Production technology of steel band-enhanced polyethylene screw corrugated pipe

Abstract

The invention discloses a production technology of a steel band-enhanced polyethylene screw corrugated pipe. The technology comprises the following steps: (1) inspecting raw materials; (2) carrying out plastic coating treatment on a steel band; (3) carrying out forming bending treatment on the steel band subjected to plastic coating treatment in the step (2), wherein the bent shape is a V shape; (4) winding a sheet extruded from dried polyethylene resin to form a core layer band, winding the steel band formed and bent in the step (3) on the core layer band according to preset screw pitches, covering the steel band with a polyethylene resin layer through extrusion to form an outer layer band, and finishing bonding and compounding of the core layer band and the plastic-coated steel band, and the plastic-coated steel band and the outer layer belt by a thermal fusion welding technology to form a pipe tube with an overall structure; and (5) carrying out length-measuring cutting after cooling and sizing and warehousing the product after qualified inspection. According to the production technology, by reasonably controlling the production process and reasonably setting parameters, the produced pipe can be spliced firmly and the layering problem is solved.

Description

technical field [0001] The invention relates to a production process of a steel strip reinforced polyethylene spiral corrugated pipe, belonging to the field of steel strip reinforced polyethylene spiral corrugated pipes. Background technique [0002] Steel belt reinforced polyethylene spiral corrugated pipe is a new type of clinker buried drainage pipe. It uses continuous steel belt to press into a V-shaped cross-section and then spirally winds it between the inner and outer layers of thermally welded polyethylene. High rigidity, high strength and the flexibility, corrosion resistance and wear resistance of polyethylene are combined together. [0003] Due to the lack of process control or unreasonable parameter setting in the production process of the existing production process, it is difficult to form the pipe and it is easy to break, the bonding is not strong, and the problem of delamination is easy to occur. There are certain safety hazards during installation and use. ...
