Pipe Coatings

Corus provides pipe coating services from BSR Pipeline Services Limited; a joint venture company with Ramco Pipeline Services Ltd.

The range of coatings includes internal liquid epoxy and external FBE and 3 layer PE & PP up to 48' diameter. Subcontracted concrete coating can also be arranged, along with field joint coating if required.

Fusion bonded epoxy coatings

Fusion bonded epoxy coatings have a considerable track record for the anti-corrosion protection of pipes both offshore and onshore. Benefits of this particular coating include:

high productivity rate enabling quicker availability of coated pipe on site.
Protection over a wide temperature range.
Ability to be stored in all climatic conditions.
Long-term adhesion to steel.
Resistance to soil stress and backfill compaction.
High resistance to cathodic disbondment.
Flexible enough to accommodate field pipe bending.

Three layer polyolefin coatings

These systems consist of a powder epoxy primer layer, polymer adhesive layer with an outer layer of polyethylene or polypropylene. Three layer systems offer a number of advantages over fusion bonded epoxy coatings: -

Stronger resistance to damage during transit, storage and laying.
Protection for pipelines at higher operating temperatures; 80°C for Polyethylene; 110°C for Polypropylene.
Suitable for use under concrete weight coatings without further treatment.
Better suited to reel ship-laying methods.

Internal coating

Internal coatings are utilised by both the on and offshore industries to minimise internal corrosion of linepipe systems and to increase flow rates.
