Precautions for flange welding

The service life of butt welded flanges is long, so the planning schemes of insulation flanges, low-voltage flanges, and insulation flange manufacturers should pay more attention to breaking down details.

When using butt welded flanges, there are several points to pay attention to. The key points to note when using butt welded flanges are: material calculation and cutting, which can greatly improve the utilization rate of raw materials and are an important step in refining the blank of the butt welded flange. Excessive raw materials not only result in rough material waste, but also exacerbate mold cavity wear and energy loss.

In addition, the production quality of the cutting end face has a significant impact on the process and forging quality of the welded flange manufacturer. The ultimate goal of heating is to reduce the deformation force of mold casting and improve the plasticity of steel products. However, heating the welding flange also brings a series of production problems, such as overheating, oxidation, decarburization, and overburning. Controlling the initial and final forging temperatures has a significant impact on the arrangement and functionality of butt welded flanges.

Flame furnace heating has the advantages of low production interest and wide applicability, but the heating time is long and oxidation and decarburization are prone to occur, and the production conditions also need to be continuously improved. The electric induction heating furnace has the characteristics of fast heating and less oxidation, but its adaptability to changes in the shape, scale, and data of the blank is poor. Die forging is a process that occurs under external forces. Therefore, the correct calculation of deformation force is the basis for selecting welding flange production equipment and conducting forging die verification.

The service life of butt welded flanges is long, so the planning schemes of insulation flanges, low-voltage flanges, and insulation flange manufacturers should pay more attention to breaking down details and continuously improving their functions through the wonderful planning of products. Insulated flanges, low-voltage flanges, and insulated flange manufacturers are the 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 engineering.
