To ensure the safety of piping systems in petroleum refineries and chemical plants, it is crucial to adhere to the design and construction requirements outlined in the ANSI codes. The designer, fabricator, supplier, erector, examiner, and inspector involved in the process must possess a thorough understanding of these requirements and apply them diligently to achieve the desired level of safety. Additionally, the plant owner holds ultimate responsibility for complying with ANSI B31.3. Therefore, it is imperative that they possess a comprehensive understanding of the code's intentions and limitations to effectively oversee and ensure compliance throughout the facility.

Course Objectives:

This course provides a background and ANSI code guidance on design, materials, stress analysis, and practical methods and trends in piping and pipe support the design and stress analysis and construction. Essential in producing this desired safety. Also since the plant owner has overall responsibility for compliance with ANSI B31.3, he must likewise have an overall understanding of the intention and limitations imposed by code.

Who Should Attend?

This course is designed for engineers entering the piping design and analysis field; piping engineers requiring background on Code compliance and trends in piping design and pipe supports design and analysis, plant owners, piping fabricators and suppliers wishing to extend their knowledge to induce a supplementary understanding of piping design and analysis. The course also of interest to practicing piping design and analysis personnel interested in expanding their knowledge by interaction with other people, viewpoints, and experience in the field; and supervisory personnel requiring a review on current design and analysis techniques.
