AISI 316 ok for Subsea Hose Clamp?
AISI 316 ok for Subsea Hose Clamp?
(OP)
Hi,
I want to use a standard hose clamp (attached example) for a subsea application. (Permanent installation, about 20 years life time).
Problem is, the only corrosion resistant steel I can find for hose clamps is AISI 316. I would prefer to use a higher quality steel, like 6Mo, AL-6XN or 254SMO, to avoid the issue with crevise corrosion.
Have anybody found this before? Or will perhaps 316 be ok? Obviously a hose clamp can take some crevise corrosion before it is destroyed. It only need to seal very low pressure (about 1 psi). Max temp is about 20-30deg Celsius, and water depth 20m.
All help is highly appreciated!

the life of SS in that condition will be short, not 20 ys for sure..
for a seawater exposure you need higher alloyed steel like 254SMO or SuperDuplex type SAF 2507 with higher PRE pitting resistnace equivalent.

Anybody knows about hose clamps made in these kinds of steels / titanium / CuNi or other materials suited for subsea applications? I have googled a lot but can only find worm-gear titanium hose clamps. I need a a T-bolt type...
Or could an option be anodic protection of a carbon steel hose clamp?
