- In accordance to ASTM/ASME A/SA-213
- Tubing sizes are identified by their actual outside diameters “O.D.”, plus or minus applicable tolerances
- Normally furnished as Average Wall “AW”
- All tubes are 20 feet in length but that can vary slightly due to the milling process.
- QTY 1 = 20 FT.
The information presented above are Typical or average values and are not a guarantee of maximum or minimum values.

Working Pressures for T304 & T316, A269 tubing between -20°F and 100°F.
The A.S.M.E. code suggests a safety factor of four. E,G, 1/4″ O.D. x .035 = 5250 P.S.I.
For Higher temperatures multiply working pressure by:
Barlow’s Formula for Theoretical Bursting Pressure
|P = 2 (S * T) / O.D.|
|P – Bursting Pressure (P.S.I.)||T – Wall Thickness (Inches)|
|O.D. – Outside Diameter (Inches)||S – Tensile Strength|
Typical Tensile Strengths (S)
|Stainless Steel (300 Series)||S = 70000 to 75000 psi|
|Chrome Moly (P1 to P5)||S = 55000 psi|
|Chrome Moly (Balance)||S = 60000 psi|
|Alloy 20||S = 80000 psi|
|904L||S = 70000 psi|
|Duplex||s = 90000 psi|
