Winn & Coales Coating Protects Power Station Header Boxes

header boxes

Universal Heat Transfer Ltd (UHT) of Atherston, Warwicks, are heat exchange and transfer specialists in supplying equipment and services to industry. One of their latest projects involved the manufacture of header boxes and channel heads for the refurbishment of four hydrogen coolers for a power station generator cooling system.

UHT’s customer specified Winn & Coales (Denso) Ltd’s Archco-Rigidon 403D to give “fit and forget” corrosion protection of the carbon steel substrate from the coolant inside the header boxes for a minimum of ten years.  Winn & Coales checked the specification for both suitability of Archco-Rigidon 403D and also for the method of application, given that the coating had to be applied in normal engineering workshop conditions. UHT say that the coating arrived in a timely manner, which was appreciated due to the tight deadlines they had to meet.

The glass flake vinyl ester Archco-Rigidon coating was inspected by UHT’s customer’s Quality Assurance consultants and found to be more than adequate in  terms of finish and film thickness, including Holiday detection readings, to provide the required protection.
