Stainless Steel Tube Bending

Detroit Tube Products has delivered trusted stainless steel tube bending services across Michigan and the Midwest since 1911. Whether you need custom exhaust systems, precision aerospace components, medical tubing, or high-pressure industrial parts, we have the tools and expertise to deliver.

With bending capacities ranging from 3/4″ to 6″ outside diameter (OD) and a massive in-house die inventory, we provide faster turnarounds and lower costs for your specific project needs.

Why Choose Stainless Steel?

Stainless steel stands out for its superior corrosion resistance, clean aesthetic, reflective finish, and remarkable durability under intense pressure. It maintains its structural integrity and appearance in harsh environments where standard carbon steel often fails.

We bend both welded and seamless stainless steel tubing, accommodating round, square, and rectangular shapes. To achieve a successful bend, we carefully calculate several critical factors:

• Outside Diameter (OD)
• Centerline Radius (CLR)
• Wall Thickness
• Bend Angle
• Tube Elongation

Note: For welded stainless tubes, weld quality plays a vital role in preventing cracking or deformation during the bending process.

The Golden Standard: Mandrel Bending

Mandrel bending is the preferred method when you need smooth, wrinkle-free, full-flow curves. This process protects the strength of the tube and maintains the internal diameter, making it essential for:

• Tight-radius bends (such as 1D or severe radius bends)
• Thin-wall tubing
• Harder materials like 316 stainless steel

Mandrel Types We Use

• Plug Mandrel: Best suited for heavier wall thicknesses.
• Standard Open Pitch Mandrel: Our most commonly used tooling for general applications.
• Thin Wall (Closed Pitch) Mandrel: The ideal choice for thin-wall stainless steel.

Alternative Bending Processes

Beyond mandrel bending, we offer a variety of specific processes tailored to the unique demands of your project:

• Rotary Draw Bending: Highly precise and versatile, perfect for complex parts.
• Compression (Crush) Bending: A highly cost-effective method for simpler bends.
• Ram Bending: A traditional technique commonly used in automotive work.
• Roll Bending: The best option for large-radius curves or construction projects.

Our Capabilities and Materials

We offer severe radius capabilities as a standard across all sizes, and we can achieve the close tolerances your designs require. Because we carry a vast selection of in-house dies, you avoid tooling charges on most common sizes. We also provide full assembly services, including bosses, bracketry, flanges, brazing, and weldments.

Materials We Bend Daily

• 304 Stainless: Excellent general-purpose corrosion resistance.
• 316 Stainless: Superior durability for harsh environments and marine applications.
• 301, 301L, 301LN: Available upon request, along with other specialized grades.

Industries We Serve

• Automotive and custom exhaust (performance vehicles, hot rods, motorcycles)
• Aerospace and aviation
• Medical equipment
• Construction and architecture
• Food service equipment
• Marine and boating
• Various low-to-medium volume industrial applications

Why Partner with Detroit Tube Products?

The stainless steel tube bending process has evolved significantly over the years with advancements in technology. However, the core elements remain consistent: the tube metal alloy, the machine, the tooling, and the lubrication. Understanding these fundamentals is key to achieving precise and efficient bends.
