In recent years, the demand for steel pipe insulation pipes in various domestic industries has increased. The production technology of domestic steel pipe anti-corrosion factories has been relatively mature, and all kinds of anti-corrosion can be produced. Among them, 3PE anti-corrosion steel pipes have outstanding performance advantages. Sales of spiral steel pipes The equipment usually used in the production of anti-corrosion and insulated steel pipes include pipe buffer platforms, pipe pulling units, tractors, pipe penetration machinery, high-pressure firing machines, repair platforms, transmission lines, steel pipe preheating furnaces, and shot blasting machine hosts. and other equipment. 3PE anti-corrosion steel pipes should be applied to the inspection bench and unqualified steel pipes return transmission lines during the inspection. The application of these can not only provide good insulation steel pipes, but also the product quality has passed strict testing.

The specific production process of anti-corrosion steel pipes is to first inspect the anti-corrosion steel pipes and then inspect the steel pipes based on various conditions to make them meet the conditions for making insulated steel pipes. Check whether the steel pipe is corroded, and check and remove the embroidery on the steel pipe. The next step is to put the rust-removed and anti-corrosion steel pipe into a polyethylene casing to form the pipe. Then after repairing the head, polyurethane foam is injected inside to fill the gaps so that they are filled. Inspect anti-corrosion steel pipes, and conduct finished product inspection on completed insulated steel pipes.
