High Frequency Welding Tube Mill Machine Straight Seam Roll Pass Design

Straight Seam High-Frequency Welded Pipe Production Line Roll Pass Design

ZHG38 High-Frequency Welded Pipe Production Line is designed to produce welded pipes of Ф10-Ф38mm in diameter and 1.0-2.3mm in wall thickness and square pipe 8x8-30x30mm,thickness 1.0-2.0mm. Adopting roll pass design, the production line can manufacture welded steel pipes with good quality machining and high precision assembling.

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,ZHG38 production line adopts the double-radius hole style of design .
