Tube Bending

  • 3/4″ to 6″ diameter tube bending capacity
  • Severe radius capability standard – all sizes
  • Close tolerance available

Large Inventory of Tubing Stock For Tube Bending

Materials Used: All metals for low-pressure applications.

Machines/Processes Used: Mandrel bending and roll-form bending. Bend “1D” (tight radius). Also, dual tube bending (tube within a tube while maintaining flow).

Minimums/Maximums: Single-piece to moderate production (1000/month)

Sizes: 6″ outside diameter 11 gage tube or 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.

Stainless Steel Tubes: 316 stainless, 304 stainless is most common. 400 series not stocked,  but can be ordered with tube bending service

ISO Certified

When researching mandrel bending companies, you might ask yourself, what exactly does ISO certification mean? To be ISO compliant, a company must follow the rules of an 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 on a hose.  Also, the expansion end is enlarging the end of the tube so other 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 an additional layer of material over an already existing part, due to the powerful mechanical bond between the flanged tube and over-molded object.
