good water conservancy condition
Due to the smooth surface of the inner wall of HDPE pipe and the roughness coefficient n = 0.009, when calculating the flow rate according to Manning's formula, the flow rate is about 20% higher than that of reinforced concrete pipe under the condition of the same pipe diameter, I .e. when conveying the same flow rate of sewage, HDPE pipe is selected, and the pipe diameter can be reduced by 10% - 20% higher than that of reinforced concrete pipe.
HDPE pipe is a flexible pipe, so its extension performance can be more suitable for construction and foundation settlement under poor foundation conditions, especially in coastal areas, where there is serious uneven settlement of the foundation. This kind of pipe and pipe can be widely used in this geological condition of uneven settlement.
Because the HDPE pipe is made of 100% high density polyethylene in the hot melt state of the whole pipe, its integrity is good, stable chemical properties, high strength, long service life, up to more than 50 years.
Since the raw material of HDPE pipe is composed of polyethylene with high molecular weight, it can effectively resist the corrosion of acid, alkali, salt and other media and the erosion of untreated industrial wastewater and domestic sewage, and its anti-aging performance is better than that of PVC pipe.
As the pipe edge joint adopts the same material joint port electric fusion welding technology, so that the interface is completely integrated, to ensure that the interface will not leak.
HDPE pipe is currently the normal production of pipe diameter range of DN300-DN4200mm, special requirements can be produced to DN7500 pipes and containers, than PVC pipe production of pipe diameter range greatly increased (PVC pipe diameter greatly DN800mm).
Mortar wear has proved that the life of high density polyethylene (HDPE) pipe is more than 4 times that of steel pipe.

Discussion on Application of Electronic Valve in Air-separation Field in PP Pipe Production Plant
2024/06/20
Solenoid valve is widely used in our production. We must have met many problems related to solenoid valve and dealt with many faults in the maintenance of production. We must have accumulated a lot of experience in dealing with the faults of solenoid valve. However, compared with other I & C faults, we deal with the faults of solenoid valve in maintenance. Now we will discuss this problem with you, I hope to learn more experience from everyone and improve together.
