brief introduction
The big and small heads whose center is in a straight line are
called concentric big and small heads. The commonly used forming
process is reduced diameter pressing, expanded diameter pressing or
reduced diameter plus expanded diameter pressing. Stamping can also
be used for reducing pipes of some specifications.
distribution characteristics
(1) The bending moment caused by the area pressure difference between the large and small ends of concentric reducer under the action of internal pressure causes the relative opening of the large end and the relative contraction of the small end;
(2) Under the action of internal pressure, the circumferential stress on the inner surface of the large end on the eccentric side and the outer surface of the middle part on the eccentric side of the eccentric reducer is the largest.
