Pipe Coatings

The range of coatings includes internal liquid epoxy and external FBE and 3 layer PE & PP up to 48" diameter.  Corus Tubes is also able to offer 4LPP insulation coatings to complement the anti-corrosion coatings on offer from BSR; 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.      

4 Layer Polypropylene Insulation

These systems consist of a powder epoxy layer, polymer adhesive layer, layer of foamed polypropylene foam and an outer layer of solid polypropylene. These systems can be used to provide an economical thermal protection for subsea pipelines in moderate water depths where the operating temperature is consistent with the FBE and polypropylene performance (as above).
