book, “Stress Corrosion Cracking of Pipelines”, has been published by John Wiley Publishing, U.S.
It is the first book in this area in the world. http://ca.wiley.com/WileyCDA/WileyTitle/productCd-111802267X.html
Dr. Cheng, as the
Guest Editor, has completed the Special
Issue on Pipeline Corrosion for the journal Corrosion Engineering Science and
Dr. Cheng is
coauthoring with Mr. Richard Norsworthy a new
book “Pipeline Coatings”, which will be published by NACE International
Dr. Cheng is an
internationally recognized authority in oil/gas and pipeline corrosion,
materials and integrity. The overall goal of his research is to advance the
mechanistic understanding of corrosion in oil/gas and pipeline systems, and
to develop effective techniques for modeling, assessment, prevention and
prediction of pipeline failures.
Cheng’s research has been driven by industry needs in four
application areas: Downhole tubulars; Oil/gas gathering pipelines;
Oil sands slurry pipelines; and Transmission pipelines.
research interests include:
in downhole environments: Modeling of tubular corrosion in
SAGD/CO2 co-injection and production systems; Corrosion,
microbiologically influenced corrosion (MIC) and fracture of coiled
tubing; Modeling of corrosion of steel tubing in carbon storage.
of pipeline failure pressure by defect assessment: Analysis
and assessment of ILI data and the detected defects by finite element analysis;
Determination of failure pressure of pipelines containing defects;
Modeling of stress concentration at defect under synergism of internal
pressure, soil strain and local corrosion with considerations of steel
grade and defect geometry; Modeling of defect growth for prediction of
remaining service life of pipelines.
failure mode and effect analysis: Shielding of
cathodic protection (CP) by coating failures; Development of standard
tst methods for nonshielding property of pipeline coatings with CP;
Corrosion mechanism and kinetics in thin layer (tens of microns) of
electrolyte under disbonded coating; Monitoring of coating disbondment
by scanning Kelvin probe; Testing and modeling of permeability of
multi-layered coatings to dissolved CO2, O2 and
corrosion of pipelines: Mechanism and threshold values of
AC-induced pitting corrosion on pipelines; AC facilitated coating
disbondment; Shift of CP potential under AC interference and modeified
CP criteria for full protection of pipelins; Online monitoring and
assessment technique for AC corrosion of pipelines.
corrosion of pipelines: Pitting corrosion under deposit; MIC
under petroleum sludge; Modeling of multi-phased lfuid flow and
correlation of fluid mechanics with steel corrosion; CO2 corrosion
fundamentals and parametric effects; Model for prediction of internal
corrosion rate in CO2-containing environments;
Multi-functional inhibitors for anticorrosion and anti-biodegradation.
corrosion cracking of pipelines: Pitting corrosion
and crack initiation on pipelines under CP; Coating failure and SCC
initiation; Local activity of metallurgical features at micro- and
nano-scales and its correlation with pitting corrosion; Welding
metallurgy and its role in local preferential corrosion and crack
initiation; Hydrogen permeatraion and trapping in high-strength
pipe technology: Permeation of petroleum hydrocarbons into
HDPE and th effect on chemical and mechanical stability of HDPE
pipes/liners; Environmental stress cracking of HDPE pipe in ASP
floods; Corrosion and fatigue of reinforcing steel cord in HDPE
coating technologies in oil/gas applications:
Development of inhibitor-loaded smart coating technology;
Super-oelophobic and hydrophobic nanocoatings for prevention of
wax/paraffin deposit in tanks.
Dr. Cheng is leading the development of the Pan-Canadian Strategic
Research Network on Oil/Gas Pipeline Corrosion and Its Management.
Dr. Cheng is working with Trican Well
Services to initiate an Industry Joint Project (JIP) on Microbiologically
Influenced Corrosion of Coiled Tubing.
Dr. Cheng is serving as Treasurer of
NACE Foundation of Canada.
Dr. Cheng is chairing the NACE International Task Group (TG) 521 to
develop a standard for testing of the compatibility of pipeline coatings
with cathodic protection.
