Q355B Seamless Steel Pipes Factory Pipes Hot rolled 60mm OD 10mm Thickness JIS SUS
In the 1930s, the quality of the steel pipe was improved due to the use of a three-roll mill, an extruder, and a periodic cold-rolled pipe mill. In the 1960s, due to the improvement of continuous rolling mills, the emergence of three-roller punching machines, especially the application of tension reducing machines and continuous casting blanks, increased production efficiency and enhanced the ability of seamless pipes to compete with welded pipes.
