Can a flanged connection be used for measuring pipelines with local pressure gauges, where the design pressure is PN260? If possible, what size should the pipe be? 12*3?

Flange connection is preferred based on experience. Theoretically, a ferrule can be used; it is best to consult a design institute.

For a pipe with an outer diameter of 12 and a wall thickness of 2 mm, the corresponding pressure is 47.5 Mpa. Such a high pressure is considered acceptable according to Swagelok’s sample manual, but it is not specified in the HGT 21581-2012 HG automation installation manual.

A bayonet-type TUBE tube can be used, 1/2"*0.069" or 1/2“*0.075‘’
