Pitting and corrosion may happen due to high humidity, coastal environment, body sweat, soil and dirt, left moist or wet etc. you can Identify corrosion when your firesteel surface looks like a patina or grey instead of clean silver or aluminum type.
Coat it with clear nail polish/cyanoacrylate/varnish if it's not going to be in use for more than around a week or 2-3 days if you're in harsh environment.

I am looking for a dataset to predict corrosions of oil and gas pipelines , can't find anything on the internet, please help.
My wife & I are in the process of purchasing a home, and I wanted to solicit some feedback from the sewer inspection that we got. I felt our plumber's commentary was a bit light on the insight department; they highlighted the presence of some roots at the connection of the clay to cast iron and that there was pitting/scaling on the cast iron pipes, and then a portion where the sewer is holding water. What I want to know is -- what am I looking at?
Sewer Camera Video: https://youtu.be/6hwIUQr_fJ0
My concerns/questions:
- If we're purchasing this home, can we have the cast iron descaled to remove the corrosion/pitting (1m 10s)?
- If the system breaks, is this eligible for a more affordable repair via trenchless, or are we stuck digging up the slab?
- How problematic is the presence of pooling water in the sewer line (1m 45s)?
Note: The footage is taken from a pulled toilet in the finished basement, which should be in slab...which is where my concerns arise in case we have to replace it soon.
Hey, I recently discovered what looks like bubbling on the frame on my OP7P around the sim tray and antenna line as well as next to the charging port and I think it might be pitting corrosion, I'm not sure what would have caused it because I'm really careful with my device. I've looked over the phone and it seems to be isolated to that area. Any info or help on the matter would be helpful! https://imgur.com/a/rKRSAf4
Hi Folks,
I'm an officer aboard a cargo ship currently in shipyard and I was curious about some of nomenclature being used around here. On the hull and within the ballast tanks (tanks that hold salt water to lower the ship's center of gravity and immerse the propeller/rudder) there are zinc anodes. The chief mate tells me that they are sacrificial anodes to protect against galvanic corrosion. Later, I'm told by the chief engineer that they are there to protect against electrolysis (I assume he means electrolytic corrosion). I haven't heard any of this talk since I was a 1st year cadet, and after doing some searching on google, it sounds like both could be at play.
I understand galvanic corrosion is corrosion caused by two different metals in contact with one another in the presence of an electrolyte (salt water) but I dont understand how it occurs to an immersed hull which is only in contact with the same kind of steel. I'm more confused about electrolytic corrosion. What is the dissimilar metal to the steel? The sodium in the salt water?
This seems to be inevitable on Supras due to the chrome over Aluminum shell.
Speaking to our local drum guru he said they just churned them out and it's corrodes from the inside out. At least the issue starts on the inside. He also said the problem is between the chrome and the Aluminum and moisture (even fingerprints) between the layers at manufacturing time.
Is this a problem with other chrome plated drums? ie Chrome over brass.
I understand the chrome was initially used purely for aesthetic reasons. But the shells look really crappy IMO when pitted, even if it doesn't affect the sound.
Any other thoughts or knowledge on this topic would be appreciated.
Hello all, I'm wondering if having two SS 316 plates semi-permanently bolted together (flat) on the deck could lead to pitting corrosion from lack of oxygen.
The scenario is the following: I want to permanently install some bases for stainless steel guard rails. The base would be a piece that is integrally attached to the deck and would have a flat mating surface with 4 tapped holes to be screwed into.
The guard rails would be bolted onto these. I'm wondering if the mating surface would be prone to the type of corrosion that is said to occur in less accessible areas like on keelbolts etc.
Thank you.
I've done a fair share of googling, but I can't seem to differentiate the two. Are they completely different?
I ask as I'm troubleshooting a corrosion problem at my job.
Thanks for your help.
Pitting and corrosion may happen due to high humidity, coastal environment, body sweat, soil and dirt, left moist or wet etc. you can Identify corrosion when your firesteel surface looks like a patina or grey instead of clean silver or aluminum type.
Coat it with clear nail polish/cyanoacrylate/varnish if it's not going to be in use for more than around a week or 2-3 days if you're in harsh environment.
