Coatings are applied to rotating equipment to address corrosion,
erosion or fouling problems which increase the operating and maintenance
costs of a unit and decrease reliability.
Providing OEM Solutions to our equipment owners,
Dresser-Rand is now offering Engineered Equipment Coating
solutions. |

Metallic-Ceramic corrosion protective coatings and Polymeric
anti-foulant
coating applications have been handled previously by D-R vendors. The
problems encountered with vendors understanding of the unique engineering
designs of Dresser-Rand equipment has driven Dresser-Rand in the
development of these specific coatings.
The installation of the coating facility in Tulsa provides our
equipment owners Engineered Equipment Coatings (EEC) to
complement the original design of the unit.
Dresser-Rand’s
EEC product line can be applied to both centrifugal compressors and steam
turbine units. Engineered Coatings applicable for rotating elements and
stationary components are available. Initially, three (3) basic coating
systems were developed to enhance equipment corrosion or fouling
protection. These systems consist of two or more sacrificial layers which
work in combination to protect rotor components. Various top coat layers
are applied to modify the existing surface finish to assist in reducing
unit fouling or chemical resistance.
D-R’s coatings have been developed and tested to survive standard D-R
shop and field component installation procedures. The D-R EEC, temperature
tolerant coatings retain their bond strength and surface smoothness during
typical destacking and stacking of rotor components.
Rotating Equipment
Dresser-Rand’s EEC are designed to provide component
protection from typical centrifugal compressor and steam turbine operating
conditions. Their multi-layered systems are designed with a metallic
filled base coat to provide galvanic sacrificial protection and inert top
and sealer coats to provide additional barriers to product corrosive
attack.
The anti-foulant coating begins with the same base but is topped off
with a polymeric filled coat to increase the lubricity of the operating
surfaces.
Stationary
Component Coating
Coating of stationary flow path parts can provide increased efficiency
if the surface finish is significantly reduced. A factory original surface
finish of Ra 64 is typical, but will degrade over time in operation.
Coating with EEC-C1 (corrosion protection) or EEC-A2 (fouling protection)
will help restore the surface to its original smoothness or better.
Dresser-Rand is offering a "SH" top coat which can reduce the
final surface to a Ra 15 or better.
The Dresser-Rand Advantage
We know the operating requirements of the rotating equipment we design
and can apply our Original Equipment Manufacturing expertise to the
application of our EEC for your equipment solutions.
