Production Process and Other Introduction of Steel Strip Reinforced Spiral Corrugated Pipe



Number of views:

  Steel belt reinforced spiral corrugated pipeThe specific production process: first coil a solid wall PE inner pipe on the main machine, then stack the steel plate reinforcement layer into an inverted "U" shape and coat it with adhesive resin with excellent performance. In the design part of the solid wall PE inner pipe, a PE surface layer with the same waveform as the steel plate reinforcing rib is extruded from the outside, and the finished pipe is obtained after shaping, shaping, cooling and laser cutting. Then, let's learn about it together.Steel belt reinforced spiral corrugated pipeThe production process and other introduction!


Municipal road works: buried drainage pipeline, sewage pipeline

Sports venues: golf driving range, football field and other sports venues leak drainage pipe

Water conservancy project construction: use of water source pipe, irrigation pipe and drainage pipe of hydropower station

Mine workshop: mine ventilation, air supply, drainage pipeline, mud pipeline

Municipal road engineering: railway line, highway seepage drainage pipe

Industrial production: generally used in industrial production industry sewage pipeline

Engineering construction: building rainwater pipes, underground drainage pipes, sewage pipes, ventilation pipes, etc.; garbage disposal sewage collection pipes

Large and medium-sized seaports and port engineering projects: large and medium-sized airports, seaports and port engineering projects are reinforced with steel belts for drainage pipes and sewage pipes.Steel belt reinforced spiral corrugated pipeProvisions:

1. Laying: before the subbase construction of subgrade engineering unit, the horizontal middle belt drainage pipe shall be laid.

2. Grooving: Manual slotting shall be carried out according to the design chainage set by the construction drawing design and on-site measurement by the surveying personnel.

3. Docking: The sockets on both sides of each steel belt reinforced polyethylene spiral corrugated pipe need to be sleeved with rubber rings and tightened to avoid water leakage.

4. Lower pipe: clean the bottom of the water tank, connect the upper pipe according to the length of the water tank, put the water pipe into the water tank, and tie one end of the belt edge with linen cloth in the middle to prevent dirt from entering the pipe and causing blockage.

5. Backfilling: Select excavated fine-grained soil for backfilling, or sand for backfilling. Be sure to remove the large gravel. Manual compaction is required after backfilling. The top of the backfill shall not be higher than the subgrade and shall be lower than the subgrade. Surface 1~2cm is appropriate

6. Cleaning: The residual soil after backfilling shall be removed immediately and the ground shall be cleaned. The residual soil of HDPE pipe shall be unloaded in specific places such as borrow yard, and shall not be unloaded on the road at will.

steel reinforced spiral corrugated pipe provisions:

1. The long-term temperature of the applicable medium shall not exceed 45.

2, buried plastic drainage pipe should be designed according to the theory of flexible pipe. In addition, under the design conditions, the vertical direction of the pipeline should not change more than 5% of the pipe diameter.

  3、Steel belt reinforced spiral corrugated pipeThe selection of the specified ring stiffness is a key index value in the design of plastic pipes. Therefore, the characteristics of pipeline burial depth, ground load, trench backfill, compaction coefficient and engineering construction load should be considered comprehensively. and other comprehensive considerations. It is uneconomical to blindly follow the trend and choose high ring stiffness. For pipelines buried below 1.0m below the roadway, the interference of pipeline deformation to the ground should also be considered.
