OREANDA-NEWS. June 16, 2014. MCC Baosteel Technology Services Co., Ltd. (BTS) received the utility model patent certificate awarded by the State Intellectual Property Office (SIPO) for the Submerged-arc Welding Wires Barrel-type Feeding Machine.

Therefore BTS becomes the first Chinese enterprise which has mastered the manufacturing and applying technologies of one-ton Submerged-arc Welding Wires Barrel-type Feeding Machine, and has filled the domestic void in this field. The performance indicators of the machine have been proved to be of worldwide advanced level.

It is reported that, with regard to the welding wire feeding machines produced by most of the domestic manufacturers, the weight of the one-time filled welding wires is around 200-300kg, and the length of the continuous direction is about 2,000-3,000m. As for the feeding machines produced by BTS, such weight and length are respectively rated at one ton and 10,000m, about 3-4 times of those domestic normal machines. The newly developed equipment will ensure the continuous welding operation of the steel pipe, reduce the changing times of the welding wires, and increase the operative efficiency by 15% especially during the operations of the multi-wire spiral welded pipe and the longitudinal welded pipe.

Now the Submerged-arc Welding Wires Barrel-type Feeding Machine has been widely utilized by domestic steel pipe manufacturers such as Baosteel’s Pipe Plant (Longitudinal Welded Pipe), Shanghai Zhongyou Tianbao Steel Pipe Company, Hebei Julong Steel Pipe Company and Shandong Shengli Steel Pipe Company. The performance of the machine has been placed with high premium by all the clients.
