This app is for domestic gas pipe gas sizing to the new BS 6189 2015 Standard up to 35mm copper and 11/4" Steel.
With the app you just need to enter lengths and quantities of materials such as elbows, bends and tees. This is explained in detail in the guide which you have access to at all times throughout the app, without losing any data you have entered.
There are ten preset systems for you to choose from with 1 to 5 appliances connected.
All of the pressure losses are taken from the tables in the British Standard. Also if you have made a mistake during the input stage for the sections you have the opportunity to EDIT these in an edit screen for your system.
The systems are held on a database so you can go back and edit jobs at a later stage. You can also check existing installations when you are doing your gas safety checks.
The app also enable you to print to hard copy on a wi-fi enabled printer.
Any future updates are free once you purchase the app
