    Hydrotest Exceeds ASTM Pressure for Flanges

    Hey guys, thank you for all this information! This is super helpful! SNORGY, I'll take a look at the calibration info - that's good to know, thanks! LittleInch, What should I look at that might be weaker than my flanges? Would it be the threaded fittings? How would I determine the max test...

    Hydrotest Exceeds ASTM Pressure for Flanges

    Hey LittleInch! Thanks for your response! To answer your questions, I'm doing an engineering evaluation for a client... So I'm not sure what the repercussions of this will be on their end, but I would love to find them an acceptable solution to justify not scrapping them. Yes, the flanges...

    Hydrotest Exceeds ASTM Pressure for Flanges

    Hi all! I am reviewing some hydrotest data to confirm that the tests were acceptable and to sign off on the design. My concern is that the 600# flanges were tested to a max pressure of about 2300 psig in some instances, whereas the ASTM guidelines identify the max test pressure to be 2225 psig...
