BaseCalc Plumbing Calculator vs Pipe Offset

BaseCalc Plumbing Calculator is a plumbing calculator for field math, worksheets, materials, and saved calculation history. Run pipe sizing, pressure drop, drainage, vent sizing, water heater, gas pipe, pump head, fixture unit, septic, and other plumbing calculator checks on site, then save the result for the job. 18 CALCULATORS FOR DAILY FIELD WORK • Pipe Velocity — velocity from GPM and nominal pipe size. • Flow Rate — GPM from velocity and nominal pipe size. • Pipe Sizing — minimum pipe size from GPM and max velocity. • Pressure Drop — Hazen-Williams pressure loss. • Drainage Sizing — fixture units to minimum drainage pipe diameter. • Vent Sizing — fixture units plus vent length to minimum vent diameter. • Water Heater — first-hour rating and recovery estimate. • Gas Pipe Sizing — BTU/hr and length to minimum gas pipe size. • Pump Head — total dynamic head from lift, friction, and pressure. • Pipe Volume — gallons of water in a given length of pipe. • Water Pressure — pressure and head conversion. • Pipe Expansion — thermal expansion length change. • Fixture Units — count common fixtures to total fixture units. • Water Meter Sizing — fixture units to meter size. • Irrigation Flow — zone GPM from heads and GPM per head. • Septic Tank — bedrooms and daily flow to minimum tank volume. • Grease Interceptor — fixture units or GPM to interceptor size. • Backflow Pressure — pressure loss across backflow preventer. EVERY RESULT IS EXPLAINED • Clear sizing messages and pass/fail where applicable. • The governing limit, final answer, and calculation breakdown. • Saved local history so you keep a job-site record. JOB RECORDS, MATERIALS, AND WORKSHEETS • Save job contacts with site notes. • Build job worksheets with scope, quantities, and site notes. • Export worksheet PDFs for internal handoff or customer context. • Plan common pull-list items before rough-in, service, and closeout. • Send the finished billing handoff to SpeakSheet for the final invoice. DEVICE-LOCAL FOR THE FIELD • Works offline by default. • No BaseCalc account or cloud sync. • Job contact, worksheet, setting, and calculation data stays on this device, protected by your device security. • There is no BaseCalc cloud option. • Dark and light themes with a high-contrast job-site interface. BaseCalc Plumbing is a professional reference tool. Always verify against current industry standards, manufacturer data, and local codes. The authority having jurisdiction has the final say.

Calculate the pipe cut length between two real fittings. Pipe Offset shows the cut piece, center-to-center travel, fitting deductions and joint gaps together, so you can follow the calculation from layout to cut. Built for pipefitters and steamfitters working with metric or imperial dimensions. Choose EN/DN, ASME/NPS or copper profiles, or enter a custom outside diameter. Fitting values carry source labels: standard, catalogue, theoretical or measured. When a table does not cover your fitting, enter its measured dimensions. OFFSETS AND FITTINGS Solve simple and rolling offsets. With the unlock, select fittings A and B independently at a shared angle, lay out parallel banks with cumulative marks, solve for a target run, or account for an obstacle and clearance. The drawing highlights the cut piece and shows the dimension chain. BRANCHES AND SEGMENTED ELBOWS Lay out branch connections with numbered ordinates for the branch cut and header opening. The unlock adds oblique and eccentric branches, segmented elbows and printable 1:1 PDF templates. Templates tile across A4 or Letter pages with a calibration ruler and overlap marks. Save offsets, branches and elbows as jobs and export PDF cut sheets. INCLUDED WITHOUT PURCHASE Simple and rolling offset calculations, axis dimensions and cut length using the region's default butt-weld elbow family, ASME LR or EN 3D, or your measured fitting values. Also includes one on-screen example of a centered branch at 90°. ONE-TIME UNLOCK One non-consumable purchase opens all included fitting catalogues, independent A/B fitting selection, parallel banks, target-run and obstacle tools, full branch tools, segmented elbows, saved jobs and PDF exports. No subscription. Restore Purchases is available in Settings. Works offline. No account or login. Saved jobs use local app storage.
