Was in the middle of pulling a tube at the Martinez refinery and my old 20-ton Porta-Power just gave up. Seal blew out, hydraulic fluid everywhere, and I had to wait 45 minutes for a replacement from the shop truck. Anyone else had a jack fail at the worst possible time?
I was crunching numbers for a 250 psi steam drum I welded up last month and realized I overestimated the wall thickness by 3/16ths of an inch. Found the stat in an old ASME code book my foreman lent me from 2019, and it said the safety factor was way higher than I thought. Turns out I could have saved about $200 in material on that one job if I’d looked it up first. Kinda funny how a random fact like that can make you feel both dumb and relieved at the same time. Anyone else ever catch themselves adding extra steel where it’s not needed based on habit?
This happened last Tuesday on a job in Gary. I was setting up a header on a boiler drum and my green apprentice grabs my old Starrett bevel gauge out of my box without asking. He tries to yank it open like a pair of pliers and the locking nut was still tight. Snap! The blade cracked right at the pivot point. I was pissed but I kept my cool. I spent the next 20 minutes using a piece of scrap shim stock and a magnetic base to get my angle the old school way. It actually worked but it took twice as long. Has anyone else had to make a field repair on a busted tool and just had to roll with it?
I was working a shutdown at a power plant near Detroit and we found this small leak in a feedwater heater tube sheet. The thing was dripping condensate right into the channel head and we had to figure out if it was a tube end failure or a sheet crack. I used a borescope to look inside and spotted a pinhole right where the tube met the sheet. We ended up expanding the tube and seal welding it on the spot. Anyone else run into tube sheet leaks that looked small but took forever to fix right?
I was on a shutdown at a steel mill near Cleveland last month helping with some boiler tube work. There was this older welder who refused to use any preheat on his joints even though the spec called for it, said he's been doing it 25 years and never had a failure. On the other hand, the inspection guys were threatening to red tag everything if he didn't follow procedure. Does tradition beat out the paperwork every time or is that just asking for trouble down the road?
We were three days into a tube replacement when a steam drum blowdown valve failed and shot 350 degree water across the deck. Nobody got hit, but it shut us down for 48 hours waiting on a new valve from a supplier two states over. Has anyone else had a minor part stop a whole job cold?
Last Thursday I was working a shutdown at a refinery in Baton Rouge and one of my rig welds on a steam drum started cracking under hydro test. I always thought my prep was good enough, but the foreman walked over and showed me how I missed a tiny bit of mill scale near the root. He swore by using a needle scaler on every inch before even striking an arc, not just a grinder and wire brush. I tried his way on the next joint and the weld laid in perfect, no porosity at all. Now I spend an extra 10 minutes on prep for any pressure vessel work because that one fix saved me a re-do that would have cost 4 hours. Any of you guys swear by needle scalers for root prep or is it just me?
I was working a shutdown at the paper mill out in Port Townsend last spring. We were doing a routine hydro test on this old Babcock and Wilcox boiler when the handhole gasket let go at around 150 psi. Water shot across the room and soaked my tools. The foreman just shook his head and said that gasket was 6 months past its shelf life. I never paid much attention to gasket dates before that. Now I check every single gasket I pull out of the box and write the install date on the outer edge with a sharpie. That one blowout cost us 4 hours of downtime waiting for a replacement. Has anyone else had a gasket fail on them because the rubber was too old?
I figured I'd save a few bucks and bought a 10-pound spool of no-name flux core wire online. Got halfway through welding a seam on a 4-inch tube sheet and the wire started birdnesting inside the gun. Spent 2 hours fighting with it before I chucked the whole spool in the trash. That cheap stuff also left slag so thick I had to chip for what felt like forever. Ended up driving to the supply house for Lincoln wire and finished the job in half the time. Anyone else get burned by bargain wire that cost you more in the end?
Had to patch a 30 year old boiler at a factory outside Detroit last Thursday. Tried using a mig welder at first cause it's faster and I was in a rush. Honestly the slag just wouldn't clean out right and I kept getting porosity. Switched over to my old Lincoln stick welder with 7018 rods and the weld laid down perfect first try. Anyone else find stick just works better on dirty old metal no matter what the new guys say?
