Q345B Seamless Steel Pipes Factory Use AISI SUS Bright Black 57mm OD 9mm Thickness
Seamless steel pipe production has a history of nearly 100 years. The German Mannesmann brothers first invented the two-roll cross-rolling piercing machine in 1885, and invented the cycle rolling mill in 1891. In 1903, the Swiss Ritteriefel invented the automatic pipe rolling machine (also called the head-rolling pipe). Machines, and later various types of extension machines such as continuous tube rolling mills and pipe jacking machines, began to form a modern seamless steel pipe industry.
