Pipelines & Anti-Corrosion

Drawing on knowledge of the difficulties experienced primarily in the water, oil and gas industries in guaranteeing durable protection for pipelines, and supported by research undertaken by some of the world’s leading oil companies, Flexcrete Technologies Limited has perfected thin film cementitious coating technology specifically designed to respond to industry demands.

This is a major advancement in coating technology, incorporating the benefits of copolymer and epoxy resin chemistry into water-based cementitious systems, suitable for application in the most demanding environments, providing tough, long-term protection of steel. These ‘stand alone’ products are applied direct to ferrous metals, chemically reacting to provide anti-corrosion protection. They cure to form a dense barrier to keep out the fuels for corrosion without the need for a special priming system. The properties achieved include ultra low permeability and diffusion resistance to oxygen and other gasses whilst creating a barrier to the ingress of chlorides.

This technology is not, however, confined to corrosion protection for steel pipelines. Given that the formulations are cement-based, a homogeneous bond is achieved to concrete surfaces, making it the ideal choice for the protection of precast concrete sections which may otherwise be susceptible to damaging corrosion of the reinforcement or pre-stressing wires.

Cemprotec E942 has significant advantages over conventional pipeline coatings, such as fusion bonded epoxies, three-layer polyolefins and liquid epoxies (including coal tar).
