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.
Our tube bending capabilities:
- Square Tubing
- From ¼” 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.
Our tube bending capabilities:
Generally, bent tubes are used for structural and, sometimes decorative purposes, or as passageways carrying fluids or gases.
Structural bent tubes include bicycle handlebars, furniture frames, grab bars, roll bars, and more.
Passageways that use bent tubes include hydraulic lines, fuel lines, exhaust pipes, water lines, and more.
Industries that typically using bent tube/pipes are automotive, aircraft, off-road and farm equipment, boiler, air conditioning, ship building, furniture, power generation, recreational vehicle, railroad, etc.
How are tubes bent?
When a tube is bent, the wall which forms the outside of the bend elongates and thins. At the same time, the wall which forms the inside of the bend compresses and thickens. A common objective in tube bending is to form a smooth round bend.
