## What is Field Fitter?

Field Fitter is the field book pipefitters, welders and plumbers keep in their pocket. Every number you reach for on the job, with the math shown so you can check it, and it works with no signal.

WHAT'S INSIDE
• Take-outs and cut-length rules for weld pipe, screw pipe, copper, PVC and CPVC, grooved, cast iron and PEX
• Offsets: simple, rolling and parallel, with the constants and a worked example every time
• 14 calculators, starting with a tape-measure fraction calculator: offsets, cut length, conversions, pipe weight, flow and velocity, volume and fill, grade and fall, right triangles, circumference, thermal expansion, sling loads, temperature and pressure, and fab layout for orange peels, Y cuts and branches. Each one shows its math and draws a 3D picture of what it's working out
• Layout and fabrication: miters, laterals, saddles, orange peels, reducers and templates
• Flanges and bolt-up, valves, threads, gaskets and shop tables
• Rigging: sling angles, hitches, flying pipe, chain falls and crane hand signals
• Testing and startup: hydro, pneumatic and flushing
• Welding and cert prep: test positions, the WPS and your WPQ, bend tests, filler metal and passing the 6G
• Sprinkler fitting (NFPA 13), plumbing DWV and codes (IPC and UPC), HVACR with PT charts and superheat and subcooling, pipeline (49 CFR 192 and 195, API 1104) and conduit bending
• Math, step by step: fractions, triangles, trig and every kind of offset, taught from scratch
• Test prep for the Ohio and West Virginia license exams, the union apprenticeship entrance test and NCCER pipefitting, with practice quizzes that explain every answer and a timed test
• Self-paced lessons, each with a short quiz
• From the Trade: tricks, habits and hard lessons from working hands

BUILT FOR THE JOB
• Works offline once it's on your phone
• Search that knows trade words
• Save pages and get back to recent ones in a tap
• A cut list: add pieces from the calculators and send the list to the saw
• Glove mode, bigger text, dark mode and keep the screen awake
