PipeBase: Pipe Fitter Charts

The piping reference that field crews and designers actually need — every
lookup driven by a live dimensioned drawing, working entirely offline.

SEVEN MODULES
• Pipe Schedule — ASME B36.10M & B36.19M, NPS 1/8"–48", every schedule
including stainless 5S–80S, with a built-in length calculator for
surface area, volume, and water-filled weight
• Fittings — B16.9 butt-weld (elbows, tees, reducers, caps, stub ends)
and B16.11 forged socket-weld & threaded, classes 3000/6000/9000
• Flanges — B16.5 Class 125–2500 plus B16.47 Series A & B through 48",
with drilling, bolting, and weights
• Valves — B16.10 face-to-face and end-to-end for gate, globe, check,
and ball valves, RF/BW/RTJ
• Branch Connections — MSS SP-97 Weldolet, Sockolet, Thredolet
• Line Blanks — B16.48 spectacle blinds, paddle blanks, and spacers
• Gaskets — B16.21 flat ring and full face with drilling

BUILT FOR THE FIELD
• Global search: type "2 300 wn" and jump straight to the 2" Class 300
weld neck flange
• Tap any drawing to flip decimal ⇄ trade fractions (nearest 1/16")
• Inch/mm everywhere, NPS or DN, your choice
• Pressure–temperature ratings per class (material group 1.1)
• Bolt-up data: stud counts and sizes, torque-per-stress tables, and a
star-pattern tightening sequence drawn for your flange's bolt count
• Feet-inch-sixteenths trade calculator with memory
• Favorites, recents, side-by-side schedule comparison, and shareable
datasheets with standard citations
• 100% offline — nothing to sign into, nothing tracked, no ads

EVERY NUMBER VERIFIED
Dimensional data is compiled from published tables of the governing
ASME/MSS standards and locked by automated cross-checks against
independent sources. Every value cites its standard. Always verify
critical dimensions against the current standard edition before
fabrication.
