    Vessel Skirt Design

    This takes alot of work and I would suggest a program like Compress. You will find it does a very good job for you and you can add additional loads where you wish. They have a thread going here somewhere. Regards, Allen Sindel & Associates www.consulting.awsindel.org

    I like JoeTank's answer. In particular a vessel is not a Code Vessel until the Data Report is signed which is after hydrotest. So, ASME Vessel manufactures are real particular around the end of December in order to keep there file logs and NB numbers in line. Regards, Allen Sindel &...

    Pressure equipment after fire

    Very Interesting Ideas Here :-) Here is my personal experience with ASME Code Section VIII, DIV 1 vessels that have been in "fire" damage areas both offshore and onshore: 1) First if possible get a copy of the UIA, you may need it later. 2) Identify the material via the UIA or if not, logic...

    Validity Period of PQR's

    With respect to the AWS D1.1 Code, in general the answer is no. However, the problem you can run into is if the Filler Metal designation changes in a new edition of AWS D1.1 and your PQR was qualified to a previous addition like 1996. If your contract specifies the AWS D1.1 2006 Edition then...

    AWS D1.6 1999 Qualification

    As "henri2" noted above his reference is correct. Also remember the WPS that the welder is using must either be "prequalified" or qualified under Section 3 or Section 4, respectively. Regards, Allen Sindel & Associates www.consulting.awsindel.org
