10-38mm High Frequency Pipe Making Machine , Welded Pipe Production Line

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.
