Φ165 HIGH-FREQUENCY WELDED PIPE MILL LINE
1 General Introduction
Ф165 high-frequency welded pipe production line is designed to produce welded pipes of 60~140mm in diameter and 1.5~6.0mm in wall thickness as well as square and rectangular pipes and formed sections of the corresponding size. The products conform to BS/ASTM Standard. Adopting the advantages of the equipment of the same kind at home and abroad, each element of the production line is designed with new ideas. The application of PLC automatic control system and British Eurotherm digital speed regulating unit guarantee that the production line works reliably and operates and maintains easily.
