Double-wall corrugated pipe | Double-wall corrugated pipe | Double-wall corrugated pipe price Double-wall corrugated pipe performance and characteristics: Large-diameter double-wall corrugated pipe pipe is a new type of lightweight pipe made of high-density polyethylene as raw material, with light weight , high pressure resistance, good toughness, fast construction, long life and other characteristics. Its excellent pipe wall structure design greatly reduces the cost compared with other structural pipes. And because of its convenient and reliable connection, it is widely used at home and abroad. The Ministry of Construction stipulates that the use of buried pipes is limited to concrete pipes. It is recommended to use large-diameter double-wall corrugated pipes. The prospects are optimistic and it is an updated product for concrete pipes and cast iron pipes.
The main purpose of double-wall corrugated pipes is as buried pipes. Underground drainage pipes transport non-potable water, sewage, rainwater or other gases and liquids to users, sewage treatment plants, and rivers under the action of gravity. Generally, it is transported under biogenic gravity. There is no pressure in the pipe and it only bears the load imposed by the soil. Therefore, the performance requirements for buried pipelines are:. Strength and rigidity (ability to withstand loads in geographical environments). Hydraulic properties (ability to transport liquid). Sealing (no leakage, prevent environmental pollution). Service life (corrosion resistance, wear resistance). Easy to lay and install. Comprehensive economic performance.
First of all: in terms of strength and stiffness. Because plastic buried drainage pipes are flexible pipes, with correct design and construction, plastic buried drainage pipes bear the load together with the surrounding soil, so plastic buried drainage pipes do not need the same stiffness and strength as rigid concrete drainage pipes. . Secondly: In terms of hydraulic properties, plastic pipes have a smooth inner wall and have significantly less resistance to liquid flow than concrete pipes. Practice has proven that at the same slope, plastic underground drainage pipes with smaller diameters can achieve the required flow rate at the same slope. diameter, the use of plastic buried drainage pipes can reduce the slope (reduce the amount of laying work).
Further: Plastic pipes have the most outstanding advantages in terms of service life and corrosion resistance. Domestic sewage and rainwater transported by buried drainage pipes are often corrosive, either acidic or alkaline. Domestic sewage such as industrial drainage is highly corrosive. The corrosion resistance of plastic underground drainage pipes is much better than that of metal pipes, and also significantly better than that of concrete pipes. Plastic pipes are also very resistant to wear and tear.
In addition: in terms of ease of laying and installation, the advantages are also very prominent: light weight, long length (fewer joints), low requirements for pipe trenches and foundations, convenient connection, and fast construction. The advantages of plastic buried drainage pipes are more obvious in crowded urban areas and areas with poor geology (such as high groundwater levels and soft foundations). Finally: In terms of comprehensive economics, the advantages of plastic buried drainage pipes are gradually being recognized. The price of plastic buried drainage pipes is higher than that of concrete pipes. However, domestic and foreign laying experience proves that with correct design and construction, the use of plastic The total project cost of buried drain pipes can often be lower than that of traditional concrete drain pipes. The engineering cost of double-wall corrugated pipes can be close to the cost of concrete flat pipes. The cost is 3-% lower than that of socket concrete pipes, the construction period will be greatly shortened, and the economic benefits are obvious. Production equipment: Adopt CNC technology, the production line is fully automatic, the labor intensity is low, the extruder temperature control accuracy is high, the molding machine can be replaced when the temperature reaches ℃, it can produce a very wide range of pipe specifications, and the mold replacement is convenient for cooling, heating, and the lubrication system is fully automated The module rotation force is small, and there will be no boring phenomenon. It is shaped by vacuum molding. The inner and outer diameters are stable. The wall thickness of the product can be adjusted within a certain range according to user needs.

Short, especially suitable for pipeline renovation in old cities. Five: Urban water supply pipelines have comprehensive advantages such as safety, sanitation, and convenient construction, and have become ideal pipes for urban water supply. 6: Municipal projects Nowadays, pipe seats are the first choice in many municipal sewage discharges, especially in some trenchless projects. The pipe has good toughness and ring stiffness, so it is the best choice to use it as a pipe jack.
