#910X - Piping System Design and Maintenance
Course Objective
Upon completion of this course, participants will be able to apply the design requirements of ASME B31.3 and the maintenance requirements of API-570 to process plant piping systems. They will also be able to perform engineering audits of designs and procedures that have been developed by others. Finally, they will also have been introduced to the design and maintenance requirements of liquid and gas transmission pipelines.
Who Should Attend?
Engineers who are responsible for the design or maintenance of process plant piping systems.
Course Description
This course is composed of two sections. The first section discusses the design requirements for process plant piping systems. The second section discusses the maintenance requirements for these systems. In each case, the course goes beyond merely repeating the material contained in the governing standards and discusses practical applications and typical procedures. The course also contains sample problems that are worked together and written exercises that are completed by the participants. While the primary course emphasis is on process plant piping systems, certain design and maintenance requirements of liquid and gas transmission pipelines are also introduced.
