Hi, Hoping someone can help with this seemingly simple question, because NBIC is somewhat vague on the topic. We are looking to increase the Maximum Steaming Capacity on an existing boiler. There will be no physical changes made to the unit, and the existing PSV's have been confirmed to be...

Hi, I'm looking for some help with code interpretation. We are working on some HRSG piping and have a client who requires "flanged" thermowells. The thermowell manufacturer would be making two welds connecting the TW to the flange (J groove weld one side, single bevel with fillet cap on the...

We've got zero corrosion allowance.

Haha, yeah that's what I figured and what I was afraid of. I thought about trying to order it as min. wall pipe like you said but it's an availability issue. To check the actual thickness, we thought of taking UT readings at the 0, 90, 180, 270 position, and every 2 feet or so down the length...

Hello, Question: We're designing an ASME Section I boiler component (replacement part for existing unit), and one of the drain pipes has a calculated min wall of 0.811". It's ASME SA335 P91 Type 2 we need, and the only pipe we can find in stock is 6 inch Sch XXS (0.864" nominal thickness). With...

Hi, My company is managing some repair work to a boiler in Spain, which was not ASME stamped and registered with the National Board. All of the various ASME pressure parts were stamped by their respective manufacturers originally, and the repair work is being performed by a company holding an R...

Thanks again everyone for your opinions and advice. @weldstan, I would call it coarse martensite with coarse precipitates. The weld metal was also tested, with good hardness of greater than 200BHN at all locations. It's another point that oddly doesn't make much sense to me. ~300 tube welds...

Thanks for the advice guys. @Pradip, there were other areas tested on the assembly, and similar results. But, there arent any trends. There are even cases where one side of the weld is good and the other is not. We’ve considered removing a tube for lab testing, but are hoping we can resolve...

Hi guys, I'd like to get some experience-based feedback on a problem we've run into. We're building heat transfer modules for a HRSG project that has P91 headers and fin tubes. We've checked hardness after PWHT on the base materials and welds, but have come up with many low readings (some as low...

Hi, I have a general code question that has always confused me. When establishing the effective ASME Code for a new construction project, we have typically used the latest "mandatory" edition at the time we sign the contract. For example, a Section I boiler contract is signed Jan 2, 2018, so we...

Hi, We have a pair of ASME Section I drums being manufactured by a sub-contractor, whose workers have gone on strike indefinitely. The drums are in the middle of fabrication, and we are considering moving them to a new sub-contractor. Both sub-contractors are ASME Stamp Holders. The drums have...

I still think your only option will be to have the "part" manufacturer stamp and provide a partial data, but you may want to see if Section VIII, Div I, UG-116(h)(2) fits your situation. If the WOL Pipes are 5 in OD or under, the code stamping is not mandatory. You may be able to have your...

Did you procure the pipe from an ASME certificate holder, and did you ask for it to be manufactured according to the appropriate ASME codes including part stamps, data reports, etc.? The only parties that can certify the manufactured part and produce a manufacturer's partial data report are the...

Hi, I am trying to perform registration of an ASME Section I boiler with associated piping in Alberta, Canada. My question pertains to the CRN application process and rules for ASME Data Report forms associated with that. We have applied for two CRN numbers with ABSA, one which covers the...

Hi, I'm looking for anyone familiar with using SA 302C plate material for drums or pressure vessels. Are their any procedure recommendations for rolling or forming this material for drum shells and heads? I realize code requires this material to be PWHT when welded, but I am more interested in...

It is possible to design, manufacture, erect and test the boiler in accordance with ASME B&PV without physically stamping the boiler. When ASME is not mandatory per the local jurisdiction, you need to come to an agreement with your client on the extent to which you will meet it. You could choose...

JAYDEE23, Your customer is correct. Section I, PG-112.2.6 says P-4A Forms are to be used for shop or field-welded boiler external piping. The words "Boiler External Piping" were added to that paragraph in the 2006 Addenda of the code. Prior to the 2006 Addenda, P-4A's could be used for both...

jeevesme, 1. The NB number is issued by the Manufacturer or Engineering Contractor that stamped the vessel. 2. The NB number is a sequencial number based on that particular certificate holder's certificate number. If Company A with Certificate number 123 provides a vessel with NB# 23, that...

Great, thanks! The P-3 was the one I needed and I found it at the link you provided.

I need to fill out an ASME Data Report that I have never had to use before, and was wondering if anyone knows where I can find an excel or word version of ASME Data Forms (particularly a P-3). So far I've only been able to find pdf versions of the forms. I could always create one myself, but it...
