Pipe Rolling Machine
BIT offers steel and aluminum pipe rolling machines with a large selection of pipe die sizes. We have tremendous experience and expertise in making rolling pipe benders.
A pipe rolling machine, also known as a rolling pipe bender, rolling pipe bending machine, or rolling pipe bender machine, is a mechanical device used in metalworking and fabrication to roll steel or aluminum pipes and tubes into various curves and shapes. The pipe rolling machine is a valuable tool for industries such as construction, manufacturing, and metal fabrication, where pipes and tubes need to be rolled bent, or formed to meet specific design requirements.

What people usually call a pipe rolling machine actually refers to a 3-roller pipe rolling machine. A 3-roll pipe rolling machine is an industrial device designed for bending and shaping metal pipes. It consists of three rollers, with two positioned above and one below the pipe. The pipe is passed through the rollers, and the relative movement of these rollers allows for controlled bending of the pipe.
The upper rollers are adjustable and create the desired curvature, while the lower roller provides support. The pipe is typically passed through the machine multiple times with incremental adjustments to achieve the desired bend or shape. This type of machine is commonly used in various industries such as manufacturing, shipbuilding, and construction to produce curved and shaped sections of pipes for a wide range of applications. Its simplicity and efficiency make it a popular choice for jobs requiring moderate bending precision and versatility while maintaining a straightforward operational design.
Pipe rolling machines come in various types and configurations to suit different bending and rolling requirements. Here are five common types of BIT pipe rolling machines:
PBH Pipe Rolling Machine
PBH double-pinch pipe rolling machine is a specialized type of rolling machine used for bending various types of pipes, including angle iron, flat bar, T-sections, I beams, and other structural shapes. These machines are particularly well-suited for bending metal profiles along the x-axis and y-axis to create curves, circles, rings, and various other shapes. The “double-pinch” in the name refers to the top roll having a fixed position, while the bottom two have the possibility to move and can be moved independently one from the other. This kind of machine is the most flexible and, consequently is the one that allows better performances The possibility to move independently the bottom rolls allows us to manage in the best way the pinching and bending operations, permitting them to work symmetrically and asymmetrically.
Key features of the PBH pipe rolling machine
- Two Adjustable Rolls: Unlike traditional three-roll rolling pipe benders(Pyramidal Rolling Pipe Benders) where only the top roll is adjustable, a double-pinch section rolling machine has two adjustable rolls (the bottom rolls), which allows for greater control and precision in bending profiles.
- Multi-Axis Bending: These rolling pipe bending machines are capable of bending profiles in multiple planes, enabling the creation of complex shapes and curves. This makes them suitable for applications like circular and elliptical frame components, handrails, and other structural elements.
- Hydraulic Power: PBH pipe rolling machines are powered by hydraulic systems, which provide the force needed for bending, making them well-suited for bending heavy or thick materials.
Applications of PBH pipe rolling machine
- Construction: Creating curved or circular sections for architectural and structural elements in buildings, bridges, and other construction projects.
- Manufacturing: Forming frames and components for machinery, conveyors, and material handling equipment.
- Metalworking: Bending metal profiles for various applications, such as handrails, guardrails, and staircases.
- Custom Fabrication: Crafting unique and specialized curved components for specific project requirements.
PBA Pipe Rolling Machine
PBA pipe rolling machines are equipped with CNC controls and displays, which enable precise measurements and repeatability. It is ideal for bending aluminum profiles such as rolling aluminum pipes. They are often found in manufacturing environments and metal fabrication shops that frequently work with profiles that require symmetrical bending.
Key features of the PBA pipe rolling machine
- User-Friendly Operation, Repeatability, and Accuracy: CNC control ensures that each bend is consistent and accurate. Designed to be user-friendly, and operators can learn to operate it effectively within a day.
- Handling Complex Bends: The PBA pipe rolling machine can handle complex bends, including those with tangents and multi-radius bends. This versatility is valuable in industries where intricate pipe and tube configurations are required.
- Accurate ‘Z’-Axis Control: The ability to control the twist of non-symmetrical sections is critical for applications where maintaining the shape and orientation of the section is essential.
- Variable Center Distance: The ability to adjust or vary the centers is a critical feature for the PBA pipe rolling machine because it allows for greater flexibility in the shaping process. The centers refer to the distance between the centers of the rolls, and this distance determines the final shape of the metal.
- Servo Electric System: The servo-electric system provides precise control over the bending process, offering consistency and accuracy for each bend. It ensures that the first bend of the day is the same as the last bend on the night shift.
