Jiangsu Xigang Commissions PQF® Mill from SMS Meer

05/18/2011 - Jiangsu Valin-Xigang Special Steel Co. Ltd., China, has commissioned its new PQF® (Premium Quality Finishing) seamless tube mill supplied by SMS Meer.

Jiangsu Valin-Xigang Special Steel Co. Ltd., China, has commissioned its new PQF® (Premium Quality Finishing) seamless tube mill supplied by SMS Meer. The mill will enable the company to reduce standstill times and hence increase the productivity at its works in Wuxi.
 
The new line’s annual capacity in future will be 500,000 tonnes, and its maximum tube diameter is 10 ¾ inches. It is built around a six-stand PQF mill of LCO (Lateral Change Over) design in which the stands are changed from the side, simplifying service and maintenance. The mill enables the productions of thin-walled tubes within close tolerances and requires less material and energy.
 
“The PQF® mill enables tubes to be produced with a higher quality, thus strengthening our position on the market,” says Lei Youtong of Jiangsu Valin-Xigang. The company will use the machine predominantly for the production of tubes for the oil and gas industry.
 
SMS Meer and SMS Innse supplied the core components of the rolling mill equipment for the new PQF line, including the CARTA® automation and quality assurance system. The scope also included a PQF calibration stand for checking the rolls and chocks after dressing. SMS Meer also was responsible for project management, supervision of erection supervision and commissioning, and hands-on training of the operating personnel.
 
The seamless tube plant at Jiangsu Valin-Xigang is the 11th PQF mill to be successfully put into operation. A further five such seamless tube mills will go into production during the course of 2011.
