Dear All
I am keen get your advice or perhaps case studies for potential pitting rate of Duplex X changer tubes with nominal of 1.7 mm. Most of the literature I have seen are based on seawater, which would not fit my conditions
Operating Conditions :
1. Multiphase fluid (mainly oil)with 1.8...
Dear All
Whilst there's strong evidence that pipeline deposits lower the inhibitor concentration and coverage, I am curious to see evidence of field experience supported (not laboratory )corrosion rates for under deposit corrosion under the following :
1. Export Condensate with no threat of MIC...
Dear All
I am planning of modelling CO2 general corrosion on an export Condensate Pipeline(Cassandra) My understanding is that both CO2 content and Pressure input data should be from the last stage separator (where the gas is in equilibrium). I have seen a number of reports (from...
Dear all
I have been asked to evaluate if it's possible to utilise an existing 316 SS tank for a polymeric hydrate inhibitor containing either seawater or 4% sodium chloride solution.
I highly discourage this given the enormous risk of pitting and crevice corrosion. The piping downstream of the...
Just a quick question regarding fillet welds. We are observing low fillet weld throat (2.0 mm) on a 0.75" offtake pipe with 5.56 mm nominal wall thickness. Design Pressure is 28 barg and 3 mm CA.
I calculated the theoretical weld throat using B31.3 The calculated theoretical weld throat is 4.29...

Dear All,
We recently had tube pitting failure on Incolloy 800 tubes with incoloy 800 clad tubesheet. The pitting occurred inside out and upon ECI inspection widespread pitting was found with upto 60% wall thickness loss. Black adherent solid was also found in the tubes. We were lucky to get...
