The invention provides a butt joint device for pipe connectors. The butt joint device is characterized in that the butt joint device comprises a left positioning shaft and a right positioning shaft; and the two sections of pipe connectors to be connected in a butt joint manner can be arranged on the left positioning shaft and the right positioning shaft respectively. By means of the butt joint device for the pipe connectors, groove positioning can be conducted on the pipe connectors before the butt welding operation is conducted on the special steel pipe connectors in a boiler, and the postwelding straightness of the pipe connectors can be effectively ensured. In addition, the butt joint device is simple in design structure, low in manufacturing cost and easy and convenient to assemble, disassemble and operate, and can be conveniently put into use on a large scale in production workshops. For pipe orifice inner diameters of different calibers, a left / right bushing ring of a corresponding size can be selected to be assembled. Therefore the butt joint device has quite high practicability and can be conveniently put into use on a large scale in production workshops.
Description
technical field [0001] The invention relates to a pipe joint butt joint device. Background technique [0002] At present, the short pipe joints in the boiler are designed as dissimilar steel butt welding structures, and there is no positioning device between the short pipes during the groove butt welding process. After the pipe joint is welded, there are obvious kinks (the straightness is seriously out of tolerance), and the subsequent turning process of the inner wall of the pipe needs to be carried out, which consumes manpower and material resources and is not conducive to workshop production. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pipe joint butt joint device that can effectively ensure the straightness of the pipe joint after welding. [0004] In order to solve the above technical problems, the present invention provides a pipe joint docking device, which is characterized in that it includes a lef...
