(1) Raw materials are strip coils, welding wire, flux. Strict physical and chemical testing is required before input.
(2) The steel head and tail are butt jointed, and the single wire or double wir...
Seamless steel tubes are pided into hot-rolled (extruded) seamless steel tubes and cold drawn (rolled) seamless steel tubes due to their different manufacturing processes. Cold drawn (rolled) tubes ar...
The stainless steel tube does not easily rust and has a great relationship with the composition of the stainless steel. In addition to iron, stainless steel has chromium, nickel, aluminum, silicon, an...
Galvanized steel pipe has the advantages of corrosion resistance, long service life, and the price of galvanized steel pipe is correspondingly low, so its usage rate is now higher and higher. But when...
In the production of seamless steel tubes, regular holes and pits are mainly caused by uneven deformation. The key to solving the problem lies in reducing uneven deformation. In order to solve this pr...
