Thanks @mk3223.
With an LTCS gasket in place and process liquid getting to the flange connection of the SS injection line and LTCS process line, will the gasket not get pitted over time thereby leading to leaks?
Hello guys.
I have a Topsides chemical injection assembly (top injection orientation) which is supposed to come into a main flow line. The chemical injection line and the quill are made of 316L while the main line is LTCS.
My question is what sort of gasket needs to be placed between the...
Thank you for the responses Chumpes,GarryB1957 and cap1a79.
My question is mainly regarding connection of dissimilar materials from galvanic corrosion point of view. Not CP related.
For example, if I have a conductive fluid passing through a titanium line outlet connected to a carbon steel...
Thanks @engg1405.
I concur with what you said regarding the isolation kit but the isolation spool explanation doesn't seem to be true because you will usually have a pipeline polyurethane wrap for the soil to air interface of pipeline to avoid soil corrosion. Have not seen where a spool within...
Hi guys. Can someone help with this please?
Is there a rule or standard that differentiates when to use insulation kit as compared to isolation spool or vice versa?
How do you determine which one to go for during design of piping material to avoid galvanic corrosion of dissimilar materials if...
@XL83NL. Sorry I just edited the initial post rather than reply.
Yes. Looks overkill as you mentioned. Vendor has some of the material left in stock and asked if they could use it else why I asked the question. Wanted to be sure there isn't something I have overlooked which could cause...
Hello. Can someone advise whether Inconel 800 material is suitable for seal gas electric heater element fabrication please?
Max Operating temperature will be 45degC.
Heating element is to be used in heating up the seal gas (routed process gas) which in turn is used to prevent leakage of...
Thanks once again @LittleInch.
The size of the 2 risers is 8inches. Not sure how much is below the sea to be honest but total length of risers to sub-cellar is approx 60metres.
The other point that is of confusion is both of them are same size, filled with same freshwater and in the same...
Thanks for the response @LittleInch.
M understanding from person on board is that there hasn't been much of a temperature variation over last week.
The risers are still filled with freshwater left in there after hydrotest as they couldn't discharge into sea since an equilibrium pressure will...
Hi guys. Need a bit of assistance on explanation for this. I am looking into the internal integrity preservation of future risers for a client.
The future risers were installed about 6-7 years and were pressure tested in-situ using freshwater to 230 barg. Documents at my disposal says that the...
