Description
Technical field
The present invention relates to a kind of plastic composite pipe, especially relate to a kind of multi-lay winding composite pipe, belong to plastic composite pipe design field.
Background technique
The exploitation of plastic tube and applying the time that has decades, the plurality of advantages such as plastic tube is corrosion-resistant, wear-resistant with it, wholesomeness, circulation are good, energy-conserving and environment-protective have obtained using widely.In recent years the improvement of plastic tube performance and structure has been obtained people in the industry's attention, a large amount of composite metal plastic pipes continue to bring out, and wherein steel wire mesh frame plastic (polyethylene) composite pipe is the most typical.
Fig. 1 is the structural representation of existing steel wire mesh frame plastic composite tube; Fig. 2 is the steel wire arranging distribution map of enhancement layer in Fig. 1.
