Crat tube instant hot winding forming high-density polymer ethylene (hdpe) wound structural wall pipe. The wall tube is made of high density polymer Vinyl resin As the main raw material, the hot winding poplar process is adopted to ( pp ）Single wall corrugated pipe Special structural walls with high resistance to external pressure are made for the support structure Pipe 。 Clad tube products can be divided into pr, op, sq and vw series.
The performance characteristics of hdpe winding structure wall tube produced by the manufacturer of karat tube and winding structure b-tube in Beixiong County are as follows
1. The hot winding molding fusion seam is of high quality. The flat strip and U-shaped strip extruded from the extruder die in the melting state are evenly wound on the heated drum mold according to the predetermined position, The quality of welded joint of structural wall pipe is improved. The fusion joint of the flat tape in the structural design is covered by the polyethylene coated support pipe, which improves the overall external pressure resistance of the product

2. Installation performance The pipe connection adopts the socket and plug electrofusion connection technology with the same material embedded in the socket, and the connection quality is high. Can be high, The life of the pipeline system is the same and the operation is safe. At the same time, because this product is lighter than other pipes under the same application conditions, it is convenient for transportation, construction is convenient and fast, and construction costs can be reduced. In the scope of application, pipes can be directly laid without the concrete cushion and concrete pipe foundation trench being qualified, basically doing excavation, pipe laying and backfilling at the same time, simplifying the construction process and shortening the construction period. Closed air inspection shall be adopted during project acceptance
3. Good flexibility HDPE winding structure wall pipe has And local pipe sections have strong rigidity and overall external pressure resistance, which can Traffic safety. Due to the flexibility of pipes, the damage loss of pipes can also be reduced to a minimum in case of earthquake, uneven settlement on the surface and other geological activities, thus improving the ability of public facilities to resist earthquakes and reduce disasters
4. hdpe can be recycled, belonging to High density of main raw materials for winding structure wall tubes In the production process, there is no pollution, and the waste pipeline can be recycled to a high standard. Product
5. Corrosion resistance, aging resistance and service life High density polyethylene has strong resistance Ability to corrode and erode. Therefore, the wall pipe of winding structure does not need anti-corrosion treatment when conveying corrosive fluid or laying in corrosive soil, Other pipes. In the design process of the product, select a reasonable product structure, The service life of plastic pipe is more than 50 years and maintenance free within the service life
6. The roughness of the inner wall of the pipe is low, and the roughness of the inner wall of the pipe product around the structural wall with large water delivery volume is about 0.010. Therefore, the specific friction resistance is small when conveying fluid, and the water delivery volume can be greatly increased compared with the cement pipe under the same use conditions, compared with other tickets with the same inner diameter. Therefore, the winding structure wall pipe with smaller inner diameter can be used to replace the cement pipe with larger inner diameter in the application. Under the same conditions, the engineering and Compared with traditional pipes, its properties will be improved and its comprehensive benefits will be obvious, When the construction site is narrow, the buildings are dense, the underground pipelines are complex, the traffic is heavy, and the acid alkali soil is laid,
