Steel belt reinforced polyethylene spiral corrugated pipe is a kind of wound structure wall pipe with high density polyethylene (.PE) as the base (inner and outer layers) and surface coating. Bonded resin steel strip composite. The pipe wall structure consists of three layers: the inner layer is a continuous solid-walled PE inner layer pipe, the inner layer pipe is wound with an annular corrugated steel belt reinforcement (formed with steel plate as "V" type), and the corrugated steel belt reinforcement is compounded with an outer layer of polyethylene outside the body, so as to form a whole spiral corrugated pipe. The elastic modulus of steel is nearly 200 times that of polyethylene (the elastic modulus of carbon steel is about 190000MPa). Combining the advantages of metal and plastic is obviously an ideal way to achieve high stiffness and low consumption. The excellent characteristics of corrosion resistance, wear resistance and flexibility of plastics are organically combined to give full play to the advantages of both aspects, make up for the shortcomings of both aspects, and achieve high performance and low cost.

The steel belt reinforced spiral corrugated pipe combines the advantages of steel and plastic very well. The steel bars pressed into a similar "U" shape with continuous steel strips are wound between the inner and outer layers of hot-welded polyethylene, which combines the high steel and high strength of the steel. Combined with the flexibility, corrosion resistance and wear resistance of polyethylene, the pipe can reach the three levels of ring stiffness of SN8, SN12.5, and SN16, which solves the corrosion resistance of steel. The larger diameter all-plastic buried drain pipe ring can generally only reach the limit of SN8.

Product specification: execution standard CJ/T225-2006 (Q/12JC3228-2006)

Performance Features:

1: Pressure resistance and impact resistance: The pipe adopts advanced plastic-steel forming and compounding technology, which enables the pipe to be reliably compounded, enhances the performance of the pipe, improves the performance of the pipe, increases the stiffness of the pipe ring (above SN10), has good strength and impact resistance, has good adaptability to any foundation;

2: Chemical resistance: will not be corroded by sewage, wastewater and chemicals, will not be corroded by decaying substances in the soil, and will not be damaged by plant roots;

3: Aging resistance: The pipe is generally black and can withstand the direct sunlight during stacking and construction;

4: Superior wear resistance: wear resistance than steel pipe, cast iron pipe and cement pipe;

5: The drainage flow is superior: the flow resistance of the inner wall of the pipe is small, the drainage speed is fast, the water flow capacity is strong, and the flow rate is large.

Connection method:

1. Electric hot melt belt welding

The high-temperature connection method generated by the electric heating element embedded in the contact surface of the connection is a rigid connection. Electric hot melt belt welding structure: it adopts a polyethylene electric melt belt with electric male wire embedded in the inner wall, which is close to the outer surface of the two connected ends (covering more than two centimeters of seam), and then fastened with a heat-resistant belt; at the same time, after the inner wall of the pipe end at the interface is firmly supported by a removable tool, the electric hot melt welding machine resistance wire is used for power supply. The resistance wire heats up and melts to form a pressure. The polyethylene on both sides of the interface diffuses with each other, turns off the power supply, and waits for sufficient cooling and curing to form a reliable connection.

2. Heat shrinkable belt connection

The fiber reinforced polyethylene heat shrinkable tape is used as the inner layer, the heat shrinkable tube is used as the outer layer, and the inner surface of the heat shrinkable tape is coated with hot melt adhesive.
