Abstract
Description
technical field
[0001] The patent of the invention relates to a steel-plastic winding composite pipe and its manufacturing device and manufacturing process. It is a large-diameter steel-plastic composite pipe, and the pipe is mainly used in the field of liquid transportation. Background technique
[0002] At present, polyethylene plastic pipes have been widely used in domestic water supply pipelines. The characteristics of this pipe are very prominent, with long service life and excellent corrosion resistance. In addition, no heavy metal salt stabilizers are added to polyethylene pipes during processing, and the material is non-toxic. In addition, it It will not promote the growth of algae, bacteria or fungi, which better solves the problem of secondary pollution of drinking water in cities and towns, and has good hygienic performance. Because it is an all-plastic pipe, when meeting the operating pressure and resisting external pressure (ring stiffness), the wall thickness o...
