- Steel-plastic composite pipe is a new type of building water supply material. Because it can make the inner wall of the pipe corrosion-resistant and the outer steel pipe has high strength, it becomes a substitute for the whole plastic pipe and is recognized by the majority of users. The market is very good.
- the traditional steel-plastic composite pipe is manufactured by transferring heat to the plastic pipe through electric, oil, gas, natural gas heated steel pipes, and also directly bonding the plastic pipe of the inner liner to the steel pipe by using an adhesive (for example, the publication number is WO2004/011231). Patent literature).
- the traditional bonding is heated by electricity, oil, gas, natural gas, and converted into hot air to directly heat the pipe, which may cause uneven heating, resulting in poor bonding of the steel pipe or poor local adhesion. After thermal expansion and contraction, it is very It is easy to disengage steel and plastic, and it will lead to uneven steel-plastic end face and shrinkage of plastic pipe, which will not achieve the best quality of steel-plastic pipe.

The effect is excellent. Tests have shown that the steel-plastic composite pipe produced in this way has a markedly improved robustness and a prolonged life.
- Still another advantage of the present invention is that industrial waste steam can be utilized, which is advantageous for energy saving and reduction, and reduces production costs. Moreover, it will be readily understood by those skilled in the art that it is more economical to use steam heating than other direct heating or pressurization of the tubing by water or by water. Therefore, the invention enables the manufacture of the steel-plastic composite pipe to be combined with the numerical control equipment and the advanced conveying device, realizes the programming control and the man-machine dialogue, reduces the physical labor intensity through the high-tech, improves the production control precision and the product qualification rate, especially according to the pair.
