On April 10, Qilu Petrochemical Machinery Manufacturing Co., Ltd. undertook the manufacture of a forged welded wall thick container circulating hydrogen desulfurization tower, and the most critical welding difficulties were broken at one stroke. The qualified rate of four welding seams for 140 flaw detection sheets was 100. %.
The circulating hydrogen desulfurization tower is the core equipment of Tianjin Petrochemical's 1.2 million tons/year hydrocracking unit, which is 144 mm thick, 2 meters in diameter, 25 meters in total height and 161 tons in weight. This is the first forge welding container that the machinery manufacturing company assumed after becoming the national heavy-duty container manufacturer, and it is also the equipment with the largest wall thickness that they have ever produced. In order to overcome the welding difficulties, the engineering technicians in the workshop of Jinjie, a construction company, did not stick to the rules and repeatedly optimized the welding process. After many successful welding tests, the excellent welders Cui Mingli and Ji Zhaowei led the two construction teams to perform continuous welding for 24 hours. After 6 days and 6 nights of continuous fighting, the welding mission was successfully completed.
The successful welding of the circulating hydrogen desulfurization tower marks the new level of heavy-duty thick-walled container manufacturing of the machinery manufacturing company. It provides a strong product basis for the machinery manufacturing companies to participate in the competition of domestic and foreign heavy container markets.
