Supply large-scale pipe fittings processing, ship pipeline processing, and flange welding followed by bending processing. Provide you with boilers and suppliesPrecision bending of large-diameter pipelines for ships, welding and bending of flanges for boilers and marine pipelines. Large diameter pipelines are widely used in fields such as boilers, ships, marine engineering, and chemical engineering. Known as the 'bloodline' of industry. It is used to connect various mechanical equipment and transmit working fluids such as water, oil, and gas. According to market research, steel pipe usage accounts for about 7% in the shipbuilding process, and ship pipe processing accounts for 8-10% of the total shipbuilding work. Among them, the demand for specifications with an outer diameter of 273mm or more accounts for between 10% and 15% of the total steel pipe demand. According to data from China's shipbuilding industry in 2012, the consumption of steel pipes was approximately 1.686 million tons, of which 170000 to 250000 tons were used for specifications with an outer diameter of 273mm or more. The annual processing output of the pipe processing workshop has expanded from 100000 to 150000 pipes to 200000 to 300000 pipes, with some enterprises reaching an annual output of 500000 to 700000 pipes. At present, although domestic pipeline processing temporarily meets the needs of shipbuilding, there are still phenomena such as low production efficiency, high cost, and poor quality. In addition, the utilization rate of pipe materials is low, and a large amount of energy is consumed. Pipeline processing is still rough production. China's shipbuilding industry undertakes a large number of high-tech, high value-added ships and various marine engineering projects. The requirements for pipeline processing are becoming increasingly high, and the processing quality is receiving more and more attention from ship owners, ship inspection departments, and shipbuilding enterprises. Throughout the research of scholars and research institutions at home and abroad on the cold bending forming technology of large-diameter pipelines, there has been no mention of the impact of steel pipe cold bending on material properties. However, in practical applications, material properties are crucial. Therefore, it is necessary to thoroughly study the specific impact of steel pipe bending on material properties, which is the technical key to expanding the application of large-diameter pipeline cold bending forming technology in manufacturing. In this project, we will propose for the first time to study the effects of relative bending radius, bending speed, and pipe diameter size on material properties, and establish corresponding mathematical models to describe the changes in material properties during the bending process. Provide theoretical support for the development of cold bending processing technology for large-diameter pipelines.Due to the technical particularity of bending pipe processing, both parties need to carefully discuss and communicate.
