Abstract

The invention discloses a welding assembly tool for the pressure-bearing pipeline of a hydrogen production device. The welding assembly tool comprises an assembly piece, a steel pipe and a positioning assembly used for assisting welding of the assembly piece and the steel pipe, and the assembly piece is a tee joint or a four-way joint or a flange or a concentric reducing pipe; and the positioning assembly comprises a main rod, a threaded sleeve and a movable sleeve. The welding assembly tool is ingenious in design and good in effect.

Description

technical field [0001] The invention relates to the technical field of hydrogen production, in particular to a welding assembly tool for a pressure-bearing pipeline of a hydrogen production device. Background technique [0002] The pressure-bearing pipeline of the hydrogen production device is mainly composed of flanges, tees, crosses, concentric reducers and other pipe fittings and steel pipes. The quality requirements for the pressure-bearing pipelines of the hydrogen production unit are extremely high, and it is necessary to control the amount of misalignment, concentricity and end deflection generated during the welding process. [0003] It is difficult for conventional welding assembly tools to maintain the alignment between the assembly openings of flanges, tees, crosses, concentric reducers, etc. There is an offset between the workpiece and the steel pipe, resulting in excessive misalignment, concentricity and end deflection exceeding the standard requirements, resul...
