Tube pressure calculator: rate any stainless or alloy tube in seconds
Use this tube pressure and wall-thickness calculator to work out the allowable working pressure, burst pressure, and minimum required wall thickness of stainless-steel and high-nickel/CRA instrumentation tubing. You just need four inputs: outside diameter (OD), wall thickness, material grade, and service temperature. The tool applies Barlow's formula for a quick pressure estimate, then runs the ASME B31.3 internal-pressure equation for a code-form wall-thickness solution. From there it adjusts for mill under-tolerance and a design safety factor. The engineering constants are already built in, the ASME B31.3 allowable-stress S-values, plus the E, W, and Y coefficients, all cited below. So what you get back is a real number, not a placeholder.
Crestflo compression tube ends set the ceiling here: read this scope note before you use the calculator. It covers fluid-system instrumentation tubing only, stainless and alloy, seamless or welded, built to ASTM A269 / A213, and it's sized by actual OD, up to 2" (50 mm). Structural tube isn't included. Neither is medical or catheter tubing, nor plumbing pipe. The numbers you get rate mechanical pressure containment; they say nothing about pressure drop or flow. And treat the output as an estimate, not a stamped engineering calculation. Every design pressure needs to be checked against the governing code, PED included, by a qualified engineer before you rely on it.
The calculator
Modes (tab selector inside the widget):
- Pressure from wall: enter OD, wall and material, and you'll get the allowable working pressure (MAWP), a burst estimate, the resulting hoop stress, the derating factor applied, and the safety factor. (Covers: tube pressure calculator, tubing pressure calculator, tube pressure rating calculator, allowable working pressure calculator, working pressure of tubing calculator.)
- Wall from pressure: feed in design pressure, OD and material. The tool solves the ASME B31.3 equation for minimum, or required, wall thickness, then tacks on mill under-tolerance and allowances. See wall mode.
- Burst estimate, Barlow with ultimate tensile strength. See burst mode.
Pipe / Barlow mode, Barlow calculated from OD for pipe, used for the related "pipe pressure calculator" query. See pipe mode.
Units: switch between imperial (in / psi) and metric (mm / bar). This is the path people mean by "tube pressure calculator metric" and "steel tube pressure calculator." Numbers update on the fly; you won't need to reload the page. The conversions rest on precise constants: 1 psi equals 0.0689476 bar, and 1 in equals 25.4 mm.
> Every output here is an estimate. Check it against a stamped calculation and the governing code before you build. Nothing here replaces that step. For allowable working pressure, the tool relies on the ASME B31.3 basic allowable stress S, which already carries the code's own built-in safety margin (see below). The burst-to-working reduction is different: it uses a default 4:1 design factor, a figure common for instrumentation tubing, and you're free to change it within the tool.
Designations & related terms. People search for this tool under a lot of different names: tube pressure calculator, tubing pressure calculator, tube pressure rating calculator, tubing pressure rating calculator. Others look for tube wall-thickness calculator, tubing wall thickness calculator, minimum wall thickness calculator, or required wall thickness calculator. Some want a tube burst pressure calculator, plain and simple; others just type burst pressure calculator. Then there's the working-pressure crowd: allowable working pressure calculator, maximum allowable working pressure (MAWP) calculator, working pressure of tubing calculator. A fair number search for Barlow's formula calculator or tube hoop-stress calculator instead. You'll also see tube pressure rating chart and stainless steel tubing pressure rating come up often. Pipe terms overlap too: pipe pressure calculator, pipe wall thickness calculator. And steel / hydraulic tube pressure calculator shows up alongside more specific queries like tube pressure calculator metric and tube pressure calculator PDF / Excel.
How the calculation works: Barlow's formula & ASME B31.3
The calculator was built to be transparent on purpose. It shows you the equations and the constants right there, instead of burying them inside a black box.
Barlow's formula (working-pressure estimate)
Barlow's formula ties internal pressure to wall thickness, with the tube's outside diameter as the link between the two:
P = (2 · S · t) / D₀
where P = pressure, S = allowable stress of the material, t = wall thickness, and D₀ = outside diameter. Rearranged for wall, t = (P · D₀) / (2 · S). This is the fastest, most widely published tube-rating relationship and is the basis of the "barlow formula calculator" and "barlow's formula" queries.
Hoop (circumferential) stress
Internal pressure creates a hoop (circumferential) stress in the tube wall, and it works out to σ = (P · D₀) / (2 · t). Barlow's approach is straightforward: set that hoop stress equal to the allowable stress S, then solve for pressure. That's the whole reason the two equations mirror each other. The tool reports the resulting hoop stress, letting you check it against the material's allowable stress. (Covers: tube hoop stress calculator, hoop stress, circumferential stress.)
