Internal Corrosion of gas pipeline
Internal Corrosion of gas pipeline
(OP)
In a recent cleanning process of a Gas pipe line, we have found considerable amount of black powder from the internal surface of the pipe line. Mineralogy sample shows that
Mackinawite (FeS-0.9)- Dominant
Metacinnabar(HgS) - Trace
Halite(NaCl)- Trace
What is the approach to find these compositions are aiding the internal corrosion of the pipe line or not?

MAOP- 10 MPa
Diameter - 169.3 mm
Wall thickness - 4.2mm
Material - API5LX42
Design factor - 0.72
What methods I'll be using to find the mentioned compersitions won't aid the corrosion process?
