Failure Analysis of Spiral Plate Heat Exchanger
The comprehensive failure analysis was taken to investigate the leakage initiation of spiral plate heat exchanger. The micro appearance of cracks in spiral plates, chemical composition, metallographic structure, crack fracture and tensile properties were analyzed. The results show that the failure of spiral plates is most likely due to the non-standard design and manufacture combined with alternating load caused by alkali washing.