I used to drag that oxy-fuel torch out every time I needed to cut heavy plate, and it worked fine but man it took forever. Getting a consistent preheat on 3/4 inch plate in winter was a pain, especially when the wind kicked up in the yard. Then I picked up a Hypertherm 30XP after a job in Gary where the lead man let me use his. The difference in speed is night and day, I cut the same plate in about thirty seconds now versus five minutes with the torch. It also leaves a way cleaner edge, so I spend less time grinding before welding. My only gripe is it chews through consumables faster if I push it too hard on dirty steel. Anyone else switch over and find they use their torch way less or almost never now?
Bought a 3-pack of their flame-resistant welding caps thinking they'd last longer than the cheap ones from the hardware store. First one literally fell apart at the seams after 3 days of pipe work up in a refinery. The stitching just gave out, not even a spark hit it. Anyone else had bad luck with their gear or is it just me?
Been a helper for about 18 months and finally got to lead a small tube repair on a heat exchanger at the plant outside Gary. Walked in Tuesday morning nervous, walked out Friday with zero leaks after the hydro test. Anybody else remember that first time they felt like they actually knew what they were doing?
Guy was overseeing a big tank job in Baton Rouge. Said real pros measure three times. One for the tape. One for the scribe. One for the guy holding the other end. Tried it on a recent flange layout. Saved me from a costly screw up when I caught a half inch offset. Any of you fellas do something extra like that?
We were patching a crack in a 24 inch drum at a refinery near Baton Rouge, and the heat index hit 113 that day. By hour 10 my gloves were soaked through and I couldn't feel my fingers any more. Anybody else have a job that just pushed too far?
So I'm working on this heat exchanger at a plant outside Houston, and the tube sheet had some serious corrosion around the edges. My foreman showed me this method where you use a needle gun to clean out the grooves before you lay down the new weld. Saved me about three hours of grinding by hand. Has anyone else tried this approach with stainless tube sheets?
Was on a job last week with a new guy, a kid fresh out of a 6-month program. He grabs a fresh rod out of the oven, sticks it in the stinger, and hits the arc. The first weld was a wet mess of porosity and slag inclusions. I called him out on it and he had no idea what I meant about burning the rod end to cook off moisture. Took me 15 minutes to explain that low-hydrogen rods need that 30-second pre-bake at the arc before you start your bead. Has anyone else seen young fellas skip this and then wonder why their X-rays look like Swiss cheese?
I was on a job at a steel mill outside Gary. Old firetube boiler, maybe 60s era. I was checking a manway gasket when the pressure relief popped. No warning. Scraped my arm on the lagging. My foreman said they'd bypassed the safety cutoff the night before to keep production going. I don't skip a pre-job walkthrough anymore. Anybody else run into bosses cutting corners like that on older units?
I was spending way too long chipping away at old gasket material on tube sheets. Tried a wire cup brush on an angle grinder and it shaved off 20 minutes per sheet. Anyone else ditch the torch for brushing?
I was sweating a joint on a 40-foot scaffold when the regulator started surging and nearly blew my tip off, so I swapped to the backup gauges and finished blind while the foreman chewed me out for not checking the seals beforehand - has anyone else had a regulator go bad out of nowhere like that?
I had to tell the foreman to stop because the slag inclusions were already showing up on the x-ray inspection and it would have failed the hydro test in a week, has anyone else dealt with guys cutting corners on filler metal like that?
I was on a job in Gary last month looking at a boiler from the 80s that was still holding up fine. The welds on that thing were tight and clean, but the new work I see coming through from younger guys looks more like a bird walked through birdshot than actual bead work. I think the shift to MIG over stick in a lot of shops made people lazy about heat control and puddle watching. Has anyone else noticed older rigs just outlasting this new stuff by a long shot?
I had a condenser tube leak on a job in Baton Rouge last week. Thought it was a bad weld, so I cut it out and rewelded. Leak was still there. Then I checked the tube sheet and found a hairline crack running behind the tube. Three days of chasing my tail, and it was a 2 hour repair once I found the real problem. Anyone else ever waste time on the wrong fix first?
