Borcoat for Steel Pipes

 

 

Borcoat PE & PP systems against corrosion of steel pipes

 

Steel pipelines are used for transport of natural gas, crude oil, petrochemicals and water at high pressure over long distances. These high value pipelines need to be guarded against corrosion by external coating systems and cathodic protection.

 

Most strongly dominant worldwide are the three components PE coating system, the three components PP and multi component PP system, which are more recognized as the excellent systems for onshore and offshore projects. This is due to inherent advantages over other materials:

 

Provides the best mechanical protection – Protects the pipe from damage during handling, transportation and installation.

 

Wide service temperature range: 0OC to + 140OC for 3LPP coating. -45OC to +90OC for 3LPE coating.

 

Highest durability – Very high Environmental Stress Crack Resistance (ESCR) to resist cracking against environmental forces and moisture, chemicals in soil and other oxidative elements.

 

Resistance to heat and light – Fully compounded materials are stabilized against thermal and UV ageing for high service life.

 

Easy to apply – Through side extrusion, crosshead extrusion or powder coating techniques. Successful twenty-five years track record – the 3LPO coating system is now the leading corrosion protection system for oil and gas pipelines in the world.

 

Wide product range – PE and PP top coat and adhesive are available in granule and powder form, weight coating, insulating foam, injection moulded and machine applied field joints, HDPE pipes for pipe-in-pipe insulated systems.

 

Best whole life cost vs coal tar, asphalt and Fusion Bonded Epoxy (FBE) – In terms of service life, mechanical and moisture protection, 3LPO coatings will yield the least number of repairs and saving in cathodic protection.

 

Newer challenges in deep sea and offshore projects – 3LPO coatings are best equipped to face the newer challenges in terms of tougher environment, higher temperatures and longer service life.

 

Continuous developments – Due to continuous research and development in catalyst and reactor technologies, there is a step change in material properties every 5-10 years.
