Flange welding precautions

　　Butt-welding flanges have a long service life so insulation flanges, low pressure flanges, insulation flange manufacturers should pay more attention to the details of the planning program to break.

　　In the use of butt-welding flange need to pay attention to several places, butt-welding flange use points of attention:Calculation and material can be very good progress in the use of raw materials, to complete the butt-welding flange blanks one of the important aspects of the refinement. Too much raw material not only forms the blank waste, and will also aggravate the mold cavity wear and energy loss.

　　Butt weld flange manufacturers In addition, the production quality of the undercut end face has a great influence on the process and the quality of die forging. The ultimate goal of heating is to reduce the deformation force of mold casting and improve the plasticity of steel products. However, butt-welding flange heating also brings a series of production problems, such as overheating, oxidation, decarburization and overcooking. The control of the beginning and end of the mold forging temperature has a great influence on the arrangement and function of the butt-welding flange.

　　Flame furnace heating has the advantages of low production interest and wide applicability, but the heating time is long, oxidization and decarburization are easy to occur, and the production conditions need to be improved continuously. Induction heating furnace with fast heating, less oxidation characteristics, but poor adaptability to the blank shape scale and material changes. Die forging forming is the external force so, the correct accounting deformation force, selection of welding flange production equipment, forging mold calibration basis.

　　Butt-welding flanges have a long service life, so insulation flanges, low-pressure flanges, insulation flange manufacturers should pay more attention to the details of the breakthrough in the planning program, the use of the product's marvelous planning to make its function is constantly improved. Insulation flange, low pressure flange, insulation flange manufacturer is a general term for pipeline flange joints that have both the sealing function required for buried steel pipelines and the electrical insulation function required for electrical corrosion protection works.
