Offshore pipeline coatings
Offshore pipeline coatings
(OP)
Hi,
my question is about pipeline coatings. In particular I would know if it is possible to put concrete coatings above thermal insulation coatings.
The main pipeline data are:
Pipeline 8"
Insulation Thickness 40 mm
Concrete coating thickness 40 mm
Thank you.

According to the same manufacturer, one of their concrete products can be applied over anti-corrosion and insulation coatings.

Are you ready to use it?

Honestly, I've never heard about this in offshore Brazil. In my opinion, the concrete coating acts as a insulation for the pipeline. So, you might wanna go back to the insulation calculation and review it.
In addition, I don't think the strength of the insulation is capable of holding the concrete coating in place during the installation of the pipeline.

Thanks for your reply.
when you need to reach high value of thermal insulation (below 4W/m2K), the concrete cannot be used as insulation so you would need to add a proper layer.
After the post of SJones I got in contact with that Company and they states that is possible to do that without major issue (in terms of applicable thicknesses).
