Sizing Tee out, to 1"bore BSP/22mm pipe run, blast cabinet + garage

[ElderWelder]

Setting up 100 ltr tank with 2" bore BSP outlet. (Was reduced to 1/2" bore BSP, removed with heat and large hammer)

Looking to tee off to blast cabinet and garage pipework, which will be 1" bore BSP plus 22mm copper & stainless (because I have lots of salvaged pipe and compresion fittings )

With a view to the future, and a larger output compressor , should I tee off at 1.1/2 bore BSP or is 1" bore BSP sufficient. Will probably tandem another 100 ltr tank to above.

While standardising with 1" bore BSP is easier/cheaper for future reconfiguring I do not want to create a restriction at the tank. Valves will be full bore.

Your thoughts appreciated.

i use 3/4 bore pipe on my blasting gear 20meter length 90 cfm at 90 psi so inch bore would be more than adequate

Thanks for your confirmation, I have 3/4 bore BSP female to 22mm compression fittings available to change from BSP to copper.
