Pipe Fitting

Pipe Fitting is a pipe fitter's calculator for offsets, rolling offsets and elbow cuts. Enter the offset and the fitting angle, and it gives you the travel, the take-out of each elbow and the length to cut, with the welder's gap (root gap) already allowed for. Example: a 300 mm offset in DN50 pipe with two long-radius 45° elbows and a 2 mm gap. The travel is 424.26 mm, each elbow takes out 31.07 mm, and you cut the pipe at 358.13 mm. • Basic offset: any two of run, offset and angle give the travel and the cut length, with or without gaps. • Rolling offset calculator: offset, roll and run (or the angle) give the travel and the cut length. • Parallel offsets: the cutback for pipes running side by side. • Back-to-back elbows: X° + Y° and 90° + X° fittings from a centre-to-centre distance, with the angle to cut. • Elbow mitre cut: cut any angle from a standard 90 and mark it, with the outside (heel), inside (throat) and centreline arcs and the chords. • Take-outs for short-radius, long-radius and 3R elbows, from DN6 to DN1200 and 1/8" to 48" NPS. • Triangle solver: any three sides or angles give the rest, plus perimeter and area. • Millimetres, centimetres and metres, or feet, inches and fractions: pick the unit on the keypad. • Results update as you type, and each calculator keeps your last numbers. • On iPhone and iPad. HOW TO CALCULATE A PIPE OFFSET Travel = offset ÷ sin(angle). With 45° fittings that is the offset × 1.414, the 45° offset multiplier; with 22.5° fittings it is × 2.613. Each elbow's take-out = its radius × tan(angle ÷ 2), and the cut length is the travel minus both take-outs and both gaps. For a rolling offset, first find the true offset: √(offset² + roll²). Pipe Fitting does every step for you. Built for pipe fitters, welders, fabricators, boilermakers, plumbers and apprentices, in the workshop or on site.
