SN8 high ring stiffness corrugated pipe, Hubei drainage pipe network laying

SN8 high ring stiffness corrugated pipe is a corrugated structure drainage pipe made of high-density polyethylene as the core raw material through a special extrusion molding process. Among them, "SN8" is the pipe ring stiffness grade label, which means that the pipe can withstand an external load of not less than 8 kN per square meter under standard test conditions, and belongs to the category of underground drainage pipes with medium and high load grades. In view of the characteristics of the subtropical monsoon climate in Hubei, with abundant annual rainfall, high peak drainage in the rainy season, and soft geology and high groundwater level in some areas, this pipe is suitable for the laying needs of the local drainage pipe network at the design stage, and can meet the long-term use requirements of most underground drainage scenarios.

core selling point

First, the ring stiffness is up to standard, and the anti-settlement and anti-deformation performance is stable. The ring stiffness index of this pipe fully meets the requirements of the relevant national drainage pipe standards. When it is laid in some geological soft plains and hilly areas in Hubei, it can effectively resist the impact of soil lateral pressure, road traffic load above and groundwater level fluctuations. Under normal operating conditions, there will be no problems such as pipe body collapse and deformation, reducing the probability of structural failure in the later stage of the pipe network.

The second is high flow efficiency and low operation and maintenance cost. The inner wall of the pipe is treated with a smoothing process, and the roughness coefficient is stable at about 0.009. Under the conditions of the same pipe diameter and the same slope, the flow capacity is increased by more than 30% compared with traditional concrete drainage pipes, which can meet the needs of short-term large-flow drainage in Hubei rainy season. At the same time, the inner wall is not easy to adhere to sediment, oil and other sundries, and the probability of sedimentation and blockage is low, which can reduce the manpower and capital investment for later cleaning and maintenance of the pipe network.

The third is excellent corrosion resistance and long service life. The pipe itself has good acid and alkali corrosion resistance, and can be adapted to some partial acid and alkali soil conditions in Hubei without additional anti-corrosion treatment. It can also withstand the long-term initialization of conventional domestic sewage and standard industrial wastewater. Under the premise of compliance laying and normal use, the designed service life is not less than 50 years, which is much higher than the service life of traditional cement pipes, which can reduce the replacement cost of the whole life cycle of the pipe network.

Fourth, it is easy to install and suitable for short-term construction needs. The weight of this pipe is only about 1/8 of that of the same diameter concrete pipe. It does not require large and heavy equipment for transportation and handling. It adopts socket-type elastic sealing connection or hot melt connection process, and the interface sealing performance is good, which can effectively avoid drainage leakage problems. In view of the short construction window in Hubei's rainy season, the installation efficiency of this pipe is increased by more than 40% compared with traditional pipes, which can greatly shorten the construction period and reduce the impact of weather factors on the progress of the project.

Applicable scenarios and suitable populations

In terms of application scenarios, this pipe can be widely adapted to various types of drainage pipe network laying projects in Hubei, including: municipal main and secondary road construction, reconstruction and expansion of drainage pipe network projects, urban old residential rain and sewage diversion renovation projects, industrial park production wastewater discharge pipe network construction projects, farmland water conservancy drainage, irrigation and water transmission channel laying projects, and rainwater collection and transportation pipe network projects in sponge city construction.

In terms of population adaptation, it covers all kinds of subjects involved in drainage projects in Hubei, including municipal engineering construction management units, water supply and drainage project design institutions, engineering construction general contractors, urban pipe network operation and maintenance management departments, industrial park infrastructure management leaders, township water conservancy project builders, etc., which can be selected and used according to the actual load and overcurrent requirements of the project.

The production and testing process of this pipe strictly follows the requirements of relevant national product standards. Each batch of products has undergone a complete performance test before leaving the factory. After the indicators meet the standards, it can be delivered for use. The purchaser can obtain formal product qualification certificates, batch test reports and other documents with the goods. It fully meets the compliance and acceptance requirements of various municipal and civil drainage projects in Hubei, and can provide reliable product support for the long-term stable operation of the drainage pipe network.
