plastocor® Tube Lining as a cost-efficient alternative to retubing
While coatings on condenser or exchanger tubes will not last as long as retubing (5-10 years vs. 20 years), they have their place in the overall operations and maintenance schedule and options portfolio. The coating of 40’000 of up to 25m tubes can be done within the lead time of a typical outage turnaround cycle of 45 days. The costs run in the range of roughly 30-40% of retubing costs.
Can buy your tubes an extra lifespan of up to 10 years
plastocor® tube lining allows you to buy time to budget for retubing, engineer, or make it to the next turbine outage four years away. Full or partial down tube coatings may also be an option to avoid operation unavailability and leakages and reduce fouling and the need for chemical cleaning. Tubes protected with tube lining have had a service life of more than 10 years, in some cases right up to today.
Eliminates heavy metal discharges to the cooling water
In the case of the CEA PHENIX Nuclear Power Plant in France according to ISO1400, the yearly heavy metal discharge was reduced for copper by 8.2 tons, for zinc by 3.8 tons and arsenic by 7 kg, thus improving the water quality dramatically. 100% solid and non-VOC materials on the entire tube length further reduces the need to add chemicals to the cooling water and for chemical cleaning.
