The steel strip pipe produced by the steel strip pipe manufacturer is a double-walled spiral bellows with high-density polyethylene as the matrix, and the steel strip coated with adhesive resin is formed as the main support structure, and is wound and compounded with polyethylene material to form a whole double-walled spiral corrugated pipe. It is suitable for the long-term temperature of the medium is not more than 45°C. Buried plastic drainage pipes should be designed according to the theory of flexible pipes. At the same time, the change in the vertical direction of the pipeline in the design state shall not be greater than 5% of the pipe diameter.

The inner surface of the steel strip pipe produced by the steel strip pipe manufacturer is smooth, and the external waveform should be regular; The inner and outer walls of the pipe should be free of bubbles and visible magazines, and the weld joints should not be disengaged. The steel strip pipe manufacturer should have a flat section without burrs after cutting the pipe, and the steel strip incision at both ends of the pipe should be in the same longitudinal line of the pipe.

The raw materials used in the production of pipes by steel strip pipe manufacturers should be mainly polyethylene resin, which can only add additives necessary to improve performance, and the content of polyethylene should be more than 90%.

The selection of the ring stiffness of steel strip pipe is an important index of plastic pipe design, so it should be determined that it is uneconomical to blindly adopt high ring stiffness from the comprehensive consideration of pipeline burial depth, ground load, the nature and compaction coefficient of trench backfill and construction load. For pipelines with a buried depth of less than 1.0m under the roadway, the influence of pipeline deformation and road surface should also be considered.
