Seal for Life pipeline protection applied to a major oil line in India

Numaligarh Refineries Limited (NRL) is executing one of India’s premier infrastructure projects: a 1,600 km, 26-inch crude oil pipeline spanning three states. The pipeline runs from Paradip Port in the State of Odisha, passes through parts of the State of West Bengal, and terminates at Numaligarh in the State of Assam, where the refinery is located.

It also crosses several major rivers, including the Brahmaputra, Mahanadi, Subansiri, Teesta, Jaldhaka, and Ganga. Seal for Life (SFL) has provided the field joint coating protection to the entire pipeline, which is being laid in trenches, several long HDDs (up to 4 km) and micro-tunnels. There are 10 micro-tunnelling sections involved in this project, where SFL’s Dirax Fiberglass Heat Shrink Sleeve System has provided the anti-corrosion and mechanical protection on the joints, and the Powercrete-DD Fiberglass Re-enforced Abrasion-Resistant Overlay Coating has provided the required abrasion resistance to the parent 3-layer polyethylene coating. In addition, SFL’s Anodeflex has given the required cathodic protection to these micro-tunnels. A prime example of comprehensive pipeline protection using SFL’s wide range of brands.
