The superiority of spiral pipe in uses

According to the nature of doing HDPE plastic spiral coil, with a light texture, high strength, good toughness, easy to lay, water resistance, low cost, corrosion resistance, etc., its performance and economic benefits far exceed the reinforced concrete pipe and general specifications iron pipe, engineering pipe replacement products. In metallurgy, petrochemical and other industries exchanger design, there are various forms of heat, but the presence of a conventional heat exchanger ineffective, difficult to clean, fouling resistance and large more drawbacks, can not meet production of customer needs. According to the spiral knot spiral hose heat exchanger to do its good effect of heat transfer, easy to clean, low fouling resistance, compact structure and so on.

Plastic spiral steel pipe (also called hollow wall winding plastic tube) is a wall structure is very reasonable plastic tube. The overall use spiral structure. In for urban drainage projects, improve drainage capacity facility (or narrow diameter) and engineering service life, easy construction, shorten the construction period, when the water table is high, the depth of excavation and restoration of large or require high road, the project cost significantly reduced. Spiral has many superior heat transfer characteristics and structural features straight tube. Heat transfer coefficient is higher than the straight tubes, more heat transfer area can be obtained in the same space, the longer the pipe is arranged to reduce the seam to improve the safety. So spiral heat exchangers and steam generators in the field of power engineering, chemical, aerospace, and nuclear energy has been widely applied.

Large plastic spiral steel pipe is formed with a "T" shaped ribs with a sheet of polyvinyl chloride (UPVC) mixing the carbon black or high density polyethylene (HDPE) using a hot press method. Then on the volume of the machine roll cut into spiral. By quickly locking mechanical connection, the application of an adhesive or melted PVC reinforced molded plastic spiral. It has a large diameter, high corrosion resistance, good anti-leakage effects, quick construction and other characteristics.
