A brief history of seamless pipe
Date:2020-03-25      Views:95Time      Label:A brief history of seamless pipe

Production of seamless steel pipes has a history of nearly 100 years. The German Manismann brothers first invented the two-roll oblique rolling piercing machine in 1885, the cycle tube rolling machine in 1891, and R.C.Stiefel from Switzerland invented the automatic tube rolling machine (also known as the head tube rolling machine) in 1903. Later, various extension machines such as continuous pipe rolling mills and pipe jacking machines appeared, and the modern seamless steel pipe industry began to form. In the 1930s, due to the use of three-roll tube mills, extruders, and periodic cold-rolled mills, the quality of steel pipes was improved. In the 1960s, due to the improvement of the continuous rolling mill, the emergence of the three-roller perforator, especially the success of the application of the tension reducer and the continuous casting slab, improved the production efficiency and enhanced the ability of seamless pipes to compete with welded pipes. In the 1970s, seamless pipes and welded pipes were keeping pace, and the world's steel pipe output increased at a rate of more than 5% per year.

 

China attaches great importance to the development of seamless steel pipe industry after 1953, and has initially formed a production system for rolling various large, medium and small pipes. Copper pipes are also generally made by ingot blank piercing, pipe rolling, coil drawing.
