Working references for specifying and pricing pipework. Everything here is derived from the standards named on each page; where a figure has to be checked against a current copy of the standard, the page says so.
Unit converter
Pressure, flow and temperature between the units this trade quotes in — bar, kg/cm², psi, kPa, MPa — plus the nominal bore table in millimetres and inches.
Flange finder
Drilling dimensions by standard and bore, and where the tables differ — ASME B16.5 Class 150 and 300 against EN 1092-1 PN 10 and PN 16. A valve drilled to one table will not bolt to another.
Pipe weight calculator
Weight per metre and per length for MS and GI tube to IS 1239 Part 1, in light, medium and heavy classes. Useful for freight before the pipe is on a lorry.
Valve selection guide
Tell it the medium, the duty and roughly the bore, and it recommends a valve type and body material — then shows what we stock that matches.
Thread reference chart
BSPP, BSPT and NPT compared by nominal bore — threads per inch and major diameter, and which one is actually cut on our threaded products at that size.
Fire hydrant system estimator
A rough component take-off — landing valves, hose reels, extinguishers — by building occupancy, height and floor area, referencing NBC 2016 Part 4 and IS 3844. A budgeting aid, not a substitute for a licensed fire consultant’s drawing.
