At present, the most widely used spiral steel pipe material on the market is Q235B, mainly because Q235B material is relatively affordable and its performance is suitable for many industries, but in some special industries, high-performance materials such as Q345 and L360 are also used. The main materials of the spiral steel pipe are: Q235A, […]
It can be said that more and more industrial enterprises will use seamless steel pipes, and some enterprises have also found that in the process of using such pipes, there may be a situation of corrosion sometimes. Relevant persons in charge also want to know why such a situation occurs. And if it is transported […]
Classification of national standard seamless steel pipes: seamless steel pipes are divided into two categories: hot-rolled and cold-rolled (dial) seamless steel pipes. Hot-rolled seamless steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel […]
Why do we need to blow borax in the production process of seamless steel pipe? What is the process and purpose? The limit mandrel continuous rolling mill has one more process than the floating and semi-floating mill. Oxidizer, whose technological purpose is to remove iron oxide scale on the inner surface and prevent secondary oxidation. […]
Precision bright seamless steel pipe is a kind of high-precision steel pipe material processed by fine drawing or cold rolling. Due to the advantages of no oxide layer on the inner and outer walls of the precision bright tube, no leakage under high pressure, high precision, high finish, no deformation in cold bending, no flaring, […]
The dredging spiral steel pipe adopts the technology of submerged arc welding, also called submerged arc welded straight seam steel pipe. The main function is to clean up the steel pipes that transport sediment, mud and other mixed debris. The purpose is to excavate port basins, access channels, etc., reclamation and reclamation to build wharfs, […]
