  Precautions for use of flange products:

  1. In order to prevent eye to eye corrosion caused by flange heating, the welding current should not be too large, less than 20% of carbon steel electrode, the arc should not be too long, the interlayer should be cooled quickly, and the narrow weld bead is appropriate.

  2. The welding rod shall be kept dry when it is used. The titanium calcium type shall be kept dry at 150 ℃ for 1 hour, and the low-a hydrogen type shall be kept dry at 200-250 ℃ for 1 hour to prevent the coating of the welding rod from sticking oil and other dirt, so as to avoid the increase of carbon content in the weld and the impact on the quality of the weldment.

  3. During the welding of flange pipe fittings, carbides are precipitated due to repeated heating, which reduces the corrosion resistance and mechanical properties of products.

  Main functions of Forged Stainless Steel Welding Socket Flange:

  1. Connect the pipeline and keep the sealing performance of the pipeline;

  2. It is convenient for the replacement of a certain section of pipeline;

  3. Easy to disassemble and check the pipeline condition;

  4. It is convenient to close a section of pipeline
