stability of the welding process. The pipes are used among others for the nearby Shengli oilfield, the second-largest petroleum producing area in China. Shengli Oil & Gas Pipe Holdings Limited is one of the largest petroleum and natural gas pipeline manufacturers in China. The company is one of the major producers of spiral submerged arc welded pipe for PetroChina Group and Sinopec Group. Shengli has been producing such pipes for 35 years. The production facilities are located in Zibo City, Dezhou City and Rizhao City in Shandong Province, China.

WITHIN SMS Meer, PWS GmbH is responsible for special pipe machines and offers plants that are among the most modern in the world. For Shandong Shengli Steel Pipe Company, Rizhao City, Shandong Province, China, PWS is to supply a two- stage spiral pipe forming and welding plant with particularly high energy efficiency. After completion of the plant in September 2011, Shandong Shengli will produce 240,000 tons of spiral-welded pipes per year, which are mainly used for natural gas and petroleum pipelines. The pipes will have a diameter of up to 64" from high-alloy steels. PWS supplies an integrated plant consisting of a spiral pipe forming and tack-welding machine for forming and pre-welding of hot-rolled steel strip and downline finish-welding stands. In the future, Shandong Shengli will thus be able to produce high-quality pipes with diameters of 24 to 64" from high-alloy steels. Thanks to the technology from PWS the degree of energy yield during welding has reached a new record level. Michael Stark, managing director of PWS, said: “We believe in welding current sources without transformers and an advanced process control by power electronics. In this way, we achieve efficiencies of more than 90% resulting in an energy saving of more than 30% compared to the older technology.” Another benefit of modern technology: Shandong Shengli is able to increase the welding speed without compromising Orbital welding GULLCO Pipe Kat ® automated pipe welding system with integrated wire feeder unit incorporates 40 IPM welding carriage design with quick action mounting. The carriage is equipped with a high speed return feature for faster repositioning of the carriage. The Pipe Kat also comes equipped with a linear oscillator with adjustable weave width and weld joint centreline adjustment. The system comes with a main control box with 25ft (7,620mm) umbilical, wire feed spool capacity of 10lb (4.5kg), with a maximum wire speed of 35-633 IPM (89-226 cm/min) and a wire size range of 0.8 to 2mm.
