Description
Technical Field
The invention relates to the technical field of flange processing, in particular to petroleum pipeline connecting flange processing equipment and processing technology thereof.
Background
At present, oil transportation mainly depends on pipeline transportation, and because oil transportation distance is long and a tortuous path is required to be passed, a plurality of sections of pipelines need to be connected. The current common pipeline connection mode is to manually weld the flange plate on the pipeline mouth and then connect two sections of pipelines by using bolts to connect the flange plate. In the process of welding the pipeline and the flange plate, weld flash can be generated, so that the joint of the pipeline and the flange plate needs to be polished, the joint is smooth, gaps can not be generated during overlaying welding, and welding is firmer. By the aid of the method, firmness and tightness of pipeline connection can be guaranteed, and accordingly safety and high efficiency of petroleum transportation are guaranteed. At present, the following problems exist when welding a flange plate and a petroleum pipeline:
Before the welding of the flange plate and the pipeline, the flange plate and the pipeline are required to be aligned, and the interface is ensured to be flush so as to be convenient for welding. However, at present, manual work is often adopted for the flange plate, and the flange plate and the pipeline cannot be completely attached or offset due to lower precision of the manual work. This results in misalignment of the flange with the pipe orifice after manual welding, thereby creating a gap at the joint. These gaps are corroded or worn by petroleum in long-term use, eventually resulting in petroleum leakage, severely affecting the service life, and thus improvements are needed.
