To improve safety, reliability, and minimize liability of fixed equipment by learning common damage mechanisms in the refining and petrochemical industry as covered in API 571 are the primary objectives. The roles of the engineer and inspector in identifying affected materials and equipment, critical factors, appearance of damage, prevention and mitigation, inspection and monitoring will be covered to introduce the concepts of service-induced deterioration and failure modes. This course is intended for anyone interested in gaining a fundamental understanding of damage mechanisms in metals. Topics covered in this course will also assist API 571 ICP exam candidates preparing to write the certification examination.

Who Should Attend

Engineers, inspectors, designers, and experienced maintenance personnel who are involved in designing, operating, maintaining, repairing, inspecting and analyzing pressure vessels, piping, tanks and pipelines for safe operations in the refining, petrochemical and other related industries. This course will also assist API 571 ICP exam candidates preparing to write the certification examination, although it is not a prerequisite that you be an exam candidate.

Professional Development Hours (PDHs)

Each participant will receive a digital CASTI Certificate of Completion with 32 Professional Development Hours (PDHs) for attending all 4 days of the instructor-ledtraining.

4 Days Instructor-Led Training
API RP 571 ICP Practice Exams - available online after the scheduled instructor-led training
