The Evolution of Seamless Pipe Technology
The production of seamless steel pipes has a history of nearly 00 years. The journey began in 85 when a Scottish inventor used steel pipes to convey gas for lights.To get more news about

Early Developments
In 86, the United Kingdom patented the production of seamless steel pipes by the extrusion method. However, it was not until 885 that the German Mannismann brothers invented the process of directly producing seamless pipes from bar steel.
Technological Advancements
The Mannismann brothers invented the roll cross-rolling piercing machine in 885 and the periodic tube rolling machine in 89. In 90, Swiss R Stiefel invented the automatic tube rolling machine. These inventions began to form the modern seamless steel pipe industry.
Welded Pipes
In terms of welded pipes, patents were obtained in 9. After low-frequency resistance welding and DC welding, it has now entered the era of high-frequency induction welding mainly used for the production of medium and small diameter steel pipes.
Modern Developments
In the 90s, seamless steel pipes adopted three-roll mills, extruders, and periodic cold-rolled pipe mills, which improved the variety and quality of steel pipes. In the 960s, due to the improvement of the continuous rolling 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 competitiveness of seamless steel pipes and welded pipes.
Current Scenario
In the 970s, seamless steel pipes and welded pipes went hand in hand, and the world’s steel pipe production was increasing at an annual rate of more than 5%. After 95, China attached great importance to the development of seamless steel pipe industry, and has initially formed a production system for rolling various large, medium and small pipes.
In conclusion, seamless pipe technology has evolved significantly over time. From its humble beginnings to its current state-of-the-art manufacturing processes, it continues to play a crucial role in various industries.
