I keep seeing the 30% strength of a WNF reference to B31.3 - can someone give the full reference from B31.3? Fitters are trying to argue that "we have slip ons all over the place without any issues" doesn't necessarily mean its best practice.

Is there a solid way to determine if a vessel is out of service?
There is politicking in management right now as a vessel went over its 10-year internal interval by 34 days and maybe we could consider it out of service for stints like during two, 20-day TARs so we'd "gain" 40 days thus still...
Chemical plant specifically... I definitely noticed both of these companies are pulling specs from the same place, BP just actually cared and did it right from what I see.
The 30 specs that are supposed to be the current use are probably worse just because it looked like we purchased the...
Inch, hopefully this makes more sense -
-6 owners since 1965.
-300+ pipe specs totalling across those owners.
-103 of those 300 are actually listed on our P&IDs. (some still call for asbestos gaskets and square head bolting!!)
-current owner brought ~30 (part of the 300 summation).
What I...
I feel you would be amazed at the disconnect from corporate to process within this company. Currently, ANY expense must be approved by a global board located in EU. I had a shop visit for a vessel build and was declined $40 for lunch between my coworker and I. The worst I've heard was in...
Has anyone been tasked with developing pipe specifications before? I've been asked to implement pipe specifications for our site maintenance and project teams to use. The origin of the request is that there are currently 103 pipe specs that are scattered throughout our P&IDs. This came from...
There was a change in the July, 1 2023 release regarding Miscellaneous Requirements. T-451 "Coarse Grain Materials" is attached, but has been described by our NDE provider as all customers will be required to buy all weld mock-ups for any new and existing weld approvals. This will either cost...
I'm still very new to FEMI but there are some great resources that have helped me:
https://inspectioneering.com/ - Your company may already have a corporate subscription, but there is also a bountiful amount of free information here.
https://www.corrosionpedia.com/ - Also good information but...
Nice! Having a skimmer would make it a more "hands free" operation where I can get out with a raking tool and push it to the skimmer. Right now I'm looking at something like this that I can mount to a truck or trailer and throw the algae in a small tank, open grain wagon or manure spreader and...
keeping it simple, we use solid manure and blend it in dry or damp. The ponds are shallow and used daily so I didn't exactly want to deplete them but I don't think i'd affect the levels with a poop tanker now that i'm thinking about it. We're just under 30 acres so we don't own a tanker and...
Thats odd... I was planning to use it for our small farm. We have some ponds in the area that we like to keep clean but it can be intense and laborious to get out physically. We plan to dry the algae or store it wet then put it on fields blended with manure.
Any chance you can share your...
I'm wondering if I can get some advice regarding pump sizing and style to remove an algae/water mixture from ponds/lakes.
Is there a pump style that I'd be able to transport on a trailer that can handle sucking up stringy solids like duckweed/algae and even sticks and be okay?
I was...
Thats where my investigation is alluding to. We changed from brine or propylene glycol to a methanol/ ethylene glycol mixture. That was ~20 years ago which still seems way too long.
We're having the system tested now to verify we're on spec. Any new fabrication is coated or painted, we're just running into 60+ year old equipment and pipe that gives us trouble. unfortunately, the leak is under a welded pipe shoe on the main return header so isolation isn't possible and...
Currently, we are evaluating a historic system in the plant due to changes in degradation rates and evidence we're seeing.
Knowledge as of today:
1. Our coolant is 74% Water, 20% Methanol, and 6% Ethylene Glycol.
2. The system is made of A53 Gr. B and A106 Gr. B carbon steel piping.
3...
I think what we may end up doing is replacing the line. Rerouting is a little undesirable because of the prefabbed carbon steel spools but I'm thinking if we hydro and get something to yank it out of there we can probably get a new pipe put in without getting too terribly wet. I don't know if...
I figured my options were few. I had thought that finding the end of the pipe and throwing a cap on was a decent plan but received a heavy glaze when I mentioned it. I get no one wants to get into an industrial run off pond but how is freezing a 15 year old PVC line any better? Draining the...
