Failure Analysis?
(OP)
Does anyone know, what happen in this material?
What type of that corrosion?
How can this occurs?
This is flowline with some data
-Material : NPS 4, API 5L-B, Sch 40
-Remaining thk : average 1 – 2 mm
-Date of construction : July, 2006
-Operating pressure : 225 psi
-Operating temp. : 80 F
-Service : Gas
-Flow rate : 1.5 – 2.0 MMCFD
-Distance from wellhead : 1.5 Km
-Location : straight line, under ground, before scrubber
-Position of corroded area : 6 O'clock
-Date of failure : Dec, 2008
