Hot Forming Seamless Elbow Machine

Here’s a fast, informative look at how a hot forming seamless elbow machine works. In this video, we walk through the complete manufacturing process—from material preparation to final elbow production—showing how axial pushing, medium-frequency heating, and a bull-horn mandrel combine to expand and bend pipes in a single operation. You’ll see the machine in action, learn the core principles of metal flow and wall thickness compensation, and understand the key steps for producing 90° long-radius seamless elbows in carbon steel, alloy steel, and stainless steel.
