Hollow wall winding pipe has the following characteristics: 1. solve the flat wall pipes resilient sealing strip positioned difficult problems, but also to prevent the installation of the sealing strip seal failure caused a shift fundamentally, greatly improving the quality of .2 special installation. elastic sealing expansion strips solve spiral pipe outer wall infiltration problem, a single point of sealing, the safety factor greatly increased .3 plastic composite material, the inner steel strong structural stiffness, increase the pipe stiffness of joints in by outside When the load and differential settlement, synchronous connections and pipe deformation, so that the pipe to differential settlement and heavy load greatly increased resilience to shocks outer storey density polyethylene material, corrosion resistance, improve service life .4 pipe connection piping system unit length of the bond itself provides a very valuable pipeline system stretching space, is to play a role in expansion joints, so as to solve the thermal expansion and contraction, heavy duty shocks, differential settlement and the reasons for the formation of an axial change longitudinal stress problems excellent installation performance, connectivity simple, rational form joint seal, safe and reliable: pipeline using electrical tape or heat shrink with hot melt connection technology, construction speed, high quality of the connection, the joint strength steel hollow wall winding, ensure that the interface material structure and management body's own unity, and rubber ring type joints or other mechanical joints, is not dangerous because of the presence of the joint and cause leakage. Also, since the product under the same application conditions is lighter than other pipes weight, easy to transport convenient construction speed, can reduce construction costs. In the application, without concrete pads and concrete pipe trench base after passing the tube can be directly deposited, the excavation can be done side, while the down tube, while backfilling, simplifying the construction procedures and shorten the duration. HDPE is a polymer hollow wall winding pipe, hollow wall winding pipe has good flexibility and overall resistance to external pressure hollow wall winding pipe drainage capacity, there is overweight when under load road use, ensure safe passage. Due to the flexibility of the pipe, earthquake, uneven ground subsidence and other geological activity, loss of pipeline damage can be reduced to a minimum, improve the ability of utilities earthquake relief, with good flexibility, seismic performance: 5. Green : Two flat wall use in the manufacture of plastic composite drains and recycling process can do green, the first in its manufacturing process produces no waste gas and waste, environmental pollution; and the manufacture of cement pipe cement material needed The production process and cement pipe manufacturing process itself, serious environmental pollution, the environmental protection department has become the focus of management objects. Secondly, waste plastic pipe can be recycled. When combusted, produces only carbon dioxide and water vapor, no other harmful emissions. 6. No leakage: advanced structure, strip and strip joints uniform firm, a section of pipe has done a good seal. 7. The pipe wall thickness uniform, consistent performance: As the uniform (non-corrugated) SN8 hollow wall winding pipe wall thickness, so there is no weak link, and therefore uniform wall performance. 8. Easy installation: Due to the structure of the inner and outer walls of the double flat, tube and pipe, adopt socket link between the tube and the inspection well, easy installation, installation speed.
