And because the inner wall is smooth, the scale is not easy to form in the spiral winding pipe, and microorganisms are not easy to propagate. (2) The spirally wound high-density polyethylene pipe has high weld seam quality. (3) The high-density polyethylene is a high-molecular polymer, so that the spiral winding pipe has good flexibility and external pressure resistance. Even if the road surface with overload load condition is used, the traffic safety can be ensured. In geological activities such as earthquake and uneven ground settlement, the damage rate of the pipeline is low, and the earthquake and disaster resistance of public facilities is ensured. (4) The high-density polyethylene has good low-temperature resistance, the lowest use temperature is between 70 ℃ below zero and 100 ℃ below zero, and the polyethylene can be used in severe cold regions. (5) The high-density polyethylene has extremely strong corrosion resistance, chemical substance erosion resistance and aging resistance, and does not need to be subjected to anticorrosion treatment when conveying corrosive fluid or paving in severely corrosive soil. The service life can reach 50 years under the condition of not being irradiated by sunlight. (6) The high-density polyethylene spiral winding pipe is free of any additive in the processing process and is non-toxic. In the production process of the product, a cooling water circulation system is adopted, and no pollutant is generated. (7) The waste pipelines with the same mark can be recycled. In conclusion, the method is widely applied to municipal fields such as underground water supply, rain sewage discharge, underground cable protection and the like. In order to prevent sewage from seeping out of the joint and causing soil pollution, the connection between the pipe joint and the pipe is very important. In the prior art, the connection of the spirally wound pipes usually involves a plurality of complicated processes and depends on the experience of the operator. Therefore, a cold joint or a joint welding distortion is likely to occur at the wall thickness of the pipe, which seriously affects the connection quality, and this may cause leakage and cause environmental pollution.
