    Hydro test and safety of workers?

    Our safety man is having an issue with a contractor on site who wants to work in the area where vessel hydrostatic testing is taking place. Years ago in some documents or code it said that only personal taking part with the hydrostatic test shall be in the area. I said this and the contractor...

    ASME 16.5 question?

    Thanks, we do have an ASME B16.5 2003, but the firm that built this in 1996 stated the 1981 edition I guess.

    bursting discs

    I use bursting discs, but here is a pet peeve of mine. Most of the time when you are using an EPC for a new system they give the job for ordering the discs to the new engineer. He/she uses the data on the U1-A form and orders the bursting discs to the maximum allowable working pressure and...

    Shop certification for CSA B51

    I think you are asking if power piping or pressure piping needs to be registered; all pressure equipment built in Canada needs to follow Provincial rules, CSA- B51 and ASME codes. Piping it self does not have a CRN number, but CSA B51 4.17.2 states: “Where required by the regulatory authority in...

    Fired heater tube fretting.

    Just to fill in some of the blanks, the heaters has a water/glycol (heat medium) mixture in it; the temperature of the heat medium on exit is 290 F. All of the tubes show wear from contact with the guides. The heaters have just been inspected and the tubes for now are safe but the deepest...

    Amperage check on a welding machine.

    How is an amperage check on a welding machine done (SMAW)? I clamped an amp meter on the lead and the amp meter showed lower than the set reading on the welding machine. This welder did have a remote but I thought that clamping it near the machine would be more accurate. This did cause some...
