McKiney Manufacturing Custom Tube Bending

We are proud to offer custom mandrel CNC pipe bending and tube bending services, providing effortless solutions for your bent product needs.

Our tube bending capabilities include:

  • Round
  • Rectangular
  • Square tubing
  • From 1/4” diameter to 4” outside diameter, and
  • Virtually every size tube in between.

Our specialty is custom designed OEM and aftermarket exhaust systems for GAS/LP generators and vehicles. OEM applications include parts for roll-over protection (ROP) on vehicles, specialized panels, and bicycle racks. In construction, tube bending is used for parts of roof trusses, as stringers on bridges, for canopies and circular staircases.

Pipe Bending Equipment

Our use of the most advanced and latest CNC pipe bending equipment and a large bend tooling inventory gives us the flexibility to handle any custom pipe bending or custom tube bending job you may have. Our CNC mandrel bender saves you money and time by producing the custom bent parts you ordered precisely and efficiently. The latest state-of-the-art tube inspection technology verifies that your bent parts were accurately made.

Highly Skilled Technicians

Our skilled staff will work with your engineering team to design your custom tubing needs. We are committed to meeting or exceeding your timelines while providing a high-quality product.

What is Mandrel Bent Tube and Custom Pipe Bending?

With mandrel bent pipe bending machines, a steel plug fits inside the pipe while a rotating steel die forms the pipe to the radius of the die. The steel plug, or mandrel, supports the pipe internally to reduce the amount of pipe cross-section flattening that occurs during custom tube bending and custom pipe bending. A pipe bending clamp secures the pipe to the die. The pipe bending machine rotates the die to the desired bend angle as a sliding pressure die forces the pipe to conform to the die radius. After the custom tube bending and custom pipe bending process, the operator extracts the mandrel from the pipe, releases the clamp and removes the bent pipe from the machine.

With proper tooling, this custom tube and pipe bending process is capable of producing high quality, tight-radius bends for a wide range of applications including football goalposts, davit arms and process piping applications.
