In 2002, by taking advantage of an imported pipe bender form Italy, our company successfully developed 16 sets of pipe benders with various specifications: four sets with a diameter of Ф219—Ф508, three sets Ф323－Ф508, three sets Ф457－Ф813, two sets Ф813－Ф1016 and four setsФ864－Ф1270. Before the end of 2007, all the pipe benders were used by our own for pipeline work in Pearl River Delta, Guizhou Province, Shandong and Anhui Province and also in the project of Gas Transmission from Sichuan Province to the East.

Since 2008, our company has started sales, 2 sets to Liaohe Petroleum Construction Company, 1 set to Jianghan Petroleum Construction Company and 1 set to Changqing Oilfield.