ASME B31.3 minimum-wall equation
The calculator arrives at a code-form wall-thickness solution using the internal-pressure equation for process piping laid out in ASME B31.3.
t = (P · D₀) / (2 · (S·E·W + P·Y))
Then adds mill under-tolerance plus any corrosion or mechanical allowance. Symbol definitions and the standard coefficient values sit in the reference tables below. This covers "asme b31.3 pressure calculator" and "asme b31.3 wall thickness formula." For the full standard, see the ASME B31.3 minimum wall-thickness rules page.
Burst-pressure estimate
Burst pressure comes from the Barlow equation, using the material's ultimate tensile strength (UTS) in place of the allowable stress. Divide that result by the design safety factor to get the allowable working pressure. See the burst mode. (Covers: tube burst pressure formula.)

Allowable-stress (S) values: the constants the calculator uses
Material only changes one variable: the basic allowable stress S. ASME B31.3 Table A-1 publishes these values, drawn in turn from ASME BPVC Sec. II-D, and the tool ships with them built in already. For austenitic stainless, the code sets S at whichever is lower: UTS ÷ 3.5, or ⅔ of the specified minimum yield. The representative figures below, at ≤100 °F, follow that same basis. This is the data behind "stainless steel tubing pressure rating," "316 stainless tubing pressure rating," and "allowable stress for 316 tube."
| Alloy | UNS | Min. UTS (ksi) | Min. yield (ksi) | Basic allowable stress S at ≤100 °F (ksi) |
|---|---|---|---|---|
| 304 | S30400 | 75 | 30 | 20.0 |
| 304L | S30403 | 70 | 25 | 16.7 |

| Monel 400 | N04400 | 70 | 28 | 18.7 |
UNS designations and minimum UTS/yield are standard published values (ASTM A269/A213/A789/A790/B distributed alloy specs). S at ≤100 °F is computed on the ASME B31.3 basis [lower of UTS÷3.5 or ⅔ yield]. Values per ASME B31.3; confirm against the current edition for your service, and note the code lists some austenitic grades at a higher stress where slightly greater deformation is acceptable. Full grade data on the materials pages. Values customizable to requirement.
Temperature derating. As temperature climbs, allowable stress drops. That means S(T), and MAWP right along with it, derates even though the geometry doesn't change. Below are representative 316/316L values per ASME B31.3 Table A-1:
| Temperature | 316/316L allowable stress S (ksi) | Derating factor vs ≤100 °F |
|---|---|---|
| ≤100 °F (38 °C) | 16.7 (316L) / 20.0 (316) | 1.00 |
| 200 °F (93 °C) | 16.7 / 20.0 | 1.00 |
| 400 °F (204 °C) | 15.8 / 18.9 | 0.95 |
| 600 °F (316 °C) | 13.9 / 16.6 | 0.83 |
| 800 °F (427 °C) | 13.3 / 15.9 | 0.80 |
Representative values per ASME B31.3 Table A-1; the tool reads the exact S(T) at your entered temperature. Confirm against the current edition for your service. The engineering of why a rating derates is on the pressure-temperature derating guide.
Inputs explained
Four inputs drive the result:
Pull your outside diameter (OD) and wall thickness from the tubing size chart, which lists the valid OD × wall combinations, or straight off your tube's mill certificate. Before rating, the tool trims the nominal wall down by the applicable mill under-tolerance (per ASTM A269/A213). That's because the thinnest legal wall is what actually governs.
- Material grade, sets the allowable stress S from the table above. See rating by alloy.
- Temperature, sets S at temperature and the derating factor. See temperature derating.
Seamless tubing uses a joint factor of E = 1.0. Welded tubing comes in under that, E < 1.0, typically 0.85 as-welded per spec, and that's what brings the pressure rating down on welded tube. (Covers: seamless tube pressure rating, welded tube pressure rating.)
Standard tube OD & wall sizes
The calculator works with the standard published outside diameters and wall gauges for instrumentation tubing, covering both fractional and metric sizes. For exact dimensions, check the tubing size chart.
| Standard sizes | |
|---|---|
| Fractional OD (in) | 1/16, 1/8, 3/16, 1/4, 5/16, 3/8, 1/2, 5/8, 3/4, 7/8, 1, 1-1/4, 1-1/2, 2 |
| Metric OD (mm) | 3, 6, 8, 10, 12, 14, 15, 16, 18, 20, 22, 25, 28, 30, 32, 38, 50 |
| Fractional wall (in) | 0.028, 0.035, 0.049, 0.065, 0.083, 0.095, 0.109, 0.120, 0.134, 0.156, 0.180, 0.220 |

Standard instrumentation tube sizes per ASTM A269/A213 practice; Crestflo supplies OD up to 2" (50 mm). Sizes customizable to requirement.
