Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a water conservancy project pressure steel pipe docking device. Background Art

[0002] Penstock is a steel pipe used to transport water at extremely high pressure. It is widely used in many fields such as hydropower, oil and gas, chemical industry, water supply and drainage, electricity, military and aerospace. Its manufacturing process is rigorous, including raw material processing, steel plate bending and welding, forming heat treatment, surface treatment and testing to ensure the quality and performance of the steel pipe. The performance parameters of penstock, such as tensile strength and yield strength, are key indicators to measure its performance and safety. Especially in the field of hydropower generation, penstock, as the "aorta" of the hydropower station, needs to withstand the impact of huge water flow, so it needs to be welded from extra thick steel plates to ensure its strength and durability.

[0003] When installing the pressure steel pipe, the two need to be butt-jointed so that the joint fits tightly and the two are always kept on the same axis to facilitate welding and connection after butt-jointing. In addition, due to the transportation and storage of the pressure steel pipe, the dust and rust remaining on its end face will affect the connectivity of the welding, and manual cleaning is too cumbersome and time-consuming. In order to solve the above problems, while facilitating the adjustment of the axis of the pressure steel pipe for butt-jointing, the end face position can also be polished and cleaned before connection, so as to facilitate its use during connection processing. For this reason, we propose a butt-jointing device for pressure steel pipes in water conservancy projects. Utility Model Content
