⚠️ These results are for reference only. Always verify with the actual elbow manufacturer's datasheet and on-site measurements before construction. Manufacturing tolerances may cause real take-out values to differ.
The Pipe Elbow Offset Calculator instantly computes elbow take-out and pipe cut length for the three most common piping field scenarios: simple offset (one-direction obstacle bypass), rolling offset (horizontal + vertical movement, 3D), and exact cut length between two connection points. Choose your nominal pipe size (15A–200A) and elbow type (90°/45° long or short radius), and the calculator auto-applies the ASME B16.9 standard take-out value to output the exact cut length you need on site. The tool includes an SVG pipe diagram for visual confirmation and 5% / 10% margin order-length suggestions to absorb installation tolerances.
Common Use Cases
🔧
Obstacle Bypass
When routing around structures or other pipes, enter the offset distance and the cut length between the two elbows is instantly shown. Walk to the cutter with just a tape measure.
🔄
3D Rolling Offset
Rolling offsets (horizontal + vertical at the same time) are the hardest to estimate by hand. Enter horizontal and vertical travel — diagonal Travel distance, tilt angle, and cut length appear automatically.
✂️
Exact Cut Length
For two connection points, you must subtract elbow take-out from the centerline distance. Enter the target distance and connection type — exact cut value displays instantly.
📱
On-site Mobile-first
Just tap the pipe size and elbow type on your phone — take-out is auto-loaded. Large 48px buttons work with gloved hands, so the calculator is usable in any field condition.
How to Use
1
Pick a Pipe Size
Tap your nominal pipe size (15A–200A). The corresponding NPS and ASME B16.9 take-out values are loaded automatically.
2
Pick an Elbow Type
90° Long Radius (LR) is the default for most installations, Short Radius (SR) fits tight spaces. 45° elbows are for gentler direction changes.
3
Pick a Calculation Mode
Simple offset = single-direction bypass. Rolling offset = horizontal + vertical at once. Cut length = exact pipe-cut between two connection points. Inputs are preserved when switching modes.

Enter Numbers, Get Result
Type distances in millimeters and the cut length appears instantly. Check the SVG diagram to confirm the layout, then tap Copy to share with a coworker.
