Working Principle of Φ8-30 mm steel pipe making machine

Hydraulic cylinder of strip feeding unit holds down steel strip. The feeding motor drives the feeding roll to fill strip into the accumulator by friction force. The main motor rotates supply roll of the accumulator cage to store steel strip in the inner and outer storage zone. The drive motor will stop after one coil finished, and will resume feeding after cutting and welding of another coil.

Manufacturing process

Manufacturing process of steel pipe making machine is made up of uncoiling, molding, welding, polishing, sizing, straightening and cutting, etc. Rolling speed can be adjusted correspondingly within proper range of pipe diameter and wall thickness.
