## What is PipeBase?

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.

### What devices is PipeBase available on?

PipeBase is available for iPhone and iPad devices.

### How much does PipeBase cost?

PipeBase is a paid app, available for a one-time purchase of $0.99.

## Version history (last 2 releases)

### 1.0.1 — 2026-09-04

Bug-fix release from a full on-device QA pass.
• Flange bolt-up diagram now shows the true star tightening sequence
• Trade calculator: +/− applies to the whole feet-inch entry, and ⌫ undoes
  the feet key
• Flange type follows the wheel when a class or size doesn't offer it
• Cleaner dimension captions on Fittings, Flanges and Branch Connections
• Search matches sizes exactly ("sch 80 6" is the 6" pipe)
• Fittings weights no longer wrap on iPhone; landscape puts the wheels
  beside the drawing
• Gaskets listed under Settings → Data sources; per-row flange source label

### 1.0 — 2026-09-02

No release notes.
