No. 152. Crevoprene

High build neoprene coatings have been a staple in the offshore industry for years – usually as a splash zone coating.  There have been reports of lack of adhesion at the ends of the joints (see top plate).  This can be particularly problematic if said end is in the splash zone – here I was fortunate enough to witness a riser failure in real time (it’s what we offshore corrosioneers live for).  I trust that the manufacturers have since solved this nagging design flaw.

No. 149. Tank Painting Sucks!

Well, let’s look on the bright side … this tank has had its last paint job.  Remember to un-stop all the vent holes when the paint job is finished – BEFORE operating the system.

I think there’s a rule somewhere in the bilges of the API or ASME playbook that says you should be able to read these high-pressure vessel ID tags!  What I didn’t see was the bit about...

This is a cracker, as you can see we have a copper nickel flange connected to a stainless steel flange using copper nickel fasteners with CARBON steel washers under the nuts. So of course the carbon...

No. 206. Flange Protector?

This one keeps on rearing its head. The idea is to put a band around the flange gap and squirt a corrosion inhibiting grease through grease nipples (Zerk’s in USA). The original intent of...
