The processing process of forged flange may encounter the following common problems: Internal defects: In the forging process, due to the non-uniformity of the metal material or improper operation, it may lead to internal defects, such as pores, slag inclusion, etc. These internal defects may affect the strength and sealing performance of the flange. Dimensional error: The dimensional accuracy of forged flanges is high, but there may be dimensional errors in the processing process, such as deviations in length, width, aperture and so on. This may lead to difficulties in the installation and connection of flanges, affecting the normal operation of the entire pipeline system. Surface quality issues: The surface quality of forged flanges is critical to sealing performance. However, due to the particularity of the forging process, there may be problems such as substandard surface roughness, burns, cracks, etc., which will have a negative impact on the sealing effect of the flange. Material selection and heat treatment: The choice and heat treatment of forged flange materials have an important impact on the quality and performance of the final product. If the selected material is not suitable or the heat treatment process is not correct, it may lead to the strength, hardness, corrosion resistance and other aspects of the flange do not meet the requirements. Welding problems: Some forged flanges need to be welded, such as welded neck flanges. During the welding process, problems such as welding defects and welding deformation may occur, which will affect the structural integrity and sealing performance of the flange. In response to these common problems, processing manufacturers usually take strict quality control measures, including material inspection, reasonable process parameter setting, advanced equipment and technology, rigorous process operation, etc., to ensure that the quality of forged flanges meets the relevant standards and specifications.
