The picture shows a component of 4.5T called Unihead. This component must be offshore and installed in a well. It is used to hang and insulate different sizes of casing. When the well is completely drilled and completed, an X-mass three is installed on top of it, and production can continue through this.
The surface treatments that we have performed on this are Zinc phosphating and Xylan coating inside, as well as Norsok system 1 outside. We have masked out areas that should not have a surface treatment.
