Ins and Outs of Pipeline Coatings

Coated pipeline ready for installation

The global pipeline coatings and application services market is  worth some $5.5 billion a year, according to Noru Tsali at Ami Consulting.  Current market conditions are stormy, owing to low oil prices which depress demand for new pipelines, terrorist action in Libya, Nigeria and Iraq, financial scandals in Brazil and political opposition to new pipelines  in North America says Tsali. Factors such as these,  affect the rate of pipeline construction and repair requirements, upon which demand for  pipeline coatings are inextricably linked.


Steel pipelines are ubiquitous, both on and off-shore, dedicated to transporting   either natural gas, crude oil,   or petrochemical and petroleum products at high pressures over long distances. Such pipelines are protected against corrosion by both external and internal coating systems.


Internal coating liners are applied prior to installation of virgin pipes  or for repairs  and replacement pipes.  According to Kevin Cato, Manager IntraCoat Pipeline Services, “such linings, depending on conditions, can be applied to 15 to 20 miles of pipeline over two to three weeks.” The conditions in which pipes are laid can vary enormously,  but a common variant is temperature, which  can vary from icy cold to extreme heat. For example, Malaysian state-owned Petronas used Dubai- based specialist firm   Anti Corrosion Protective Systems, to design and  install anti-corrosion linings for its fields in the South China, where temperatures reach 120 degree centigrade.
