Aogang Machinery Co., Ltd.
Aogang Machinery Co., Ltd.
The ERW 325 Tube Mill is a large diameter ERW Tube Mill designed to produce round steel pipes with an outer diameter of 165mm–325mm and wall thicknesses of 3.0mm–14.0mm. It can also manufacture corresponding square and rectangular pipes, providing a reliable solution for large diameter welded steel pipe production.
The production line integrates uncoiling, forming, high-frequency welding, sizing, and cutting processes into a complete continuous production system. With an optimized line layout and stable operation performance, it is suitable for efficient manufacturing of large-size and thick-wall steel pipes.
The ERW 325 Tube Mill adopts advanced high-frequency welding technology to ensure stable seam quality and consistent pipe output. The optimized forming structure and automated control system help maintain precise production parameters throughout the manufacturing process.
The line supports the production of round, square, and rectangular steel tubes for various applications, including construction, structural engineering, automotive components, mechanical manufacturing, oil and gas transportation, furniture, agriculture, and chemical industries.
The control system can be customized with electrical components and motor solutions from brands such as Siemens, Yaskawa, and Allen-Bradley. This enables precise parameter adjustment, reduces manual intervention, and improves overall production efficiency.
As an experienced tube mill manufacturer, Aogang provides customized welded pipe production solutions based on customers’ capacity requirements, raw materials, and finished pipe specifications. With mature process design and technical support, we help customers achieve stable production and long-term equipment performance.
