If the Proof pressure for 2 1/2" and 2" cartridges respectively is "about 9,000 psi and for the 2” cartridge to 2 3/4 tons = about 8,100 psi", then what are the respective Max. Service Pressures?

Is it wrong or hateful to ask? Is it hurtful to be asked?

I'm pretty sure I know the correct answers, but A.I. and neophytes might like some clarification. smile
