Using high-density polyethylene as the base, a steel strip coated with adhesive resin on the surface is formed into a corrugated shape as the main support structure, and is wound and compounded with the polyethylene material to form an integral double-walled spiral corrugated pipe. Shandong Yanggu Dasheng Pipe Industry specializes in manufacturing steel belt-reinforced polyethylene spiral corrugated pipes for underground drainage. The continuous steel belt is pressed into an approximately ^-shaped spiral steel rib and wound between the inner and outer layers of heat-welded polyethylene to combine the high rigidity and High strength combined with the flexibility, corrosion resistance and wear resistance of polyethylene.
Requirements
_ Edit
) Applicable to medium whose long-term temperature is not greater than ℃.
) Buried plastic drainage pipes should be designed according to the theory of flexible pipes (the pipe and soil work together). At the same time, the change in the vertical direction of the pipeline under the design condition shall not be greater than the diameter of the pipe.
) The selection of pipe ring stiffness is an important indicator in the design of plastic pipes, so it should be determined based on comprehensive considerations such as pipeline burial depth, ground load, properties and compaction coefficient of trench backfill soil, and construction load. Blindly adopting high ring stiffness is uneconomical. If the roadway is buried deeper than the pipeline, the impact of pipeline deformation on the road surface should also be considered.
) Appearance
The inner surface of the pipe should be smooth, and the external corrugation should be regular. The inner and outer walls of the pipe should be free of bubbles and visible impurities, and the welds should not be detached.
The cross section of the pipe after cutting should be trimmed without burrs.
The incisions of the steel strips at both ends of the pipe should be on the same longitudinal line of the pipe.
