Precision Tube Bending Services

CNC (Computer Numerical Control) tube bending uses programmable software to control multiple axes, allowing for complex, repeatable bends with tight tolerances. NC (Numerical Control) bending is more manual and typically suited for simpler geometries and shorter runs. In short: CNC bending is best for high precision, complex parts, and repeatability. NC bending works well for simpler bends with lower setup complexity. Most modern production, especially for multi-bend or tight-tolerance parts, relies on CNC bending.

A 1D bend means the centerline radius (CLR) of the bend is equal to the tube's outside diameter (OD). For example, a 2" OD tube with a 2" centerline radius is a 1D bend. These are considered tight-radius bends and require proper tooling and process control to avoid deformation, wrinkling, or flattening.

Centerline radius (CLR) refers to the distance from the center of the bend to the centerline of the tube. It's one of the most important specifications in tube bending because it directly affects bend feasibility, tooling requirements, and material behavior during forming. CLR is typically expressed relative to tube diameter (e.g., 1D, 2D, 3D).

Tube bending can be performed on a wide range of materials, including carbon steel, stainless steel, aluminum, and alloy steels. Material type, wall thickness, and hardness all influence how tight a bend can be achieved and what tooling is required.

Tube bending capabilities vary depending on equipment and tooling. At H-P, we support tube bending from 3/8" up to 10" OD, covering everything from small precision components to large-diameter industrial applications.

A compound bend is a tube with bends in multiple planes, rather than all bends occurring on a single axis. These are commonly used in applications where space constraints or routing complexity require more advanced geometries. Compound bends require precise programming and control to maintain accuracy across multiple bend orientations.

The key difference comes down to how size is measured. Tube is specified by outside diameter (OD) and wall thickness, while pipe is specified by nominal pipe size (NPS) and schedule. Tube bending is typically used for applications requiring tighter tolerances and more precise geometry, while pipe bending is often used in fluid transport systems.

Yes, depending on the project, we can work with customer-supplied material. This is typically evaluated based on material consistency, condition and handling, and compatibility with the bending process. If you're considering supplying material, it's best to review specs with our team upfront to ensure a smooth process.
