subsea pipeline coating

[cedric]

Hi,

I would like know if someone has experience in marine anti-corrosion coating, and what would be the practical problems encountered with some them. for instance, Coal Tar Enamel (CTE), FBE, 3XLPE, PP and PU coating? advantages/disadvantages.

Another question about thermal insulation. does anyone have data on polypropylene mechanical properties as function of temperature and pressure, as well as creep (compression) data.

Thanks.
Cedric.
