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...
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...
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...
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...
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 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.
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...
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...
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?
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...
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?
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...
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?
During inspection I came across a Made Up Sample Quill that has a Swagelok fitting inside a tapped flange.
The one swagelok piece that's threaded in the tapped flange item number is: #1210-1-12-BT

Does it state anywhere in code that 2 Gauges are required for hydro, or that one is for high point and one is for low point? Also the gauge range specifically for B31.3 or Asme Section 8? I'm looking but can't seem to find that Gauges are even required at all as per code for hydro's which...
We are building modules and one of our 16" sch 40 lines from the fab shop has the pipe shoes slightly off center. The shoe rests on the beam on one side but the other side the shoe is off the I beam about 1/8" 3mm. They said 1/8" is the tolerance but I don't see any tolerance given in any code...
