Steel elbow machine is used for making butt
weld elbow such as , Carbon Steel Elbow , alloy steel elbow , stainless steel elbow . there are two model : hot forming elbow
machine and Cold Forming Elbow Machine .
Advantage of the steel elbow machine :
1. Machine
production speed is very fast.
2. Save the
raw material.
3. Less
process and easy to operate
