Plastic-coated steel pipe production process

Abstract

The invention relates to a plastic-coated steel pipe production process. The plastic-coated steel pipe production process uses a plastic-coated steel pipe production device. The plastic-coated steel pipe production device comprises a workbench, an internal cleaning mechanism and an external cleaning unit, wherein the workbench is arranged on the existing working ground, the internal cleaning mechanism is arranged at the upper end of the workbench, and the external cleaning unit is arranged at the right end of the internal cleaning mechanism. According to the plastic-coated steel pipe production process, plastic-coated steel pipes are produced by adopting the design concept of internal and external dual cleaning, the arranged internal cleaning mechanism can enable the pipe fittings to be subjected to internal cleaning under a limiting and fixing condition, and the stability degree of the pipe fittings in the cleaning process is kept, so that the purpose of improving the cleaning effect is achieved; and the internal cleaning mechanism and the external cleaning unit utilize magnetism to clear impurities generated by cleaning so that the probability that the impurities are attached to the inner surfaces and the outer surfaces of the pipe fittings again can be reduced, and meanwhile, the phenomenon that the impurities are accumulated inside the pipe fittings can be avoided.

Description

technical field [0001] The invention relates to the field of steel pipe processing, in particular to a production process for plastic-coated steel pipes. Background technique [0002] Plastic-coated steel pipes, also known as plastic-coated pipes, steel-plastic composite pipes, and plastic-coated composite steel pipes, use steel pipes as the substrate, and weld a layer of plastic anti-corrosion layer or Steel-plastic composite steel pipe with plastic anti-corrosion layer welded on the inner and outer surfaces. Before welding the plastic anti-corrosion layer, the inner surface of the pipe fitting needs to be polished and cleaned. Plastic-coated steel pipe has excellent corrosion resistance and relatively small frictional resistance. Epoxy Plastic-coated resin steel pipes are suitable for the transportation of media such as water supply and drainage, sea water, warm water, oil, and gas. PVC-coated steel pipes are suitable for the transportation of media such as drainage, sea w...

Problems solved by technology

[0003] 1. Common cleaning structures are mostly aimed at straight-through pipe fittings, but the cleaning force for curved pipe fittings is insufficient. At the same time, the impurities generated by scraping and cleaning the inner and outer surfaces of pipe fittings cannot be effectively treated in time, and the impurities inside the pipe fittings are also prone to reappear. the phenomenon of attachment;
