The invention provides a corrugated steel pressure pipeline welding and sealing method, which belongs to the technical field of corrugated pipes. Conical pins are used to fix each connecting plate; then multiple ring structures are temporarily fixed with bolts, and then the installation dimensions between the two ring structures are checked to see if they meet the standard. form the bellows; finally, the butt joints of the first flange and the second flange are welded and sealed. The corrugated steel pressure pipeline welding and sealing method provided by the present invention improves the shear resistance of the bellows with the help of conical pins, and can carry Higher water pressure, and temporarily fixed by bolts, not only facilitates the use of tapered pins for later fixing, but also facilitates the inspection of the installation of the bellows. At the same time, the use of welding seals enables the bellows to withstand higher water pressure .
Description
technical field [0001] The invention belongs to the technical field of corrugated pipes, and more specifically relates to a method for welding and sealing corrugated steel pressure pipes. Background technique [0002] The corrugated steel plate is light in weight, can withstand large pressure loads, and is prefabricated in a factory, which can realize standardized production and processing, and is a good building structural material. The current installation of corrugated steel pipes relies on bolted connections, and gaskets are provided at the joints of the connecting plates, which can achieve low-pressure waterproof sealing, but the sealing effect is poor in high-water-pressure application scenarios. Contents of the invention [0003] The object of the present invention is to provide a method for welding and sealing corrugated steel pressure pipes to solve the technical problem of poor sealing effect of corrugated steel pipes in the prior art. [0004] In order to achie...
