ELBOW's processing technology has brought great help to our daily life, but there are many problems in the process of using the product, such as microcracks in the elbow, and the product will deform if the deformation temperature exceeds a certain level during the manufacturing process.
When ELBOW is processed, there are two main cases of microcracks on its outside, which may be related to the material of the bent steel pipe.
Under the similar forming conditions of low deformation speed and high tensile resistance of the product, all bending construction of the equipment may be damaged under such conditions.
