Product Engineering

Tube Fab/Roman Engineering offers comprehensive product design support. We work with our clients to help them design high quality fabricated tubes and tube assemblies that are manufactured in a cost effective manner.

We have helped clients by:

  • Proposing design changes that improve the customer assembly process, saving time, and improving quality.
  • Suggesting design changes that improve the performance and life cycles of their products.
  • Advising changes to material specifications to lower cost while maintaining engineering and quality integrity .
  • Suggesting design changes that simplify the manufacturing process and reduce costs.
  • Recommending tube diameter and wall thickness of standard mill sizes to reduce both cost and lead time.

We take great care to understand your needs, the part and its function – then we apply our years of tube fabrication experience to provide superior solutions by design.

Tube Design Guidelines

Tube Fab/Roman Engineering offers comprehensive product design support. We work with you to help design high quality fabricated tubes and assemblies that can reduce your costs.

Metal Tubing Material

  • Use of standard mill size metal tubing reduces lead time and saves on material cost.
  • Standard material content specifications also reduce lead time and save on material cost.
  • Custom tube sizes and wall thicknesses may reduce process steps in certain applications.

Tube Cutting

Standard cut length tolerances at normal production speeds

Tube Bending

Minimum bend radius using standard bend tooling is 1.5 times the tube diameter.
We produce custom bend tooling that reduces the minimum bend radius to a 1:1 ratio - or less, depending on material and tolerance specifications

Tube End Forming

  • Use of SAE guidelines for metal tube end form design typically result in tube designs that can be made in a cost effective manner.

Our years of metal tube fabrication experience have shown that there are many exceptions to the guidelines listed above. Our product engineers would be pleased to talk with you about your design.

We take great care to understand your needs, the part and its function – then we apply our experience to provide superior solutions by design.

  • ± .003” (.076mm) on lengths up to 6.000” (152.4mm)
  • ± .005” (.127mm) on lengths up to 12.000” (304.8mm)
  • ± .010” (.254mm) on lengths up to 24.000” (609.6mm)
  • ± .020” (.508mm) on lengths up to 36.000” (914.4mm)
  • ± .125” (3.175mm) on mill lengths

Part Fabrication Chronology

The fabrication of a dipstick tube assembly begins with a cut-to-length metal tube – snap cut, and burr free for the next operation.
The tube is then beaded, expanded and flared using custom tooling made by our in-house toolmakers.
Next, the tube is roll-grooved to hold an o-ring, which will be added later in the process.
A multi-plane (XYZ coordinate) tube bending operation is completed, using custom tooling made by our in-house toolmakers.
A stamped metal bracket is manufactured.
The bracket is aligned and projection welded to the tube.
The nearly completed fabricated tube assembly is painted.
The o-ring is assembled and the dipstick is inserted into the tube.
A final audit inspection is performed and the completed dipstick tube assembly is packaged for shipment to the customer’s plant.
