The Routine Repair rules affect the involvement of the Inspector, and the requirement to attach a repair nameplate. The pressure test requirements are the same for all repairs, routine or non routine. PVinspector

The key, as I think metengr referenced, you can pass the test with 100%, but if you are not working for an AIA, jurisdiction, or third-party agency recognized by the National Board, you cannot get a commission. There is no such think as an independent or freelance AI, like with an AWS Certified...

Thanks for all the responses, I think I understand the process now. I have seen replacement boiler coils sent out with no AI witness, but the P-4 states "hydrotest witnessed by XXXXXXXX (certificate holder's) authorized personnel only, so I guess in the field they must hydrotest it as part of a...

Where in ASME Section I does it allow the S stamp holder to hydrotest coils without the Authorized Inspector witnessing? Thanks.

If the vessel is new, and has not been in service, when you send it back to the Certificate holder who built it they often check to see if the data report has been submitted to the National Board. If it has, R stamp should be the only option. If the Data Report has not been submitted, and the AI...

The question was: Is it allowed? (assuming here for VIII Div.1) The answer to that question is: Yes. Other comments are related to whether it is a good idea or not. IF UCS-6 of Section VIII-1 had restrictions on plate for pressure. What is not prohibited is allowed.

using common sense I believe it is mandatory. Never apply common sense to Codes or Standards, it will get you in trouble. EN 10204 is about the type of inspection document supplied. No where does it say to put "EN 10204" on anything. Doesn't say it, it is not required. Makes sense for every...

Repairs and alterations are done by R stamp holders, as trottiey mentioned. Go to this website: http://www.nationalboard.org/ManufacturerDirectory.aspx Type in your jurisdiction (state or province) and R for the stamp and you will get a list of R certificate holders. Adding a fitting like an...

The National Board's website certificate holder search also shows ASME stampholders, even though NB does not issue them. You can search by specific stamp, or all stamps. http://www.nationalboard.org/ManufacturerDirectory.aspx

If you are a job shop or custom contractor, it is very hard to beat the databases of material, instant checking of impact test exemptions, etc., that good commercial software have. We seem to have some engineering egos here who don't want to admit it. Also for vacuum tanks, heat exchangers, etc...

Thread-O-Lets are not banned in Section VIII, but there is no figure in UW-16 that is like a TOL. Also, with the groove built in to the TOL producing a fillet leg is not practical. Use a coupling, and save the TOL for B31.1 work. The calculations for proving out the weld strength are shown in...

Who has ever accurately calculated the MAWP for a dimpled jacket?

Regrumble, Thanks for the correction. I knew about CRN numbers, but thought they were required in addition to the National Board number. That is helpful.

Most US Jurisdictions (states and large cities), and all Canadian provinces, require pressure vessels installed in their areas to be registered with the National Board. It allows for an easy and permanent method to get a copy of the data report for repairs and alterations once installed, and to...

Rneill, Where did that 35% of MAWP for "pressurization" come from? Just curious, I have never heard of a value for that concept.

It has been mentioned by people on the ASME Code committees who work for Hartford Steam Boiler, that Section VIII-1 will likely become a bit more like VIII-2, maybe not in the next several years. The Code moves slowly. This would mean more emphasis on UG-22 loadings, and ultimately a Users...

ArcelorMittal Burns Harbor plant holds a Certificate of Conformance from ABS Group Ltd. assuring compliance with PED 97/23/EC 7/2, Annex 1, Paragraph 4.3 for steel slabs, plate, coils, etc. - good through June 21, 2010. You can download it from their website. This is better than simple ISO 9001...

Does this apply to pipe caps? No. For Section VIII Div. 1 fabrication, pipe caps may be received and accepted under UG-11 rules for standard pressure parts. They are a built to an ASME B16.9 standard accepted by Section VIII. Also, pipe caps are not elliptical heads, and the calculations for...

ColonelSanders83, After re-reading the posts and the Scope and Fig. 100.1.2 of B31.1 I think I was too quick and did not pay enough attention to the nonboiler part. I think you are correct for NBEP that stamping and a Code Certificate is not mandatory. The best (and final) solution really is to...
