Gas Pipe Sizing Calculator

Gas Pipe Sizing Calculator


A study carried out by Worcester Bosch Group's technical support team found that the most common cause of a boiler installation problem was from incorrectly sized gas pipes. When fitting a new boiler, often the existing pipes should be replace for larger ones due to the increased output. Smaller pipes will mean the boiler is running at a lower power and can cause an increase in carbon monoxide levels.

The Gas Pipe Sizing Calculator is an extremely easy to use app that will help you to select the right size pipes for installations using copper (up to 108mm), steel (up to 300mm) and PE (up to 315mm) pipes of sections up to 250m (820ft) in length.

To carry out a calculation simply select the gas type, enter the appliance heat input, enter the pipe length, the number of high or low loss fittings (guidance is given in the app), select the type of pipe and then press the 'Calculate' button.

The results will show the total equivalent length, the minimum pipe diameter (metric) that should be used and the pressure drop for that section of pipe.

For multiple appliances each section should be calculated in turn and the kW inputs for the appliances in each section added together for each calculation.

The maximum pressure drop from each appliance to the meter should be no more than 1 mbar for natural gas or 2.5 mbar for butane or propane. Adding all drops together using the minimum pipe diameters may cause this to be exceeded. Where possible, the results will also calculate the drop if the next larger size pipe diameter is selected on a section, this should help to ensure the right sizes are used throughout the whole circuit.

Please note: This app is designed mainly for the UK so supports metric pipe sizes only.

This is our biggest update yet!

Here's what we've added:

• Support for pipe section lengths up to 250 meters
• Copper pipe up to 108 mm
• Steel up to 300 mm
• Polyethylene up to 315 mm
• Support for Butane and Propane gases

Robinson Great app. When dun with the bigger pipe sizes

Good but... It is good but you can only calculate a run with one size pipe in it. It would be better if you could do a run that started in 22mm and ended in 15mm then calculate it. Please add this as it would make it 5 stars

It's ok It's ok but does not tell you the amount of volume in the pipe. Be good to know when your close to limits . . .

Just tried this app once so far, it would be better if the app automatically translated metric to ase all throughout the calculation so I wouldn't have to make the transition myself at the end.
