Pipe end-forming machines

TTEngineering offers a versatile range of pipe end-forming machines engineered to shape and deform metal pipe ends with wall thicknesses ranging from 0.3 mm to 2.0 mm. These systems are ideal for applications in the air-conditioning, automotive, and chimney sectors, where precise end finishing and reliable joint quality are essential for consistent system performance.

The machines support various end-forming operations such as expanding, reducing, flaring, beading, and closing, depending on the application. They can be supplied as stand-alone units or integrated into complex automated production lines, and each system is fully customizable to meet specific technical and production requirements.

BCF

The BCF is a pipe end-forming machine designed for precision expansion using an 8-segment internal expander in combination with a 2-segment external matrix. This dual-action system ensures uniform material deformation and excellent dimensional repeatability, ideal for applications requiring reliable and tight-fitting joints.

The machine is available in either horizontal or vertical configuration and can be equipped with hydraulic or electric actuation, depending on process requirements. Tooling change is required when switching diameters, allowing for tailored performance across different pipe formats.

The BCF is ideally suited for HVAC, chimney, and industrial piping applications, offering a robust solution for manufacturers seeking repeatable, high-quality end expansion with configurable system architecture.

BRU – combined expansion and beading machine

The BRU is a combined pipe end-forming machine that performs both expansion and beading in a single cycle. It features an 8-segment expansion head for internal deformation and an external roll system to form female ends, while male ends are shaped using two motorized forming rolls.

A key advantage of the BRU system is that no roll change is required when switching diameters, ensuring fast setup, minimal downtime, and efficient diameter transitions across production batches.

This configuration delivers tight dimensional tolerances, clean bead geometry, and consistent mechanical sealing quality, making it ideal for HVAC ducts, chimney connectors, and ventilation systems where secure and form-locked joints are essential.

BST – shrinking and reduction machine

The BST is a high-force shrinking and reduction machine equipped with 8 internal and 8 external forming sectors, specifically designed to process thicker pipes and smaller diameters with high precision and repeatability.

TTEngineering has developed this machine with optimized motion systems that ensure a controlled forming cycle, effectively eliminating surface marks or deformation traces on the finished parts. This makes the BST particularly suitable for applications where aesthetic quality and mechanical integrity must be preserved simultaneously.

Its robust configuration is ideal for forming gasket seats and tight mechanical joints, offering uniform material reduction without compromising structural performance.

BRD – dual-process roll-forming machine

The BRD is a roll-forming machine designed for high-precision end shaping operations. It features two external motorized rollers and one internal roller, enabling efficient and uniform material deformation. A key advantage of the BRD is its ability to perform two distinct forming processes without requiring a tooling or format change, significantly reducing downtime and setup complexity. The machine is available in either horizontal or vertical configuration, allowing flexible integration into a variety of production layouts. Compact, versatile, and efficient, the BRD is an excellent choice for manufacturers requiring repeatable forming quality, process flexibility, and streamlined production flow in HVAC, chimney, and metal ducting applications.

BBE – reverse flanging machine

The BBE is a reverse flanging machine specifically designed to create cut-resistant pipe ends, improving both safety and handling quality in finished components. The system features a single external roller and an internal mandrel, which must be replaced according to the pipe diameter to ensure precise and consistent forming results. Compact and easy to operate, the BBE is ideal for applications in the HVAC, ventilation, and chimney sectors where safe, smooth pipe edges are essential for operator protection, ease of assembly, and seal integrity.

BFL – dual-head flanging machine

The BFL is a high-performance flanging machine equipped with two independently driven heads, allowing the formation of precise 90° flanges on both ends of the pipe in a single cycle. Thanks to its advanced design, the BFL can produce flanges of different lengths without requiring tool changes when switching pipe diameters, ensuring outstanding flexibility and efficiency across production batches.

TTEngineering has developed a dedicated working cycle that ensures the creation of perfectly square 90° flange angles and flat, uniform flange surfaces, guaranteeing both mechanical accuracy and aesthetic quality in the finished product.

Available in both horizontal and vertical configurations, the BFL is ideal for medium- to high-volume manufacturing of HVAC, ventilation, and industrial ductwork components, where flanging precision, repeatability, and minimal setup time are key production priorities.

IRB – multi-station roll-forming machine for automatic lines

The IRB is a multi-station, multi-process roll-forming machine designed for integration into fully automated production lines. Engineered to perform sequential operations such as reverse flanging, expansion, and final roll forming, it enables streamlined pipe-end processing within a single compact system. The system can be equipped with marking or labelling devices to support traceability and identification, and is available in both horizontal and vertical configurations to suit different plant layouts and production flows.

TTEngineering has developed a complete set of automation solutions around the IRB platform, including the design of custom tooling, enabling the accurate reproduction of all required end-forming geometries specified by pipe manufacturers. These include precision male-female conical connections designed for seal-tight joints without gaskets, supporting both performance and assembly efficiency.

With this comprehensive range of pipe end-forming machines, TTEngineering enables manufacturers to achieve precise, high-quality pipe ends tailored to a wide variety of applications. Each model combines robust construction with process flexibility, supporting efficient production and ensuring superior product performance across demanding sectors such as HVAC, ventilation, and chimney systems.
