The production of seamless steel pipes has a history of nearly 100 years. The German Manismann brothers first invented the two-roll cross-rolling piercing machine in 1885 and invented the periodic tube rolling the machine in 1891. In 1903, the Swiss R Stiefel invented the automatic tube rolling machine. After that, the continuous tube rolling machine and the top machine appeared. Various extension machines such as pipe machines began to form the modern seamless steel pipe industry.

In the 1930s, the use of three-roll pipe rolling mills, extruders, and periodic cold rolling mills improved the variety and quality of steel pipes. In the 1960s, due to the improvement of the continuous tube mill, the emergence of the three-roll piercing machine, especially the success of the application of the tension reducer and the continuous casting billet, improved production efficiency and enhanced the ability of seamless pipes to compete with welded pipes. In the 1970s, seamless pipes and welded pipes went hand in hand, and the world's steel pipe production increased at an annual rate of more than 5%.

After 1953, China attached great importance to the development of the seamless steel pipe industry and has initially formed a production system for rolling various large, medium and small pipes.

The stainless steel seamless pipe produced by Huzhou Nanxun Yintuo Special Material Technology Co., Ltd. has been favored by a large number of customers because of its high quality and good service. If you need to purchase related seamless steel pipe products, please contact us.
