Bend pipe processing technology greatly benefits our daily lives, but issues may arise during product use, such as micro-cracks appearing in the bend pipes. If the deformation temperature during production exceeds a certain level, the product will deform.
During bending tube processing, microcracks may appear on the outer surface. This situation typically occurs in two main cases, which may be related to the material of the bent steel tube. Under similar forming conditions with certain low deformation speed and high tensile strength, any bending operation performed by the equipment in such circumstances could potentially cause damage.
Each elbow pipe is formed through multiple bending processes during manufacturing. During production, the steel pipe can be effectively placed on the bending machine, where the equipment applies a bending moment to the pipe, resulting in an appropriate deformation of the pipe layout.
The bending tube moves upwards by the pivot point of the front lower mold main cylinder, causing the steel pipe to deform and bend along the curve of the upper mold until it is shaped. During the processing, the deformation of the steel pipe mainly occurs in the upper mold, which acts as a mold base.
