Have you seen this kind of failure before if you do not follow the instruction below?

"All austenitic stainless steel surfaces proposed to be insulated and having temperature above 50C shall be suitably protected by wrapping with aluminium foil 0.1mm thick or painted with suitable anti-corrosive paint before application of insulation as protection against chlorides in insulating materials and stress corrosion cracking."

"Standard Specification for Thermal Insulation for Use in Contact with Austenitic Stainless Steel" with Low leachable Chlorides.
RE: About insulating stainless steel...
There are two parts to prevention. First is low choride insulation. Second is making sure that no corrosive agents can enter the insulation. If these lines are out doors then you should use epoxy coated piping. The insualtion must be covered with weather shields. And make sure that there are drain holes in the bottom side.

Can you give me popular examples for low chloride insulations?

I suggest you to look at NACE RP 0198-2004 "The control of Corrosion under thermal insulation and Fireproofing Materials -As Systems Approach", you will find all the information you need regarding this issue. Also look at http://www.hse.gov.uk/offshore/corrosion.pdf.
Hope this help
