Direct Forming Tube Mill Line 530×13

HG530 Tube Mill | High-Efficiency API & Structural Pipe Making Machine

 

Our HG530 tube mill machine is a professional industrial pipe forming equipment specially designed for mass production of high-standard API tubes and heavy-duty structural tubes. Adopting advanced direct forming technology, this premium tube mill supports flexible production of round pipes, square pipes and rectangular pipes to cover diversified pipe manufacturing demands for global pipeline, construction and engineering industries.

 

Equipped with our exclusive core roller adjustment technology, this HG530 pipe mill realizes precise adjustment of roller spacing and roller position, which perfectly satisfies customized forming standards for pipes with different specifications, wall thicknesses and shapes. The open profile forming section supports 100% full roller sharing, meaning one complete set of rollers can match all available pipe sizes. This innovative design greatly cuts down your mold replacement cost, shortens production downtime and improves overall pipe production efficiency.

 

As a reliable professional manufacturer of full-automatic tube welding lines, MaxMach provides more than just standard pipe making machines - we deliver customized one-stop tube mill production solutions for global clients. To fully comply with strict API pipe manufacturing standards and quality inspection requirements, our HG530 tube mill is integrated with a complete set of supporting auxiliary processing and testing equipment.

 

The full supporting configuration includes offline straightening machine, ultrasonic flaw detector, intermediate frequency annealing device, hydrostatic testing machine, as well as automatic pipe stacking and packaging system. All matched auxiliary devices ensure full-process quality control for finished pipes, guaranteeing all produced API tubes and structural pipes meet international industry quality certifications.

 

Model: HG530X13

 

Main parameter of the tube line:

The Pipe production line is used to manufacture weld steel round pipes, square and rectangular tubes of various sizes of Ø219- Ø530 with 4-13 mm of wall thickness (round pipe), 170×170 до 400×400 mm with 4-13 mm of wall thickness (square pipe) and 260×130 до 400×200 mm with 4-13 mm of wall thickness (rectangular pipe) made of rolled steel strip, welded with a straight seam using high-frequency induction welding.

The principle of operation is based on welding the edges of the seam of the pipe billet, when heated in a magnetic field, followed by compression of the edges in automatic mode with continuous movement of the pipe billet along the line.

Working Flow:

 

Coil loading → uncoiling → shovel head → pinching&leveling → Automatic shearing and butt-welding→ accumulating → Centering → Trimming → Scrap crushing →Strip ultrasonic flaw detection → Guiding (including 5 roll leveling) → Feeding → forming → HF welding → deburring (outside an inner ) → Weld seam grinding → ultrasonic flaw detection → intermediate frequency annealing → air cooling →water cooling → sizing and straightening → cut to length → run out table → round pipe straightening → end facing → hydro testing → manual checking and repairing → tube weighing, measuring, printing, marking → automatic stacking and packing (including weighting and tube package marking) → storage
