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.

both internal welding and external welding are performed by using Lincoln welding machine in the United States for single wire or double wire submerged arc welding, and then stable welding standards are obtained. select the weld gap control equipment to ensure that the weld gap is satisfied with the welding requirements, the pipe diameter, the amount of wrong side and the gap are strictly controlled.
the welded welds were all inspected by online continuous ultrasonic active flaw detector, ensuring 100% coverage of nondestructive testing of spiral steel tubes.If there are shortcomings, alarm and spray mark, production workers according to this at any time to adjust the process parameters, eliminate the shortcomings in time.
