Pipedata has dimensional and weight information for 72 common ASME piping components all in a fast, convenient and easy to use interface. The Pipedata name has been around since 1996, when it was first applied to Pipedata-Pro. Since then it's gained a global presence in the piping industry with large corporations and individuals appreciating the Pipedata hallmarks of accuracy and up-to date relevant information. Based on the latest ASME piping dimensional specifications it shows Metric, US Customary Units and Inch/Fractions and includes audited valve weights, flange weights and all piping component weights. This release is not limited to but includes the following range of information: DATA SUMMARY Pipe ASME B36.10M/19M - 2004 WeldNeck Flange, ASME B16.5-2013 Slip On Flange, ASME B16.5-2013 Blind Flange, ASME B16.5-2013 Threaded Flange, ASME B16.5-2013 SocketWelded Flange, ASME B16.5-2013 Lapped Flange, ASME B16.5-2013 Long Welding Neck Flange, ASME B16.5-2013 Buttwelded 45deg Elbow, ASME B16.9-2007 Buttwelded 90deg Long Radius Elbow, ASME B16.9-2007 Buttwelded 180deg Long Radius Return, ASME B16.9-2007 Buttwelded 90deg Short Radius Elbow, ASME B16.9-2007 Buttwelded 180deg Short Radius Return, ASME B16.9-2007 Buttwelded Equal Tee, ASME B16.9-2007 Buttwelded Reducing Tee, ASME B16.9-2007 Buttwelded Cap, ASME B16.9-2007 Buttwelded Concentric Reducer, ASME B16.9-2007 Buttwelded Eccentric Reducer, ASME B16.9-2007 Buttwelded Lap Joint Stub End, ASME B16.9-2007 Threaded 90deg Elbow, ASME B16.11-2011 Threaded Tee, ASME B16.11-2011 Threaded Cross, ASME B16.11-2011 Threaded 45deg Elbow, ASME B16.11-2011 Threaded 90deg Street Elbow, ASME B16.11-2011 Threaded Coupling, ASME B16.11-2011 Threaded Half Coupling, ASME B16.11-2011 Threaded Cap, ASME B16.11-2011 Threaded Square Head Plug, ASME B16.11-2011 Threaded Hex Head Plug, ASME B16.11-2011 Threaded Round Head Plug, ASME B16.11-2011 Threaded Hex Head Bushing, ASME B16.11-2011 Threaded Flush Bushing, ASME B16.11-2011 Socketwelded 90deg Deg Elbow, ASME B16.11-2011 Socketwelded 45deg deg Elbow, ASME B16.11-2011 Socketwelded Tee, ASME B16.11-2011 Socketwelded Cross, ASME B16.11-2011 Socketwelded Coupling, ASME B16.11-2011 Socketwelded Half Coupling, ASME B16.11-2011 Socketwelded Cap, ASME B16.11-2011 Socketwelded Reducing Coupling, ASME Unadopted Socketwelded Welding Boss, ASME Unadopted Socketwelded Reducing Insert Type 1, ASME Unadopted Socketwelded Reducing Insert Type 2, ASME Unadopted Socketwelded Reducing Insert Type 3, ASME Unadopted Socketwelded Union, ASME Unadopted Socket Details, ASME B16.11-2011 Non Metallic Flat Ring for ASME B16.5 Flanges, ASME B16.21-2011 Non Metallic Flat Ring for ASME B16.47 Series A Flanges, ASME B16.21-2011 Non Metallic Flat Ring for ASME B16.47 Series B Flanges, ASME B16.21-2011 Spiral wound for ASME B16.5 Flanges, ASME B16.20-2012 Spiral wound for ASME B16.47 Series A Flanges, ASME B16.20-2012 Spiral wound for ASME B16.47 Series B Flanges, ASME B16.20-2012 RTJ Soft Iron Ring type R, ASME B16.20-2012 RTJ Soft Iron Ring RX, ASME B16.20-2012 RTJ Soft Iron Ring BX, ASME B16.20-2012 Flanged Gate Valve, ASME B16.10-2009 Flanged Globe Valve, ASME B16.10-2009 Flanged Ball Valve, ASME B16.10-2009 Flanged Control Valve, ASME B16.10-2009 Flanged Swing Check Valve, ASME B16.10-2009 Flanged Wafer Check Valve, API 594 Wafer type Butterfly Valves, ASME B16.10-2009... and much more: Check it out!

Verdict
The clearest difference is in-app purchases: Pipedata at none against DWG FastView's 9. Pipedata also leads on ads (none vs shown) and iOS requirement (11.0 vs 13.0). DWG FastView's advantage is ratings volume (1.1K vs 44) and review sentiment (69% vs 52%). On price, rating, update cadence and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. DWG FastView sells 9 in-app purchases, starting at $0.99 per month. Pipedata asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 4.5 for DWG FastView against 4.4 for Pipedata. That said, the two scores are not equally well evidenced: DWG FastView has 1.1K ratings behind it against 44, so its average is the more settled of the two. Written reviews are what separate them: 69% of DWG FastView's written reviews are positive against 52% of Pipedata's.
DWG FastView ships an update every 4 weeks, Pipedata every 3 weeks. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
