摘要

The MULTICLAD is a new generation multilayer rolled products developed at Granges Technology for the most demanding applications, with very high requirements on corrosion resistance and strength. MULTICLAD showed excellent corrosion performance in the previous tests. Small brazed heat exchangers with folded tubes of MULTICLAD material MC96 at 220 urn gauge were build to assess their mechanical and corrosion performance, in comparison to a system with Zn arc spray MPE solution. Burst pressure tests, showed that failure took place at fin window area when pressure increased to 140 bars. No LFM was found. In the corrosion test, the heat exchanger using MC96 with FA6815 fin and FA8U13 manifold, exceeded 120 days SWAAT without leakage and showing only lateral corrosion.
