A High Frequency Welding Tube Mill, also known as a high frequency welded pipe mill, is a complete production line used for the continuous manufacturing of welded steel pipes.
The equipment uses steel strips (coils) as raw material and produces round pipes, square pipes, rectangular pipes, or special-shaped welded tubes through processes such as forming, welding, sizing, and cutting.
High frequency welding tube mill technology is widely applied in the production of ERW pipes (Electric Resistance Welded Pipes) and is recognized as one of the most mature and efficient welded pipe manufacturing processes in the steel pipe industry.

The core of a high frequency welding tube mill lines in high frequency induction heating and resistance welding technology. The basic working process includes the following steps:
The steel coil is uncoiled and preliminarily leveled to provide stable raw material for the subsequent forming process.
The steel strip is gradually bent by multiple forming rolls, transforming from a flat strip into an open-round tube or profile.
High frequency current is concentrated on the strip edges through induction or contact welding
The strip edges are rapidly heated to the welding temperature
Under the action of squeeze rolls, the two heated edges are fused together to form a solid weld seam
After welding, excess internal and external burrs are removed to improve the surface quality and inner wall finish of the pipe.
Sizing stands are used to ensure pipe dimensional accuracy and straightness.
The pipe is automatically cut to preset lengths to obtain finished welded steel pipes.
