Brief introduction of ERW high precision tube rolling mill

HG114 High-Frequency Welded Pipe Mill Line is designed to produce welded pipes of 50～101.6mm in diameter and 1.0～4.0mm in wall thickness as well as square and rectangular pipes and deformed pipes of the corresponding size. Adopting roll pass design, the production line can manufacture welded steel pipes with good quality machining and high precision assembling.

Ⅰ、According to the designing guideline of improving the operating character & environment and the safety & producing character, reducing the cost of the roller to guarantee high efficiency, HG114 production line adopts the double-radius hole style of design.
