Tube Bending

At Detroit Tube Products, we specialize in precision tube bending and forming services, offering unmatched expertise and capabilities for a wide range of industries. From heat exchangers to custom exhaust systems, our solutions are designed to meet the most demanding requirements. Here’s an overview of our capabilities and services:

Tube Bending Capabilities

Diameter Range: 3/4″ to 6″ tube bending capacity

Severe Radius Bending: Standard for all sizes, including tight-radius bends (1D)

Close Tolerance Bending: Ensures precision for even the most complex projects

Material Versatility: We bend all tubing materials and shapes, specializing in stainless steel

Large Die Inventory: Extensive tooling options to accommodate diverse needs

Stock Inventory: Large inventory of tubing materials for quick turnaround

Material and Processes

Materials Used

All metals for low-pressure applications, including

  • Stainless Steel: 316 and 304 stainless are the most common steel used. 400 series available upon request.
  • Other Metals: Suitable for various low-pressure applications.

Processes

  • Mandrel Bending: Ideal for tight-radius bends and maintaining flow in tubes.
  • Roll-Form Bending: For larger radius bends.
  • Dual Tube Bending: Tube-within-a-tube bending while maintaining flow.

Specifications and Applications

Minimums/Maximums: From single-piece prototypes to moderate production runs (up to 1,000 pieces per month)

Sizes Capabilities 

  • Up to 6″ outside diameter, 11-gauge tube.
  • 4″ schedule 160 pipe.

Possible Applications: All low-pressure applications where casting is too heavy or costly. In addition, product development, mass-customization in engine upfits, specialty vehicles, marine and yacht, engine exhaust, generators, architectural or interior design, display projects, and cleaning equipment from car washes to commercial dishwashers.

ISO Certified

When evaluating mandrel bending companies, you might wonder, What does ISO certification really mean? ISO certification signifies that a company adheres to the rigorous standards set by the International Organization for Standardization. It’s a mark of quality and consistency, proving that the company meets internationally recognized benchmarks.

At Detroit Tube Products, ISO certification is a point of pride. Certified by the American Systems Registrar, LLC (ASR), Detroit Tube Products holds an ISO 9001:2015 certification. This certification ensures compliance with all International Quality System Standards, reflecting their commitment to delivering high-quality, reliable tube bending services.

When choosing a tube bending company, always prioritize those with ISO certification. It’s your assurance that the company operates with precision, quality, and accountability.

Tube Forming and Shaping

When it comes to tube end forming, we offer a range of options, including reduction, beaded, flare, and expansion end forming. Each process is tailored to meet specific needs:

  • Reduction: Decreasing the tube’s diameter using precision dies and tapered rings.
  • Beaded Forming: Adding beads to the tube end to securely hold hoses in place.
  • Expansion: Enlarging the tube end to allow for seamless fitting with other tubes.

Our products serve a wide variety of industries, including diesel engines, mining equipment, food service equipment, radiators, fire suppression systems, car wash systems, and more. Beyond forming, we also specialize in tube bending and assembly building, offering comprehensive solutions for your projects.

From custom car exhausts to intricate engine components, our expertly crafted tube forming and shaping services deliver the quality and precision you need to bring your vision to life.

Flaring and Flanging

Tube flaring is a type of forming operation, known usually as work hardening. which is the strengthening of a metal or polymer by plastic deformation. Also, the strengthening occurs by dislocation movements and generation within the material’s crystal structure. In addition, a flare nut is then used to secure the flared tube’s tapered end to the fitting, producing a strong seal.

Flanging heat causes the tubing wall to curve outward at a 90-degree angle from the machine’s direction. In addition, tube flanging is often used for applications with over-molding, the process of adding additional layers of material over an already existing part, due to the powerful mechanical bond between the flanged tube and over-molded object.
