PipeBook Pipefitter Calculator 1.1.0

The pipefitter's pocket reference and field calculator. One purchase, no subscription, no account. Yours.

REFERENCE: verified, not scraped

Every dimension in PipeBook is extracted from two independent published sources, machine-compared, and hand-resolved against a third before it ships. The handful of values that haven't cleared that process are marked in the app, in plain sight, rather than quietly shipped. No guesses, no filler.

• Pipe schedules (ASME B36.10M/B36.19M): wall, ID in decimals and 16ths, weight per foot. NPS 1/8 to 48, Schedule 5 through XXS
• Fitting takeoffs (ASME B16.9), the takeouts on the print: 90s and 45s (LR and SR), tees, concentric and eccentric reducers, caps, stub ends, 1/2 to 24
• Flanges (ASME B16.5, classes 150/300/600): OD, thickness, bolt circle, hub, length thru hub, plus the full bolt-up: stud count, diameter, and length (RF and RTJ) and B16.20 ring gasket numbers

CALCULATORS: fraction-native, in 16ths, 32nds or 64ths
• Rolling offset: set, roll, travel, run. Pick a pipe size and get the end-to-end cut length with the takeoffs and your welder's root gap already subtracted
• Cut a fitting: any angle out of a factory 90, with the heel, centerline and throat marks
• Miter cuts: cut angle, cutback, heel-to-throat drop, segment lengths
• Parallel offset: equal-spread runs through any turn
• Right angle: any two of set, run, travel or angle gives the rest, with grade in percent and inches per foot
• Weight & fill: pipe, plate and tube weight, and what the line holds. Pounds and gallons per foot of water, for rigging and hydro
• Feet & inches: running tape math that accepts 3' 4 1/2 and never loses a 16th

BUILT FOR THE FIELD
• Works completely offline. No license checks, no sign-in, nothing to time out in a basement or on a pipeline right-of-way
• Send the welder the cut: the text and a dimensioned diagram, straight out of the calculator, with the root gap it assumed printed on the drawing
• Type "6 90" and get the 6-inch takeoffs. "6 150" gets the flange. "dn150" works too
• Metric: one switch and every calculator takes and gives millimetres. Tables show mm, kg/m and DN
• Pin your job's sizes; your recent lookups stay one tap away
• Screen stays awake while a table is open
• Big targets that work with gloves on
