE pipes are currently produced in the normal diameter range of DN300-DN4200mm, and can be produced to DN7500 pipes and containers when required, which is much larger than the pipe diameter range produced by PVC pipes (the diameter of PVC pipes is larger than DN800mm).
The mortar wear facts prove that the life of HDPE pipes is more than 4 times longer than that of steel pipes.

Jiangsu Xinhai, a manufacturer of HDPE pipe, discusses the performance problems in valve application
Manufacturer Jiangsu Xinhai pipe valve manufacturing Co., Ltd Opening and closing force and moment Opening and closing force and opening and closing moment refer to the force or moment that must be applied to open or close the valve. When closing the valve, it is necessary to form a certain sealing specific pressure between the two sealing surfaces of the headstock and the hair seat. At the same time, it is also necessary to overcome the friction between the stem and the packing, between the threads of the stem and the nut, at the end support of the stem and other friction parts. Therefore, a certain closing force and torque must be applied, The required opening and closing force and moment are variable, and the maximum value is at the final instant of closing or the initial instant of opening. When designing and manufacturing valves, the closing force and torque should be reduced. Opening and closing speed The opening and closing speed is expressed by the time required for the valve to complete an opening or closing action. Generally, there is no strict requirement for the opening and closing speed of the valve, but there are special requirements for the opening and closing speed of the rotor pump in some working conditions, such as some requirements for rapid opening or closing to prevent accidents, some need to close slowly to prevent water hammer, which should be considered when selecting the type of valve.
