Every dimension dual-source verified against the published standards. Buy it once. Works with no signal. Never loses features. The pipefitter's pocket reference and field calculator. Buy it once, use it forever, no signal required. 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. Values that haven't cleared verification are clearly marked. 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): 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 • Rolling offset: set, roll, travel, run — pick a pipe size at 45° and get the end-to-end cut length with takeoffs already subtracted • Miter cuts: cut angle, cutback, heel-to-throat drop, segment lengths • Parallel offset: equal-spread runs through any turn • 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 • Type "6 90" and get the 6-inch takeoffs. "6 150" gets the flange. • 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 No ads. No subscription. No accounts. Features never move behind a paywall. Built in the U.S.A. by one developer who answers email.
