4130 Streamline Tube

 

HIGH PERFORMANCE STREAMLINE TUBE

For several years, A.E.D. has offered the following previously unavailable sizes of custom streamline “aerotube.”

They are produced by roll-forming ROUND tubes through a series of rollers and dies.  This process is cold-rolled, and no further processes (such as stress-relieving) are performed afterwards.

The round tubes can be 4130,  Docol, Mild Steel, Aluminum, Titanium (“CP” Grade is preferred), or Stainless Steel.

Wall thicknesses can range from .032 – .065, based on availability of round material.

Minimum order is 6 feet of the round material.  Leadtime is typically 1 day for in-stock material.

There are no tolerances on the finished dimensions. The major and minor are going to be close to the listings, but the type and grade of material are going to affect the finished results, as well as the wall thickness.

There are no material test reports (sometimes referred as “material certifications”) available for the finished roll-formed material.  Test reports are available for most of the original round tubes at an additional cost. Be sure to discuss with your sales representative.

NOTES:
The smaller sizes tend to be more in an OVAL shape rather than the STREAMLINE shape.  This is due in part to the smallness of the dimensions and the way the tooling operates.

None of these custom tubes are kept in stock.

They are produced to order only.

Minimum order is one length of ROUND material.

TRADITIONAL STREAMLINE TUBE

Up until recently, we stocked several sizes of traditional 4130 Streamline Tubing (also referred to as “Aerotube” or “teardrop shaped tube”).  These sizes have gotten difficult to source and very expensive.

Typical Mechanical Properties:
Condition F (hardened and tempered)

Tensile Strength (psi) 125,000 min
Yield Point (psi) 100,000 min
Elongation (% in 2″) 17 min
Reduction of Area (%) 55 min
