Compared with ordinary pipe materials, the manufacturing process of precision steel pipes has been developed and improved to a certain extent. After the materials enter the production line, ultrasonic waves will be used for full-board inspection, from leveling and milling, to shear forming, from correcting From welding and cutting to visual inspection, we strive to be precise in every step, in order to ensure that the quality of this kind of pipe material is excellent. At the same time, before going out, the precision steel pipe also needs to undergo necessary tests, pressure test, oiling and marking Wait, in this way, the quality of the precision steel pipe can be guaranteed naturally.

At present, most precision steel pipes use two different processes: cold drawing and hot rolling. Relatively speaking, cold rolling is a more complicated production technology. Not only does the tube blank need to be rolled with three rolls , After extrusion, a sizing test must be carried out, so as to better ensure the quality of precision pipe materials. Precision steel pipes manufactured with excellent technology are good in quality and appearance.
