EEC-C1-S3
Dresser-Rand's Engineered Equipment Coatings, were developed primarily for protecting rotating and stationary components that are subject to corrosion. The coating system consist of a multi-layer metallic, ceramic system that provides a galvanic sacrificial base that acts as a second line of defense to protect equipment from corrosive attack. The base coating is sealed with either the C1 or S3 top coat that provides a first line of defense in severe operating environments. This multi-layer combination extends the operating life of unit components and increases online availability. The coating's smooth, finished surface also reduces the ability of water treatment additives and other foulants to adhere to component surfaces.
Applications
EEC-C1 or S3 is designed for application on steam turbine or compressor components to provide protection in harsh operating environments with an operating range of 3-9 pH.
All coating applications are reviewed by Dresser-Rand for applicability to the design and service conditions of the unit.
