Condenser Coating Solutions

Defined One-Stop Solutions

Our expert maintenance solutions for the condenser allows a plant operator to plan and budget efficiently, dramatically extends the lifespan of the unit and contributes to overall efficiency in both energy output and reliability.  

Our vast experience means we have acquired an in-depth understanding of our clients’ concerns and the common problems that arise due to erosion and corrosion along the entire cooling water cycle. The condenser is a highly sensitive and valuable element in the efficient working of a power plant. By providing pioneer, state-of-the-art technology, plastocor® solutions help prevent and repair damage to the condenser tube sheet, tube ends and along the entire tube length.

Damage on Tube Sheets

plastocor® Cladding System for Tube Sheets

Tube sheet corrosion is generally caused by dissimilarities between higher alloy, more noble tube material and the tube sheet metal. This situation is becoming increasingly prevalent as stainless steel and titanium tubes are being retrofitted in older condensers and heat exchangers.

Damage on Tube Ends

plastocor® Inlet System for Tube Ends

Tube materials may deteriorate because of galvanic or microbiological issues. Inlet-end erosion is generally due to turbulence present at the tube inlet before laminar flow is established. Outlet-end erosion may also occur due to outlet flow induced turbulences such as cavitation.

Damaged Tube-To-Tube-Sheet Joints

plastocor® Cladding plus Inlet System

Black-trips, water hammer or partial blockage of a tube sheet are common sources of stress to the tube-to-tube-sheet joint. Small "joint leaks" usually result and are often difficult to locate. By combining the cladding and inlet system, the tube joints are permanently sealed adding 1000kg of joint strength.

Damaged Tubes Entire Length

plastocor® Tube Lining System

The tubes used in steam condensers and heat exchangers are selected so as to provide many years of reliable service. Due to unforeseen operational anomalies, tubes may begin to form pits which can result in tube leaks. In most cases, the affected tubes must then be identified and plugged.

« The coating of tube inlets has proven a true taper transition that does not promote turbulence and further erosion-corrosion damage. »
