We have a large vessel that the engineer wants cleaned and shipped with 5 PSI nitrogen. Does anyone know of a procedure to purge and fill the vessel so that we can guarantee it contains nothing but pure nitrogen.
The code now allows for UT inspection instead of RT under UW 51 (4) . If I am building a vessel and the extent of examination is outlined as UW 52 for spot RT can i substitute spot UT?
We are fabricating a big stack to ASME STS code and the client wants spot RT on all Longitudinal and Circumferential welds as well as the Girth welds. A girth weld and a circumferential weld are the same thing?
We received drawings with PJP-FS in the weld tail of a 1 1/2" plate "T" joint. When I called the engineer he indicated that he wanted a partial joint penetration full strength weld. I wanted to know what size bevel and fillet combination would achieve full strength and he indicated that I should...
We have a north American customer that wants us to make pressure vessels that are CE certified not ASME certified. Are there European manufacturers out there that are familiar with this. Is there anyone in North America that does this?
We are welding 3/8" 516-70 plate using lincoln L61/860 wire/flux combination and it must pass impacts at -35F. The testing results we are getting are borderline at best and I was wondering if anyone had any tips to improve impact results on such thin material. Bevel prep speed etc. Is there any...
The 2011 adenda has changed the U1A form. Does anyone know if there is an interactive version of this on the web. I tried the ASME site and can only find a PDF and I hate filling in these forms by hand.
we have a section of 40" dia 1/2" wall pipe 20 ft lg fabricated from SA516-65 that the code specified was to be normalized. Our engineer wanted it heated to 1550F. The pipe is now egg shape and distorted so it looks like we are going to built it agian. Is anyone familiar with this process and is...
I am supposed to write a document control procedure acceptable to ASME and ISO for the control of electronic drawings and specs. Does anyone have a procedure that has been reviewed and accepted.
I work for certified shop that does not currently have a code vessel in production so we need to build a demonstartion vessel for our code review. I know all the calculations and everything needs to be done up to the point of the code review but when the review is over do we need to complete...
There is an article in section IX that indicates a PQR that has already been aproved with bend and tensile tests does not require these tests to be done again if you are only adding Impacts. I do not seem to be able to find the section. Anybody know what the number is.
Our buisness is looking for a good software package that will keep track of inventory, estimating, engineering etc that is also ASME compliant for MTR's, NDT, Welder reports etc. We have alreday looked at most of the commercial programs and cannot find one the suits a plate shop doing vessels...
Does anyone have a source for the proper proceduer to calibrate a UT machine useing a Rompas block. I have searched everywhere and cannot find a reference for this.
We are fabricating vessels of 516-70 (P1 G2) with various thicknesses from 5/16 to 1" thick. The customer wants all procedures impact tested at -45C. Since impact values are directly connected to heat imput any change of the electrical characteristics changes the impact value of the test. These...
I hope this is not off topic but who better to ask about which program works except the people that use it. I am looking for ERP software that will include tracking pressure vessels in our shop. I will need to include tracking heat numbers, welders numbers, NDE reports,and all of the other...
We are fabricating a vessel from 1 1/4" SA516-70 and our Sub arc proceure uses a Lincoln EM12K electrode which our customer claims is not suitable for PWHT. They did not give a reason. Does anyone know why this electrode is not suitable or which type of sub arc wire would be more suitable. The...
We are building a clad pressure vessel and the customer wants us to do a copper sulfate test where the clad surface has been removed for weld prep to check for clean base metal. Does anyone have a procedure or information on the procees to do this.
we have a client that insists we must have a level 1 welding supervisor on staff for a large project we are quoting. I am familiar with all of the CWB codes most of the ASME codes, the ASNCT code etc. Does anyone know what code certifies a level 1 welding supervisor.
I am working on a welding procedure where the customer specifies impact values of .38 mm of linear expansion in compliance with ASME B31.3 code instead of the standard ftlbs. All of my proceduers indicate ftlbs. Does anyone know of a chart that compares ftlbs to linear expansion....
