Overview of Expanding Mill Machine For JCOE LSAW Pipe Mill Production Line

The Expanding Mill Machine For JCOE LSAW Pipe Mill Production Line is final dimensional calibration equipment installed on the JCOE LSAW pipe production line after welding procedures. This Expanding Mill Machine For JCOE LSAW Pipe Mill Production Line adopts a hydraulic mechanical expanding structure to conduct full-length cold expanding treatment on welded steel pipes. Multi-segment expanding dies on this Expanding Mill Machine For JCOE LSAW Pipe Mill Production Line expand pipe inner diameter uniformly from inside out to eliminate residual stress generated during forming and welding, revising out-of-roundness and dimensional fluctuation of the pipe body. Matched with front and rear roller conveying frames, the unit realizes continuous pipe feeding and automatic expanding. All expanding pressure and stroke data on this Expanding Mill Machine For JCOE LSAW Pipe Mill Production Line are set via a numerical control system and stored for various pipe specifications. After expanding, finished pipes reach unified inner diameter tolerance to satisfy inspection and subsequent anti-corrosion processing standards of LSAW pipe.
