Dear All
Can anyone share information on selection and field experience of soft iron gaskets in subsea pipelines in wet crude/gas, gas lift and treated seawater injection services.

Need a bit more information. Any CO2?

Yes, CO2 in the range of 4-5 mol% and H2S is in the range of 0.3-0.35.

Section 9.2.2.2 indicating that crevices formed by bolt and bolt hole are also covered adequately.
RE: Soft Iron Gasket
It's not something I would do and for the incredibly small cost difference why are you taking the risk?

I can't imagine that, and the pH of that water will be low with that much CO2.

Are you sure? Something doesn't sound right there

The wet crude is having water content during mid to tail end life.
RE: Soft Iron Gasket
Don't worry about mid and tail life, the iron won't last that long.

Personally, my choice will be Alloy 625 gaskets with Alloy 625 WOL in gasket grooves in view of the subsea service. I am trying to look for examples of successful field experience with soft iron gaskets.
