Since it is not possible to achieve the accuracy with which the contact strips just abut against the inside of the outer tube during assembly, the above-mentioned gap can be filled by means of a filling glue. The process difficulty is effectively reduced.
In the above high pressure-resistant corrosion-resistant polypropylene pipe, the filling adhesive is an epoxy resin adhesive.
In the high-pressure-resistant corrosion-resistant polypropylene pipe, the filling adhesive is a polyurethane sealant.
In the high-pressure-resistant corrosion-resistant polypropylene pipe, the side part of the outer pipe is provided with a notch which penetrates through the outer pipe, the two sides of the notch of the outer pipe are respectively a first connecting side and a second connecting side, and the first connecting side is in contact with the two surfaces of the first connecting side and is fixedly connected with the two surfaces of the second connecting side through heat sealing.
When the inner pipe is completely coated by the outer pipe, the two sides of the C-shaped outer pipe are connected together by the existing heat sealing process, and the formed cylindrical outer pipe can stably coat the inner pipe.
Compared with the prior art, the high-pressure-resistant corrosion-resistant polypropylene pipe has the advantages that the outer pipe and the inner pipe are stably connected together under the action of the connecting strip and the contact strip, so that the stability is higher.
The gap between the outer pipe and the inner pipe is effectively eliminated under the action of the filling glue, so that the stability of the pipe is further improved, and the strength of the whole pipe is also properly improved.
In addition, because the connecting strip and the contact strip are positioned between the outer pipe and the inner pipe, the structure is compact, and the practical value is high.
