Using Thermal Spray Aluminium on Subsea Duplex Pipe?
Using Thermal Spray Aluminium on Subsea Duplex Pipe?
(OP)
Guys
Working on a project which involves SUBSEA structures with duplex stainless steel (probably API 5LC LC65-2205) cooling loops within them. Inlet temperature is about 100 Celsius, although some "headroom" might be advisable.
Need to spec. amn anti-corrosion coating for the loops (which will be 150 to 200 metres long welded-up 5-inch nominal diameter pipe coils).
Client suggested gold plating them!!!
I was thinking thermal-sprayed aluminium with an organic sealer applied over the completed spool (including welds) in one fell swoop.Any suggestions / tips / comments?
Specified coating must meet DNV-RP-F112 HISC-prevention criteria.Many thanksDarren
