Flat flange is a kind of flat welding flange. The flat welding flange is mainly because the flat flange needs to be welded with the connected pipeline in the practical application. Because the flat flange is a flat surface, it is a flat welding process, so the flat flange belongs to the flat welding flange. So how is the flat flange welded? Shanxi Haokun flange Group Co., Ltd. also often needs to weld for customers. Today, let's introduce the requirements of welding flat flange and pipeline.
Before welding the flat flange to the pipeline: purchase the corresponding flat flange according to the pipeline diameter, check whether the goods meet the requirements, and prepare a set of manual electric welding equipment, a handle angle grinder, an electric air hammer and a plane ruler. Then check and debug to make sure everything you need is ready. The welding strip required for flat flange shall be heated at high temperature in advance. After preparation, assemble the flat flange and pipeline together according to the drawing, and then mark them equally and equidistantly according to the size of the flat flange, so as to make the flat flange welded symmetrically in sections. It should be noted that the welded joint should be consistent with the strength of flat flange and pipeline, with low surface roughness, flatness and no defects. Small height. After each operation of a marked position, use a caliper to measure whether the flat flange is deformed, and the current of the whole equipment should be small.Shanxi Haokun Flanges Group Co., Ltd. welds in strict accordance with the welding process. Workers are required to hammer the weld with an air hammer while welding, so as to eliminate stress.
