Abstract (en)
[origin: EP0679853A1] A coating for tube bottoms (A) and incoming/outgoing coolant tubes (B) in heat exchangers, esp. steam condensers, is based on hardening plastic mixt. (I) and is produced by cleaning the substrate surfaces with abrasive, closing the inlets and outlets with removable stoppers, applying ≥ one coat of (I) to (A), hardening the coating, rubbing down, removing the stoppers, injecting ≥ one layer of (I) ≥ at the entrance of (B) and allowing to harden. The coating in the tubes (B) is reactively bonded to the coating on (A) by matching the application times accordingly, and the coating in (B) has a greater elasticity than that on (A), with an elongation at break (DIN 53152) which is ≥ 2% higher. Also claimed is the above coating process as such. <IMAGE>
