Predict-Pipe 4.3 – Pipeline Corrosion Prediction and Prevention

• An ionic, pH computation module that accounts for the effects of 16 different anion and cation species

• Rigorous water phase behavior calculations coupled with the ability to account for the effects of glycol (MEG, TEG and DEG)

• Wet-Gas ICDA module to model onshore and off-shore natural gas pipeline systems carrying wet gas that may often contain produced or condensed water (Not covered by DG- ICDA)

• Advanced flow modeling and ability to correlate wall shear stress effects on corrosion rate 

• Ability to accurately determine scaling effects due to formation of iron carbonate and iron sulfide scales as a function of temperature and pH

• pH prediction module that facilitates accurate inlet and outlet condition characterizations

• Corrosion prediction based on aqueous CO2 / H2S data.

• Ability to accurately characterize role of oxygen concentration in corrosive systems

• Improved rules to account for variation of water content in oil and gas systems (production and transmission).

• NEW! CO2 and H2S Concentrations can now be entered with very low values

• NEW! Improved pressure drop calculations

Predict-Pipe 4.3 is built upon a framework of standard industry practices (NACE SP0206, SP0110), proprietary data from hundreds of laboratory tests that constituted a Joint Industry Project (JIP) on multi-phase CO2/H2S corrosion and the industry’s most comprehensive database on steel corrosion rates. The software incorporates environmental (electrochemical) as well as fluid dynamic parametric effects on corrosion.
