Introduction of double flat wall steel-plastic composite drainage pipe

The double-flat wall steel-plastic composite winding drainage pipe developed and produced recently by Jingzhou Liangcheng Science and Technology Co., Ltd. is prefabricated into "T" type plate belt with high density polyethylene (HDPE) as the main raw material. The plate belt is wound on the pipe forming machine and welded into a pipe. At the same time, the W-type steel belt bound by galvanized steel belt is embedded in the groove between the two plates, and PE is coated on the steel belt to become the third generation of new steel-plastic drainage pipe on the outer wall of the pipe.

Product Description

HDPE double-flat wall steel-plastic composite drainage pipe has both the corrosion resistance of plastic and the strength and toughness of steel, so its advantages are obvious; It is characterized by high ring stiffness, safety and reliability, light weight, simple installation, good sealing, low transportation and construction costs, strong corrosion resistance, and strong resistance to abnormal sudden load.

Product Features

1. High ring stiffness: after testing and engineering use, the ring stiffness is greater than SN8, and the maximum can reach SN16.

2. Good corrosion resistance: HDPE has excellent corrosion resistance. The profiled steel after anti-corrosion treatment is completely buried in HDPE, and the service life of the pipeline is more than 50 years.

3. No leakage: advanced structure, advanced voltage fusion between plates and strips, uniform and firm joints.

4. The pipe wall thickness is uniform and the performance is consistent: because the pipe wall thickness is uniform (non corrugated) and there is no weak link, the pipe wall thickness performance is consistent.

5. Convenient installation: due to the double-flat structure of the inner and outer walls, the socket connection is adopted between the pipe and the pipe, and between the pipe and the inspection, which is convenient for installation and fast for installation.

6. The overall cost of the project is low: for large-diameter pipes, considering the manufacturing cost, transportation and installation cost savings, the comprehensive cost of the double-flat wall steel-plastic composite drainage pipe project is lower than that of other types of pipes except cement pipes. Compared with cement pipes, because the inner wall of plastic pipes is smooth and flat, plastic pipes with the same diameter as cement pipes can transport larger media flow (about 15%), Therefore, the comprehensive cost of double-flat wall steel-plastic composite drainage pipe is slightly lower than or equal to that of cement pipe, but its service life is greatly extended.

7. Resistance to formation settlement: Due to the advanced structure design of the pipe wall and the reasonable process design, the buried double-flat wall steel-plastic winding drainage pipe has both rigid and flexible performance. Our extremely harsh destructive experiments have proved that the buried double-flat wall steel-plastic winding drainage pipe can resist the harsh environment and the formation settlement.
