    Calculating Stress Ratio ASME B31.3 Figure 323.2.2A Note 6

    Welding 6" 10S Pipe 3.4mm WT 316(L), MDMT is down to -43°C. The area I struggle is how to calculate the Stress Ratio. We are warmer than or equal to -104°C. It says stress ratio as defined in para. 323.2.2(B). I don't understand Temperature Reduction in 323.2.2B. Is that plus or minus? If it's...

    Notch Toughness Requirement A312 317L Pipe

    We have A312 317 12" 40S Pipe, Design Pressure of 2750 kpa and Design temps at 420C with a MDMT of -43C. We are trying to figure out if our WPS would require impact testing. Table 323.2.2 4 States Austenitic stainless steels Note 6 (6) For austenitic stainless steels, impact testing is not...

    ASME Sec VIII Div 1 full pen weld on a mixer

    My apologies, I did a poor job at explaining things. This will require an AB-40 repair, it is a mixer in Alberta. It was a 7mm plate that is being cut 1" away from the shell, non-pressure plate. I was more referring to what NDE may be required. But I believe the work pack is correct that just a...

    ASME Sec VIII Div 1 full pen weld on a mixer

    Our company has been asked to cut out some mixer 7mm plates from inside a mixer, these are non-pressure components that are welded to the shell, we will cut the plates 1" from the shell and not touch or weld on any pressure boundary. Since we are cutting these mixer plates, when we put that back...

    16Cr-11Ni-2.5MoCb Furnace Tubes

    We will be doing some NDE LPI inspections on some Furnace tubes 16Cr-11Ni-2.5MoCb. We don't expect any repair but just in case we want to make sure we are covered with a WPS. As for code the client states Examination shall be required per ASME B31.3. With regards to the material, it looks to be...

    ER16-8-2 Electrode

    The client has asked us to use that Rod, but I will ask that question. Thank you for the feedback.

    ER16-8-2 Electrode

    Yes, high temp service is correct. Also yes this is for the client. I believe they should accept.

    ER16-8-2 Electrode

    We got asked to weld using ER16-8-2 for 310 SS for vessel work. We have a standard P8 to P8 procedure. The procedure has the standard AWS D1.6 table showing basic rods under P8 we can use for different recommended base materials. The QA said he believes we cannot use this procedure for ER16-8-2...

    PWHT Question B31.3

    Table 311.1.3 states P1 material a preheat of 200°F for thickness of >1". The table name is Exemptions to Mandatory Postweld Heat Treatment. Does that mean I must: 1. Preheat to 200°F if my material is over 1"? or 2. Preheat to 10°C for example then PWHT if my material is over 1"? Or is it...

    Welding ASTM A790-UNS S32205 (2205) to F51/F60 Fittings (2205) P-10H

    After further review and talking with the manufacturer. It appears the only issue is the cost in which that rod is much more expensive and the recommended rod as per the Manufacturer that would be ER2209. We are adding extra alloy elements that are not required.

    Welding ASTM A790-UNS S32205 (2205) to F51/F60 Fittings (2205) P-10H

    Welding ASTM Pipe A790-UNS S32205 (2205) to F51/F60 Fittings (2205) P-10H We have a WPS that is P 10H to P 10H which gives an example of UNS S32750 etc. The concern I have is the rod is an ER2594 not a regular ER2209 rod. I feel like we are using a Cr25 rod for Cr22 parent materials...

    Non-Pressure Fillet Welds vs Pressure Fillet Welds

    Thanks SnTMan! We are going to go with Pressure Boundary, or perhaps External Pressure Boundary.

    Non-Pressure Fillet Welds vs Pressure Fillet Welds

    Non-Pressure Fillet Welds vs Pressure Fillet Welds. When welding a shoe attachment directly to a pipe that contains pressure. Is this considered a Pressure Fillet Weld or a Non-Pressure Fillet Weld? Or is it considered a Pressure Fillet Attachment? Another argument is that a Socket Weld is a...

    Trim 8 Valves

    We ordered Trim 8 Valves. On the Valve handle it reads the following: Disc CR13 Stem CR13 Seat CR13.HF Our API 600 Trim Number Chart at work reads Disc 410(CR13) Stem 410(CR13) Seat St Gr6 (CoCr Alloy) The Seat does not match. Looking up API 600, although ours is a 2001 version, Table 13...

    Welding 410SS to 410SS using ERNiCr-3

    I saw a welding procedure approved for welding stainless but it is a Inconel rod welding 410SS to 410SS using ERNiCr-3. Would 410 rod not be better? Any reason why they would be using Inconel?

    Monorail welds Cracking

    I got called to look at a job where they did MT on existing stitch welds. The stitch welds are welding monorail to a structural I beam. The client asked the contractor to remove the weld then reweld new weld. I was surprised they didn't do any LPI to make sure of no cracks in parent material...

    ASME 1 Vessel

    During inspections we found that flanges off the vessel were off by 3 degrees. The manufacturer says it is fine. But we do not think so. Is there anything in ASME 1 that states clearly the tolerance or do we have to go off of b31.1.

    Vessel Inspector must be from a 3rd party agency?

    Vessel Inspector must be from a 3rd party agency? I was told that as per ASME Section VIII requires that all vessels be inspected by a qualified third-party inspector which is employed by an Authorized Inspection Agency. I was looking at ASME Section VIII Div 1 and I can't seem to find where...

    ASME Section VIII Div 1 RT Porosity Question

    When looking at RT film for Carbon Steel (UCS) on a vessel weld when pertaining to porosity. Is the acceptance criteria for porosity size under Appendix 4 4-3 Acceptance Criteria? If yes, then why is Table 4-1 labeled as an example chart only? Am I looking at the wrong area?
