Plant protection- Case studies

Protection of concrete and outdoor equipment in saline environments

■ Full protection to pipe support (including steel structures). ■ Adopted as a measure that allows long-term protection. ■ Measures against salt damage on steel structures will also be implemented. ■ All of this work was done by a single contractor.

Life span extension of a chlorine gas

■ Adopted after the good results of the test piece in a high temperature and high corrosion environment. ■ Operating temperature of this pipe is 200°C, and since it has a chlorine gas, a coating material with excellent heat resistance and chemical resistance is required. ■ Features of Corrothane XT ・ According to product specifications, it has a heat resistance of 160℃ in a liquid environment and 260℃ in gas environment. ・ It can be used at full pH (pH 0-14). ・ It has been widely adopted as a countermeasure in high temperature and high corrosion environments. ■ Coating measures were established in a highly corroded environment. ■ Measures by coating in a highly corroded environment have become standard.

230℃ Sludge combustion gas line corrosion protection

■ The use of special metals for corrosion also presents thinning of walls and holes due to the advance of corrosion. ■ Corrosion progresses throughout the plant due to exhaust gases containing filtered sulfur. ■ The Corrocoat products used in this application have shown great efficiency in saving maintenance costs.

Drainage pump station, lifespan extension of rainwater discharge pipes

■ Pipes that have been repaired by other companies in the past but without success opt for corrocoat products. ■ In repairs done by other companies (epoxy repairs after cleaning treatment), there is a concern of corrosion progression and recurrent failures, so a reliable product is required. ■ The basis for reliability of Corrocoat products ・ Strict surface treatment standards ・ Excellent coating performance and repair technology ・ Repair and regeneration technology for holes, defects, and thin parts

Nickel refining pilot plant corrosion resistant coating trial

■ This product can be used in the pH range of 0-14. ■ Covers up to 110℃ in liquid and 185℃ in air. ■ Can be installed in a short time by spraying application. ■ Even with respect to expansion, contraction, and deflection, which are a concern in large tanks, the coating rate of elongation and thin-film construction provide enough flexibility. ■ Standardization of reinforcement works for tank corners and weld by fiberglass lamination treatment ■ Construction on the flange surface of the nozzle connection
