Course Description

ASME Process Piping


Course Overview:


Compliance with ANSI/API code requirements for design and construction is needed to assure the safety in petroleum refinery and chemical plant piping. The designer, fabricator, supplier, erector, examiner, and inspector’s understanding the application of these requirements is essential in producing this desired safety. Candidates shall learn the ASME Specification and how to use it. How to specify and select valves, flanges, pipes and use of P&ID’s.This course will also provide a background of ASME / API code guidance on design, selection of materials, fabrication, testing and practical methods and trends in piping design and construction.


This course is designed to give the participants a thorough understanding of Process Piping Code, ASME B 31.3. Flange code ASME B 16.5, Valve standard ASME B 16.34 as well as it will cover piping layout Engineering. This course will be of interest to everyone working in any plant where piping is present, be it Refinery, Chemical, Petrochemical, Power and Utility. Course deals with the various P & IDs, Equipment Plot Plans, Piping Arrangements and Fabrication Drawings. This will include pipe sizing, piping specifications and isometrics including valves and fittings, piping hangers and supports.


Who should attend?


This course is designed for engineers entering the piping design and fabrication; piping engineers requiring background on code compliance, piping fabricators and supervisory personnel requiring a review on current design and fabrication techniques and procedures.


Course Duration: 5 Days