Minimum / required wall-thickness calculator
Switch to wall mode when you need to size a tube against a known design pressure. Enter the design pressure, OD, material and temperature, and the tool solves the ASME B31.3 equation for the minimum required wall thickness. It then adds mill under-tolerance and any corrosion or mechanical allowance, so the delivered tube still passes even at its thinnest legal wall. This is the path for the "minimum wall thickness calculator," the "required wall thickness calculator," and the "tube wall thickness calculator." Want the theory behind it, plus worked examples? Check the full tube-sizing and wall-thickness guide.
Tube burst pressure calculator
Burst mode figures out the pressure at which the tube actually ruptures, using Barlow's equation and the material's ultimate tensile strength. Divide that burst value by a design safety factor and you get the allowable working pressure. Instrumentation tubing commonly uses a 4:1 factor, though the tool lets you set your own. Burst is a failure limit, never a working one. Design to the derated allowable working pressure instead, always. (Covers: tube burst pressure calculator, burst pressure calculator, tube burst pressure formula.)
Worked example: 1/2" × 0.065" 316/316L at 100 °F
- Inputs: OD D₀ = 0.500", nominal wall t = 0.065", material 316/316L, T = 100 °F.
- Allowable stress: S = 16,700 psi (316L governs the dual-certified pair at ≤100 °F, ASME B31.3 basis, see S-value table).
- Reduce for mill under-tolerance: ASTM A269/A213 allow a wall under-tolerance, commonly around 10% for small instrumentation tube. Design wall works out to 0.065 × 0.90 = 0.0585".
- Barlow working pressure: P = 2 · 16,700 · 0.0585 / 0.500 = ≈ 3,910 psi. That's the allowable working pressure, and it comes out to roughly 270 bar.
- Burst estimate: P_b = 2 · 75,000 (min UTS, 316) · 0.065 / 0.500 = 19,500 psi.
- Check the margin: divide burst by working, roughly 19,500 by 3,910, and you land near 5:1. That's comfortably above the 4:1 instrumentation default. The working figure already accounted for the derated code stress and the reduced wall, which is why the number comes in this high.
At nominal wall thickness, with no reduction for tolerance, the Barlow working pressure works out to roughly 4,340 psi. The tool doesn't default to that number, though; it uses the more conservative reduced-wall figure instead. (All the numbers here are computed from the cited constants: S per ASME B31.3, UTS per ASTM A269. Check these against the current edition for your service.)
Tube pressure rating chart
This is a static, HTML-native tube pressure rating chart. Crawlers and AI engines can pull the ratings straight out, even with JavaScript turned off. It's also useful as a printable reference, covering the "tube pressure calculator PDF" and "tube pressure rating chart" ask. Allowable working pressure and burst estimate are listed by common OD × wall for a 316/316L baseline at ≤100 °F; other alloys scale by their allowable stress (see rating by alloy).

Allowable working pressure computed from Barlow at nominal wall with S = 16,700 psi (316/316L, ASME B31.3 basis, ≤100 °F); burst estimate from Barlow with min UTS = 75,000 psi (ASTM A269). For elevated temperature apply the derating factor; for a delivered-tube figure the tool reduces wall for mill under-tolerance. Values per ASME B31.3 / ASTM A269; confirm against the current edition for your service. See 316/316L allowable stress. Sizes customizable to requirement.
Heavy-wall note: Barlow's formula is a thin-wall approximation. It grows more conservative as wall thickness approaches D₀/6. This calculator runs on the Barlow / ASME B31.3 thin-wall basis, which fits standard instrumentation tubing well. Heavy-wall and high-pressure cone-and-thread sizes aren't covered by that basis; they're rated using the thick-wall (Lamé) method instead. For ratings on those sizes, request a quote. Values follow the applicable standard, and we can tailor them to your requirement.
