High Frequency Welded Pipe Mill for 21-63mm Round Pipes

The ERW tube mill & pipe mill is a series of machines that builds longitudinal weld seam tubes and pipes with steel strips of certain width. The process includes:

• Uncoiling and flattening steel coils into strips
• Forming strips into round pipe shape via rolling machine
• Welding with high frequency solid state welder
• Sizing to expected dimensions
• Cutting to length and bundling finished pipes

This equipment produces pipes for:

• Petroleum and natural gas pipelines
• City gas distribution networks
• Chemical processing plants
• Power generation facilities
• Structural steel trusses
• Water and gas pressure pipelines
