PipeDexa: Pipe Data & Flanges

PipeDexa is an offline piping handbook and pipe data app: pipe schedule chart, flange dimensions, pipe fitting dimensions, flange bolt chart and pipe weight calculator, with a dimension drawing, a 3D model and the public source of every value. Made for piping engineers, designers, pipe fitters, welders, fabricators, QC inspectors, estimators and students.

WHAT THIS APP OPENS: 27 COMPONENT TYPES, 3,000+ SIZES

• Pipe schedule chart for carbon, alloy and stainless steel pipe (ASME B36.10M and B36.19M pattern): outside diameter, wall thickness and inside diameter by schedule (Sch 10, 40, 80, 160, STD, XS, XXS, 10S, 40S…), weight per metre or per foot. Pipe sizes in NPS and DN, in mm and inches.

• Pipe fitting dimensions for butt-weld fittings (ASME B16.9 pattern): 90° and 45° long-radius and 90° short-radius elbows, equal and reducing tees, concentric and eccentric reducers and caps, with the weight for the pipe schedule you pick.

• Flange dimensions (ASME B16.5 pattern, Class 150 to 2500) for weld neck, slip-on, socket weld, threaded and blind flanges: outside diameter, thickness, bolt circle and weight.

• Flange bolt chart: number and size of bolts, stud bolt length and nuts per joint for each flange size and class.

• Forged socket-weld and threaded elbows, tees and couplings; spiral-wound and flat gaskets; valve face-to-face lengths.

• Tools: pipe weight calculator (with contents and insulation), unit converter and NPS ↔ DN chart.

HOW IT WORKS

• Search the way you talk: "6 sch 40 elbow", "4in 300# WN", "DN100 blind".

• A clear dimension drawing for every component, each letter linked to its value; pinch to zoom, full screen.

• A 3D model with section view, orbit and zoom.

• Weight, bolts and nuts at a glance under every drawing; add sizes to a take-off list.

• mm and inches with fractions; 3 colour themes, each in light and dark.

EVERY VALUE WITH ITS SOURCE

PipeDexa compiles 3,800+ sizes of 39 piping component types from 51 public manufacturer and distributor sources (38 publishers); this app opens 3,000+ of them. Each value is marked verified (two independent publishers agree), single source or conflict, with the documents listed. A value that is not in the data is shown as missing, never guessed.

ADS AND USAGE STATISTICS

This app shows ads from Google AdMob: a banner on the main screens and, now and then, a full-screen ad between pages. It sends usage statistics (Google Analytics for Firebase), which you can turn off in Settings.

QUICK ANSWERS

• Is PipeDexa free? Yes: ads pay for it, and there are no in-app purchases.

• Can I remove the ads? For 24 hours with an optional short video, or for good with PipeDexa Pro, a separate one-time purchase with no ads.

• Does it work without internet? Yes, with no account: the reference data, drawings and calculations are on your phone.

MORE IN PIPEDEXA PRO

PipeDexa Pro, a separate one-time purchase on Google Play with no ads, opens all 39 component types, adding large-diameter flanges up to NPS 60 (ASME B16.47 Series A and B pattern), lap-joint flanges and stub ends, 180° returns, crosses, weld, socket-weld and threaded branch outlets, ring-joint gaskets and spectacle blinds. It adds every tool (flange bolt kit, pipe section properties, material weight, paint and insulation area), DXF export for CAD, SVG and A3/A4 drawing sheets, GLB/STL/OBJ 3D models, CSV, unlimited take-off lists, size comparison, design mode and all 10 colour themes.

Reference data only: verify critical dimensions against the current edition of the governing standard or the manufacturer's certified drawing before fabrication. Weights are reference estimates. Pattern names such as "ASME B16.5 pattern" identify the dimensional pattern only; PipeDexa is not affiliated with or endorsed by ASME, MSS, API or ASTM.
