Polyethylene Winding Structural Wall Tube

Polyethylene Winding Structural Wall Tube

The kra pipe can be divided into PR, OP, SQ, and VW series, among which: PR and OP are mainly used as buried drainage pipes. SQ is mainly used to make containers or inspection wells. VW is mainly used for pipe fittings formed by tee, elbow, and secondary processing. PR series is the most widely used in the products, which has a smooth inner surface and abnormal external reinforced structure. The standard length of the pipe is 6 meters. The inner diameter range of the pipe is DN300-DN4000, and the product indicators all meet the requirements of GB/T 19472.2-2017 type B structure wall pipe standard and EN-13476 European standard. 

The application of HDPE kra pipe 
1. Municipal water supply and drainage: The internal pressure of high-density polyethylene (HDPE) winding reinforced pipe can reach 12kg/cm2, which is the ideal pipe to replace the original drainage cast iron pipe and cement pipe in the city. The pipe can be used for municipal underground drainage, sewage, rainwater collection, water transmission, ventilation, etc to discharge liquid and gaseous substances into rivers or the sea. Thermal structure wall winding pipe has the advantages of lightweight, safe, reliable connection,corrosion resistance, and high ring stiffness, therefore the use of thermal structure winding pipe has great advantages. 
2. Large-scale water conservancy projects: long-distance water transmission, farmland irrigation, reservoir drainage, water source pipe, irrigation pipe and hydropower station water transmission, drainage use; 
3. Environmental protection engineering: deep sea sewage, sewage treatment, waste 
dump sewage, detoxification pipeline. Due to the thermal structure wall winding pipe of various pipe wall structures and pipe, inspection well, pipe fitting, and its reliable connection performance, the pipe can be used for advanced shallow drainage systems. 
4. Petroleum industry: oil, gas pipeline. 
5. Coal industry: coal transport, ventilation systems. 
6. Chemical engineering: chemical containers, especially corrosive fluid delivery 
pipelines. 
7. Electric power engineering: circulating water pipeline. 
8. Road engineering: crossing roads and railways have a large traffic load of water 
culverts and crosswalks; Used as railway and highway road seepage, drainage pipe; The method of "liner in pipe" is becoming more and more important for repairing damaged pipes. 
9. The laying of pipes in a corrosive environment. 
10. Agricultural engineering: farmland, orchard, tea garden and forest belt irrigation, and so on; 
11. Large airport port, wharf engineering: large airport port, wharf engineering drainage, sewage pipe, etc. 
12. Construction engineering: building stormwater pipes, underground drainage pipes, sewage pipes, ventilation pipes, etc. 
Communication tube: railway, highway communications, communication cables, optical cable protection pipe. 
14. Water storage system: used to intercept the slow water storage system. 
15. Special application: thermal winding wall winding pipe can also be used for special 
purposes such as ventilation, passage, desert, swamp, lake area with fluid transport, etc.
