GB Gas Pipe Sizing Calculator

If your a total mong then you’ll struggle with this app, if you can spell your name then it’s actually a really decent app.

This app does not tell you what size pipe is required for each branch. Not eorth buying it, i regretted buying it 5 minutes later !!!

Do not bother!!! Rubbish.

This is a good little app for checking gas pipe sizing. It confirmed I had an undersized gas pipe and meter. It was easy to change the sizing and do a recheck. Results can be stored as a picture and printed out.

After paying £5 for this app I was hoping it would be more advanced then the cheaper ones . It would nice to see an app which tells you how much of each size copper pipe can be used at each section before being able to reduce down ie 5m of 28mm copper and then 10m of 22mm whilst adding bends, elbows tees etc. perhaps the ability to add appliances kw ratings as well . Thanks

Avoid u have to put all info in your self

Good app which basically does what it says, would be great to have non domestic pipe sizes added as it would really save time when on commercial gas jobs, would happily recommend.

This is only a good app if you aren't doing a u16 meter, and would be greatly improved if you could input the kw of the appliance, especially considering the price. Apart from that it's very easy to use

Would be better if you could just type what flow you need and then it tells you min pipe size

This app don't work for pipe sizes above 22 mm for the 1st run and the answers are all out by 0.3 mbars
