The app is used in the industrial pipe construction. (American Standard ASME B36.10/ B16.9) Functions: Calculation (imperial and metric) of offsets and weight calculation of pipes, offsets and profiles. All nominal diameter and fittings are provided, so it will be very easy for you to solve complex calculations quickly. Even if you put in false information, you can not get wrong solutions. This way you can save material, time and stress. The App is your help in a hectic and busy working day. - 28 offset calculations (8 offset types with 2 or 4 interrupts) - Given nominal diameters (NPS 1-40/DN 25-1000) according to ANSI/ASME with outside diameter (exemple NPS 5/DN 100- 4.5in/114,3mm), - Calculation with lenght or elbow angle - 2 types of elbow - Manual input of elbow radius - Offsets with tee - Individual gap - Detailed help and description - History of your calculations Results - Cut length - Elbow angle - Inside and outside cutting values of the elbow - Take off, chord - Installation length of offset - Calculation of offset weight Weight calculation of - Pipes, - 2 types of elbow - Channels (C3-C10) - H Beams (W4-W10), - Manual inputs. Single weights will be added to the list, so that you can use the weight of the construction units to choose the right lifting gear.

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 No ads. No subscription. No accounts. Features never move behind a paywall. Built in the U.S.A. by one developer who answers email.