Pressure rating by alloy: stainless, duplex & nickel tube ratings
Alloy choice changes just one variable in Barlow: the allowable stress S. A higher-strength alloy at the same OD and wall thickness carries a proportionally higher pressure rating. Take the 316/316L figures in the rating chart and multiply them by the ratio of the alloy's S to 16.7 ksi, found in the S-value table. That's the answer to "alloy tube pressure rating," "nickel tube pressure rating," and "Inconel / Monel / Hastelloy / duplex tube rating."
| Alloy | UNS | S at ≤100 °F (ksi) | Rating vs 316/316L (×16.7 ksi) | Tubing page |
|---|---|---|---|---|
| 304 / 304L | S30400 / S30403 | 20.0 / 16.7 | 1.20× / 1.00× | 304/304L |

UNS numbers are standard published designations; S computed on the ASME B31.3 basis from ASTM minimum tensile/yield (see S-value table). The "rating vs 316/316L" multiplier applies to the same OD and wall at ≤100 °F. Also supplied as tubing: AL-6XN, Alloy 20, Inconel 600/601/718, Incoloy 800/800H, Monel K500, Hastelloy C-22/B-2/B-3/X, Nickel 200/201 and Titanium Gr2. Full material data on the materials pages; unsure which alloy? Use the alloy selector. Values per applicable standard; customizable to requirement.
Pipe pressure calculator (Barlow mode)
For pipe, not tube, switch over to pipe mode. Pipe gets specified by NPS and schedule; tube by actual OD. The underlying Barlow relationship stays the same either way: P = 2·S·t / D₀, applied to the pipe's OD and wall. This covers the related "pipe pressure calculator," "pipe wall thickness calculator," "pipe burst pressure calculator," and "how to calculate psi in a pipe" searches. For seamless and welded stainless pipe product specs, see ASTM A312. (One distinction worth noting: NPS/schedule isn't the same as tube OD. Instrumentation runs use tube, not pipe.)

Frequently asked questions
How do you calculate the pressure rating of a tube?
Start with Barlow's formula, P = 2·S·t / D₀. Allowable working pressure works out to twice the material's allowable stress (S), multiplied by wall thickness (t), then divided by outside diameter (D₀). Before running the numbers, trim the wall for mill under-tolerance and apply a design safety factor. For 316/316L at 100 °F or below, S comes in at 16,700 psi, on an ASME B31.3 basis.
How do I "calculate a tube", what inputs do I need?
You need four things: outside diameter, wall thickness, material grade (this sets the allowable stress), and service temperature. Enter them into the calculator, and it runs the Barlow formula alongside the ASME B31.3 wall equation, pulling in the built-in S / E / W / Y constants automatically.
How do I calculate psi in a pipe?
Same Barlow relationship, applied to the pipe's OD and wall. Switch the tool to pipe mode and enter the NPS/schedule wall; pipe mode works off NPS/schedule, while tube mode uses the actual OD.
What is the difference between working pressure and burst pressure?
Burst is the pressure at which the tube actually fails, calculated using Barlow's formula with the ultimate tensile strength. Allowable working pressure is burst divided by a design safety factor, commonly around 4:1. Always design to the working pressure, not the burst figure.
What is the pressure rating of 316 stainless steel tubing?
Rating depends on OD, wall thickness and temperature; check the rating chart for specifics. Take 1/2" × 0.065" 316/316L as an example: it's rated at roughly 4,340 psi at nominal wall, up to 100 °F. For instrumentation work, 316/316L is the standard baseline, with S = 16,700 psi under ASME B31.3.
Does temperature lower a tube's pressure rating?
Yes, it does. As temperature climbs, allowable stress drops, so MAWP derates accordingly. The calculator handles this with the temperature factor (e.g. ≈0.83 for 316 at 600 °F). For more detail, check the derating guide.
How do I find the minimum wall thickness for a design pressure?
Head to wall mode. Enter the design pressure, OD, material and temperature, and the tool takes it from there. It solves the ASME B31.3 equation for required wall, then tacks on mill under-tolerance and allowances.
Does this calculate pressure drop or flow?
No, it doesn't. This tool rates mechanical pressure containment: wall strength against internal pressure. Pressure drop and flow through the tube are separate calculations entirely. Need "pressure drop per 100 ft"? Reach for a flow calculator instead, not this one.
Which alloys does the calculator support?
304/316/904L, duplex 2205 and super duplex 2507, 254 SMO, AL-6XN, Alloy 20, Inconel/Incoloy/Monel/Hastelloy grades, Nickel 200/201 and Titanium Gr2. These are the alloys Crestflo supplies as tubing, and each one comes with its ASME B31.3 allowable stress already built in.
Is this a stamped engineering calculation?
No. The results are estimates meant for selection and checking. A qualified engineer must confirm the final design pressure against the governing code. Crestflo's Engineering Team reviews the formulas and the allowable-stress constants, including those tied to PED.
Can I get the rating table as a PDF or Excel?
You can print or export the static HTML rating chart directly, no special format needed. Need something built around a particular project instead? Request a quote.
