Crevice Corrosion in a Subsea System — Aspect Before Analysis

ASTM — sub-branches

Aspect of the male part of the coupling, a pin, presenting the thermal spray layer detachment (right side of the figure). The pin was manufactured in a superduplex stainless steel tubular forging; the external surface was partially coated by thermal spray and machined.  The sealing is only elastomeric but a coating is required to avoid galling between the two materials of the coupling.
