Oil and Gas Industry, UK.

Application date

April 2021.

Scope of work

Internal protection for 32/24″ pipespools in lengths varying from 1196mm to 4428mm. Pipespools would be subject to a service condition of seawater.


Corroglass 600 series. 


Copper nickel.

Coating system

  • Masked off areas not requiring coating.
