Size guidance
22mm Flexigas CSST gas pipe: quick answers
Flexigas 22mm is a standard CSST gas pipe size for fixed UK gas pipework. It is commonly searched as 22mm flexible gas pipe, but final suitability depends on sizing calculations and the installation route.
DN22 sits within the BS 6891 domestic pipework sizing range noted for Flexigas DN15-DN32.
Can 22mm Flexigas be selected by pipe size alone?
No. Pipe size is only one part of the design. The route, equivalent length, connected load, gas family and allowable pressure drop all matter.
Where should I go next for 22mm sizing?
Use the Flexigas gas pipe sizing calculator and installation manual, then speak to the technical team if the route is unusual or close to a limit.
Use Flexigas tubing and fittings as a system. Do not mix Flexigas CSST or fittings with other manufacturers' CSST systems.
