1. Description of goods:
MA-32 HF Welded Pipe Making Machine with high frequency tube mill
gear box drive and cold saw
2. Introduction:
The MA-32 high-frequency welded pipe production line is used to
produce both welded pipes of 10～38mm in diameter and 0.5～2.5mm in
wall thickness. Square and rectangular pipes and deformed pipes of
the corresponding size are available too. This equipment uses roll
pass design, so the production line can produce welded steel pipes
which has the feature of good quality machining and precision
assembling.
