Pipe Offset Calculator!

Pipe Offset Calculator gives pipefitters, plumbers and electricians the numbers they cut to: rolling offsets, fitting takeouts and the end-to-end cut, flange bolt-up, conduit bends and drainage grade, in big type on a fraction keypad that works in sixteenths.

ROLLING OFFSET

Enter the set (or rise) and roll, pick your fitting angle — 22½°, 30°, 45°, 60°, 90°, or any custom angle — and get true offset, travel and run instantly, with a labeled diagram so you always know which number is which.

SIMPLE OFFSET

Single-plane offsets: one measurement in, travel and run out, drawn to your actual fitting angle.

FITTINGS — THE FITTER'S CUT
• Cut — pick the pipe size (1/2″ to 24″), the fitting on each end (90° LR, 45° LR, 90° SR, tee, a 90 cut to any angle, or your own takeout) and the welder's root gap, then enter the travel: the end-to-end cut comes out with both takeouts and both gaps already off. Pull the travel straight from the Rolling or Offset tab in one tap
• Elbow — cut a 90° long-radius elbow to any angle: the takeout, and the heel, side and throat marks measured from the end you keep
• Bolt-up — Class 150 and 300 raised-face flanges: stud count and diameter, stud length, and the wrench for the heavy hex nut
• Tables — butt-weld takeouts for 90° LR, 45° LR, 90° SR and tees up to 24″, and a sixteenths decimal-to-fraction table
Every takeout and stud number comes from a published catalog to ASME B16.9 / B16.5 and is checked row for row against a second, independent source.

CONDUIT BENDING
The hand-bender math for EMT, on one tab:
• Offset — bend angle 10° to 60°, distance between bends and shrink, and where the first mark goes
• 3-bend saddle — centre and side marks over a pipe or beam, 45° or 60° centre
• 4-bend saddle — all four marks over an obstacle of any width
• 90° stub — mark from the end by conduit size, with back-to-back stubs
Every result shows the bender-table number and the exact trig beside it, so you know what the rounding cost.

GRADE

Drainage slope both directions: run + grade gives you the drop, or run + drop gives you the exact grade — in inches-per-foot and percent, with one-tap presets for 1/8″, 1/4″ and 1/2″ per foot.

BUILT FOR THE JOBSITE
• Every measurement works both ways: feet-inches-sixteenths AND decimal inches — enter either, read both
• Custom fraction keypad with 1/16″ steps and ±1/16″ nudge buttons
• Big result cards — tap any result to copy it
• Save any result; your saved numbers are one tap away on every tab
• One-handed layout, haptic feedback, light and dark
• Works offline — in the basement, the crawlspace and the parking garage
