Ever been in the field, a meeting or someones office and needed to check a pipe or flange rating. If so this is app for you. Calculations are based on the ASME B31.3 2008 Process Piping code. Piping and Flange Calculator determines the required pipe schedule and ANSI flange rating based on the user inputted pressure, temperature, and corrosion allowances. The results screen shows complete calculation details including both the calculated thickness, minimum suggested pipe schedule, stress value, pressure, temperature, and corrosion allowances. It contains a wide of pipe sizes (1/2" to 24") and database of materials (carbon and stainless steel) including: SA-106B-SLMS SA-333-6 SMLS SA-333-6 Welded SA-312/TP304L SA-312/TP304L: Welded,EFWT-DBS SA-312/TP304L;Welded,EFWT-SBS SA-312/TP316L SA-312/TP316L: Welded,EFWT-DBS SA-312/TP316L;Welded,EFWT-SBS If you would like any more materials added just ask and we will add them right away. Piping and Flange Calculator works for both welded and threaded piping systems. The user can quickly see the selected pipe schedule and flange rating on the main input screen as well as the complete detailed calculations. It is a very useful tool for anyone involved with the Oil and Gas or Petrochemical industries (i.e. engineers, designers, plant operators, etc) Users can enter the data with sliders or using the keypad. The user is also able to use whatever units they feel most comfortable with.

Never seen a similar type of app around. ### 4/5 — Its good for a quick tool *2013-05-20* Works ok has decent range of materials, I would only use for estimate anyway not design work ### 1/5 — Pipe calculator *2013-02-14* We need calculation on pipe rolling offset, flange calculation of holes , pls review this apps **Developer response:** Thanks for your feedback. ### 2/5 — Quick calcs, accurate, limited material specs *2012-08-23* Sadly limited list of materials, no option to change Grade (stress values). ### 3/5 — Dr *2011-07-07* Neat little application but need considerable improvements. A limited number of materials are listed in this version. No help or explanation of the terms used is presented. Displays are a bit clumsy. Great potential if they consider my suggestions of improvements (sent to them via email) **Developer response:** Thanks for the feedback. We will consider your request. ### 1/5 — Not finish yet *2010-04-06* Good begining however needs lot of improvement ### 5/5 — Great app!! *2010-01-09* This app is awesome and easy to use! I paid over $30 for a shareware program which did not have nearly the same functionality. ## Frequently asked questions about Pipe and Flange Calculator ### What is the Pipe and Flange Calculator based on?
