The reasons for the fracture of the forged flange can be as follows: 1. Material reasons: the material used in the flange may have quality problems, such as containing too much impurities or material hardness is not up to standard, which will lead to the fracture of the flange. 2. Design reasons: If the design of the flange is unreasonable, such as uneven wall thickness, too large or too small size, improper connection mode, etc., it will make the flange unable to withstand normal loading when used, resulting in fracture. 3. Manufacturing process reasons: there may be factors such as unreasonable processes or operational errors in the manufacturing process, such as improper temperature control, uneven pressure, excessive cooling speed, etc., which may lead to defects inside the flange and eventually lead to fracture. 4. Stress concentration: In the process of use, the flange may withstand a variety of static and dynamic loads, long-term stress action may lead to stress concentration, especially in the joint surface and holes and other parts, easy to produce stress concentration, and eventually lead to fracture. 5 Environmental factors: Environmental factors are also an important factor leading to the fracture of the flange, such as corrosion, wear, high temperature and other harsh environment will accelerate the aging and fatigue of the flange, resulting in fracture. To solve the fracture problem of the flange, it is necessary to comprehensively consider and optimize the material selection, design, manufacturing process, stress distribution, etc., to ensure that the flange has a high strength and reliability. At the same time, in the normal use process, it is necessary to regularly check and maintain the performance of the flange, to avoid use in harsh environments or more than the load of the flange.
