Abstract

The utility model discloses a steel reinforcing PE (Polyethylene) bellows and manufacturing equipment thereof. The bellows comprises a pipeline inner wall formed by spirally rolling a plastic plate band. The steel reinforcing PE bellows is characterized in that the outside of the pipeline inner wall is at least covered by a layer of steel mesh; the outside of the steel mesh is covered by a pipe wall polyethylene layer; a steel band is fixed on the polyethylene layer; and the outside of the steel band is covered by the polyethylene layer. The steel reinforcing PE bellows has the beneficial effects that: the pipeline is formed by spirally rolling the formed plate band and the pipe diameter can be produced to be greater; a larger of extruded plastic in the rolling process is avoided, so that the energy consumption is reduced; in addition, the capability of the pipeline of bearing the inner pressure is improved by using the steel mesh arranged in the pipe wall; the pipe wall polyethylene layer is relatively thinner; the capability of the pipeline of bearing the inner pressure is improved by using the externally-fixed steel mesh; and the manufacturing cost of the whole pipeline is low; the steel reinforcing PE bellow can be used as a water draining pipe or a water feeding pipe; and the pipeline resists corrosion and has a long service life.
