Features:

The machine is one of main machines for LSAW mill, which serves to mechanically expand LSAW pipes step by step with expanding head in order to ensure accurate roundness, straightness and dimensional accuracy of the pipes in accordance with the technical requirements, and relief the residual stresses.

 

The machine consists of power cylinder, horn drawbar, expander-head, horn support and carrying pipe carriage. The expanding head consists of a multi-faced wedge, addressed as cone, drawn by means of a draw bar into a set of circumferentially arranged expander jaws.

 

They are forced against the inside wall of the pipe which expands it to size and straighten it along the entire length. This method assures that the pipe is forced outwardly in a uniform fashion regardless of any differences present in the pipe material. The expansion ratio is 1~1.5% of diameter.
