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 researching mandrel bending companies, you might ask yourself what does ISO certification mean? To be ISO compliant, a company must follow the rules of the International Organization for Standardization. Also, an ISO certification proves that the company is following international standards. In the case of Detroit Tube Products, they are ISO certified with the American Systems Registrar, LLC, or ASR.

Detroit Tube Products ISO certification is ISO 9001:2015. This means Detroit Tube Products follows all International Quality System Standards. Also, when looking for any type of tube bending company, you should always make sure they are an ISO Certified Manufacturer.

Tube Forming and Shaping

When it comes to tube end forming, we can offer reduction tube end forming, beaded, flare, or expansion.  The reduction is just how it sounds. We reduce the diameter using dies and tapered rings.  The beaded forming is adding beads at the end to improve the tube to hold a hose.  Also, the expansion end is enlarging the end of the tube so tubes can fit inside.

Our products are used in a variety of industries such as diesel engines, mining equipment, food service equipment, radiators, fire suppression, car wash systems, and many more! Along with forming, we also offer tube bending services, and we can build assemblies. Our tube forming and shaping have been used in a multitude of projects. From custom car exhausts to complex engines, our quality finished products can help you.

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.
