Pressure Vessel Stamp Question
Pressure Vessel Stamp Question
(OP)
I was looking at an unfired pressure vessel made in PA (USA) in 1967. The manufacturer no longer exists. The Vessel carries a "U" stamp, It also has a "W" stamp and a "CU" in a shield rather than a rectangle.
Whay are the "W" and "CU"? The Vessel also has an ASME number. Would that provide more information?
Thank you in advance

The best way to test something is to squeeze it, slowly, until it breaks!





RE: Pressure Vessel Stamp Question
ASME or the NBIC should have the Data Report on this vessel since you have a number. If someone purchased this company they also may have the Data Report.

Aside from the above mentioned marks you will sometimes find a "makers mark" along with the mark of crew that fabricated the vessel. It seems that a lot of companies were proud of their work and liked to mark it. Another area you find strange marks is where a welder stamped his weld with symbol instead of alpha-numeric characters.
