■ Within 260℃: Corrothasne XT
Coating process
■ Existing items: Surface preparation, cleaning treatment, corrosion-resistant coating application.
 Venture / thinning part: Glass fiber laminating treatment
■ New Items: Surface preparation, cleaning treatment, corrosion resistant coating application.
Merits of this application
■ 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.
Corrocoat Japan credentials etc
■ Even now, 12 years after applying the coating, the strength is maintained and is adopted as a permanent measure.
■ Based on performance evaluation, the linning application is still being adopted.
■ Especially, the coating work on the 230℃ lines is highly recognized by the customer.
