therefore, the cable protection pipe is gradually drawn to a hot-dip plastic steel pipe with more excellent performance, the hot-dip plastic steel pipe is prepared by uniformly coating polymer materials with different formulas on the metal surface through special equipment on the basis of surface treatment of a common steel pipe according to a used medium and working conditions, and forming a uniform, compact and smooth plastic coating on the metal surface after plasticizing and curing, so that the steel-plastic composite pipe becomes a novel steel-plastic composite pipe.

Most of cables in the cable protection pipe are wrapped by insulating plastic layers independently, but if the pipe diameter is too large or the number of cables in the pipe is large, electric charges are inevitably generated, once the pipe is exposed, potential safety hazards are easily caused, and the pipe are in rigid connection, so that the deformation resistance is poor.
