2LPP and 3LPP Custom Coating

Two- and Three-layer Polypropylene Anti-corrosion Custom Coatings

Shawcor applies different multilayer polypropylene anti-corrosion coating systems designed for the external protection of various subsea production structures. Depending on the production location, these systems can be applied onto straight lengths of pipe, field joints, bends, fabricated spools and other custom structures. They can be designed and installed in a wide range of thicknesses and configurations to meet specific performance and subsea installation requirements for both shallow and deepwater applications.

High Temperature Corrosion Protection

  • Provides excellent long-term anti-corrosion protection for field joints in subsea environments and can be used in harsh environments with operating temperatures up to 110°C (230°F)* with no depth limitations
  • The superior adhesion properties of the FBE layer result in excellent resistance to cathodic disbondment, reducing the total cost of the pipeline’s cathodic protection system

Excellent Mechanical Protection

  • The custom polypropylene coating systems are designed to provide the highest level of mechanical protection available in the industry
  • The tough outer layer of polypropylene protects against shear forces and impacts during transportation, installation and the entire service life of the subsea production structures

Engineered Solutions

  • Coatings can be applied for protecting short straight lengths of pipe and field joints
  • These coating systems can also be applied on fabricated custom parts for subsea production systems such as bends, spools, jumpers, PLETs, PLEMs, etc. Note: For temperature sensitive components such as valves please consult with your Shawcor technical advisor
  • Excellent compatibility and flexible application process
  • The two- and three-layer polypropylene coating systems applied by Shawcor are compatible with all the existing anti-corrosion polypropylene coating systems used on pipelines
  • Depending on production location, Shawcor can apply these polypropylene corrosion protection coatings by either using a spray-spray or flame spray process.*
