Product Details

semco spiral pipe fittings Seamless steel pipe production has a history of nearly 100 years.In 1885, German mannesmann brothers first invented the two-roll cross mill piercing machine. In 1891, they invented the cycle mill. In 1903, the Swiss r.c.stiefel invented the automatic pipe rolling machine (also known as the top mill).In the 1930s, due to the adoption of three-roller pipe rolling mill, extrusion mill and cycle cold rolling mill, the quality of steel pipe varieties was improved.In the 1960s, due to the improvement of continuous mill, the emergence of three-roll punch, especially the application of tension reducer and the success of continuous casting billet, improved the production efficiency and enhanced the ability of seamless pipe to compete with welded pipe.
