Description

Technical Field

[0002] Polymer composite pipes are also called steel-lined polymer material pipes. They are composite pipes made of multiple layers of materials. Generally, polymer material pipes are attached to the inner wall of metal pipes, so that the composite pipes have both the strength of metal pipes and various excellent properties of composite pipes, which are mainly reflected in stable chemical properties such as strong acid and alkali resistance, corrosion resistance, and aging resistance. There are generally two traditional processing methods. One is to prefabricate polymer material pipe fittings, and then install them on the inner wall of the metal pipe for integral sintering; the other is continuous sintering, which heats different positions of the metal pipe, and then adds polymer material to the inner wall in real time, and continues to sinter. Compared with the two processing methods, the latter is easier to intuitively control the sintering quality and flexibly adjust, but the feeding state of polymer materials is not easy to control, and the external heating of the metal pipe will have different thermal conductivity, resulting in uneven control of processing quality, and there are many disadvantages.
