Pipe Trades Pro Calculator

Pipe Trades Pro is the rolling offset calculator and pipe fitting calculator for pipefitters, steamfitters, sprinkler fitters, and welders. Professional pipe trades math for commercial and industrial jobsites. Rated 4.7 stars on Google Play. Pipe Trades Pro is the pipe trades calculator built for the field, not the office. Solve rolling offsets, cut lengths, NPT thread engagement, drain slope, and pipe fitting math in seconds. No decimal conversion, no guesswork, no callbacks to the shop. Built with the same core engine that powers Calculated Industries' industry-standard construction-math calculators. Award-winning tools trusted by the trades for 40 years. Every calculation verified against real pipe trade math. BUILT FOR THE JOBSITE • Pipefitters and steamfitters solve rolling offsets, odd-degree fittings, and cut lengths in seconds. • Welding functions handle weld cutback, setback, fitting layout, and pipe segment math. • Sprinkler fitters use Pipe Trades Pro for offsets, drain slope, and pipe run layout. • Journeymen and apprentices get built-in pipe data for all trade sizes and materials. ROLLING OFFSET CALCULATOR • Rolling offset calculator solves any offset in seconds, for any angle and any pipe size. • Automatic travel, set, and run from any rolling offset input. • Parallel rolling offset calculator handles multiple pipelines with cutback and spacing. • Odd-degree rolling offset supports any non-standard pipe configuration. PIPE FITTING CALCULATOR • Pipe fitting calculator covers elbow takeout for 90°, 45°, and any custom fitting angle. • NPT thread engagement length and thread makeup for all standard pipe sizes. • Fitting allowances and cut lengths for every standard fitting type. • Take-outs, setbacks, and fitting-to-fitting dimensions solved in one calculation. WELDING FUNCTIONS • Welding functions handle weld cutback and setback for pipe segment prep and joint layout. • Pipe segment dimensions and fitting layout for spool fabrication. • Full trig functions cover miter cuts, odd-angle welds, and compound pipe runs. • Pipe schedule and material reference for weld prep across all standard trade materials. FIRE SPRINKLER AND DRAIN LAYOUT • Sprinkler fitter offset and pipe run layout for fire sprinkler system design. • Drain slope calculator covers any grade, drop, or distance. • Pipe sizing and flow calculations for fire suppression and mechanical system layout. FLUID DYNAMICS AND PRESSURE ANALYSIS • Fluid dynamics calculator computes flow rates, velocity, force, and volume for multiple fluids. • Pressure loss covers any pipe size, material, and distance. • Supports water, steam, compressed air, and hydraulic fluid calculations. PIPE DATA REFERENCE • Pipe data covers sizes up to 42 inches: steel, stainless steel, brass, copper, and aluminum. • Internal area, filled weight per foot, wall thickness, and schedule reference built in. • Seven materials with full dimensional data across all standard sizes and schedules. INPUT AND COMPATIBILITY • Feet-inch-fractions input throughout, no decimal conversion required. • Full imperial and metric unit support. • Works offline; all pipe data and calculations are available without cell service.
