Precision steel pipe process and maintenance methods

Most people subconsciously think that precision steel pipes are not easy to rust because of their precision. To be honest, the corrosion resistance of precision steel pipes is very good, so its cost performance is relatively high, because there are layers of transition films on its surface, which can reduce the probability of being oxidized by air.

However, due to the excessive indulgence of people for precision steel pipes, it is not easy to care about the maintenance of precision steel pipes. However, the description of precision steel pipe shows that the weaker corrosion resistance part of the transition film will produce point corrosion reaction due to self-excited reaction, and produce small holes, which will go to the close chloride ion to form a strong corrosive aqueous solution, accelerating rate of erosion. Coupled with the intergranular corrosion cracking inside the stainless steel plate, it will also damage the transition film on the surface of the stainless steel plate. Therefore, certain levels of cleaning and maintenance should be carried out on the surface of precision steel pipes to better extend the service life of precision steel pipes.

Compared with ordinary pipeline materials, precision steel pipes have a certain degree of development and perfection in the manufacturing process. After the raw materials enter the production line, ultrasonic waves will be used to inspect the entire board, from leveling and milling to Cutting and forming, from butt welding laser cutting to fixed inspection, every process is accurate, in order to ensure that the quality of this kind of pipeline material is solid, and at the same time, precision steel pipes must be carried out before they go on the stage. Inspection, pressure test, oiled laser engraving, etc., at the same time, nature can ensure the quality of precision steel pipes when they debut.

At present, most precision steel pipes use two different processes of cold drawing and hot rolling. Relatively speaking, the technology of cold rolling will be more complicated. Carry out three-roll continuous rolling, and sizing inspection must be carried out after extrusion, which can better ensure the quality of hardware machinery pipeline raw materials. It is still very good in appearance.
