On the morning of June 30, a large-diameter hydrostatic testing machine with a diameter of 3 meters was successfully tested at Taojiang Xinxing Fittings Co., Ltd., located in the Taojiang Economic Development Zone. It is understood that this is the first set of large-diameter hydrotesting machines in China, capable of handling diameters of 3 meters, and it has been successfully tested. In the hydrotesting section of the finishing workshop, workers are assembling a pipe fitting with a diameter of 3 meters along with two testing fixtures to prepare for the hydrotest. At around 11 a.m., water injection for pressure increase began. After a half-hour process of pressurization by water injection, at 11:30 the pressure reached 35 kilograms. After maintaining this pressure for one minute, no leaks were detected in the piping, and the hydraulic press operated normally, marking the successful trial run of China’s first large-diameter hydraulic testing machine developed independently by this company. For a long time, pipe fittings with a diameter of over 2.6 meters have been unable to undergo hydraulic testing in factories using automated equipment; manual operation has had to be used instead, resulting in long processing times, low efficiency, and high labor intensity for workers. Cui Jinzhong, assistant to the general manager of the company, said, “The successful testing of this set of equipment has solved the problem of conducting hydraulic tests on large-diameter pipe fittings over 2.6 meters in diameter using such equipment. It has improved the company’s level of professional equipment, and it also provides a solid logistical foundation for large-scale water diversion projects and for gaining a foothold in the international cast pipe market.” ” Taoyang Xinxing Fittings is a wholly-owned subsidiary of Xinxing Cast Pipe Co., Ltd. The company specializes in the production of ductile iron fittings, which, thanks to their high strength, good toughness, resistance to high pressures, and corrosion resistance, are widely used in areas such as water, oil, and gas transportation, as well as in the pressurized transport of various liquids and gases. Its products are sold to 58 countries and regions across Europe, America, Africa, and the Middle East, with an export ratio of 25%–45%.
