Square Tube Production Process
(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...
Classification of Seamless Steel Tubes
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...
Does the Stainless Steel Tube Must not Rust?
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...
Welding Characteristics and Process of Galvanized Steel Pipe
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...
How to Deal with Pit and Hole Defects in Hot-rolled Seamless Steel Tubes?
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...
Application of Seamless Steel Pipe in Transportation
There are now more and more types of vehicles, and seamless steel tubes play an important role in the manufacture of vehicles. For example, the application of seamless steel pipe in vehicles mainly re...
How to Make the Seamless Steel Pipe Last Longer?
The seamless steel pipe is expressed by the method of outer diameter, wall thickness and thick-walled seamless pipe, which are mainly used for mechanical processing, coal mine, hydraulic steel and the...
Mechanical Properties of Steel
The seamless steel pipe is a steel pipe without weld seams produced by a perforated hot rolling method. It is sometimes necessary to further cold work the hot worked tube in order to obtain the corres...
Seamless Steel Tube Bending and Straightening
The seamless steel tube is bent because the rolling mill is not properly adjusted, the residual stress remaining during rolling, and the unequal cooling due to the cross-section and length of the tube...
Causes of Small-diameter Seamless Steel Pipe Rust and How to Deal With It
Seamless steel pipes are widely used in our lives and are also suitable for all major factories, so the specifications and specifications are very high, especially the outer diameter of seamless steel...
