INTERNAL CORROSION

For updated courses on internal corrosion and new requirements for ICDA methods, or generally in expanding knowledge of specific areas of internal corrosion or internal corrosion control. The program is designed to round out the students overall information which may be utilized in the performance of his/her job.

Internal Corrosion Sub-Chairman: Karen Bowman

 

Class Descriptions

INTRODUCTION TO INTERNAL CORROSION

Overview of corrosion mechanisms, and the mechanisms that mostly influence internal corrosion. Review of the corrosive constituents that may be present in the water/gas mixture.


PIPE INSPECTION

Explanation of visual inspection in the field (i.e., what to look for and what data to collect).


NDT METHODS

Explanation of different non-destructive testing (NDT) methods (UT, Digital X-ray, Guided Wave, etc.). In-depth explanation of guide wave evaluation for internal corrosion screening.


FIELD SAMPLING AND TESTING

Explanation of field gas and water sampling in respect to internal corrosion. Explanations of pH tests, CO2, H2S, alkalinity, and dissolved O2 water tests.


LABORATORY TESTING

Once field results are complete, a review of the laboratory testing procedures and results for water and gas results relating to internal corrosion constituents.


MONITORING TECHNIQUES AND SELECTION

Discussion of where and when to monitor for internal corrosion.


IC FAILURE INVESTIGATIONS

Discussion of internal corrosion failures and the information needed when performing failure investigations.


IC MANAGEMENT DO’S AND DON’TS

Discussion of what information to use when creating an IC program.


CHEMICAL TREATMENT DO’S AND DON’TS

What must be considered when treating for internal corrosion and how to monitor the effectiveness of the chemical treatment.


IMPACTS OF SHALE GAS

A discussion of what is known about the Shale Gas, a non-traditional gas, thus far. The effects shale gas may have in downstream gathering and transmission systems.


IC ROUND TABLE

Questions from the audience relating to internal corrosion for industry experts.


HANDS-ON SAMPLING

Perform the on-site internal corrosion testing that was discussed in the Field Sampling And Testing class. Part of the Outdoor clinic.
