Interpreting and understanding the ASME B31.3 Process Piping Code was never easy. It’s a design code that requires long years of engineering and design experience to fully understand the requirement of the code. A process plant is predominantly made up of piping. Anyone whose work is related to a process plant needs some basic understanding of the piping designs and fundamentals, regardless of whether he or she works in an engineering or operating company. This course is built to give some basic background understanding of some of the key areas the code design is based upon and to enhance the knowledge of Mechanical Engineers, including new Mechanical Engineering graduates who, although qualified in their own discipline, may not have received adequate training on the design code. The course covers a detailed discussion on piping stresses and materials, which the code assumes the Designer/Engineer has adequate knowledge in these areas.

This 3 days course is designed to meet the needs of Mechanical Engineers from Design, Construction and Owner Companies and focuses on key areas that Engineers seems to have limited knowledge.

Provide a basic interpretation and understanding of the design code in a simplified form
Provide awareness of the code and regulations that governs the design and operation of a plant
Provide basic knowledge of design to engineers and plant maintenance and operation engineers for easy decision making

Who Should Attend
Mechanical Engineers from Engineering and Operating companies who are involved either in the design, construction and operation of a process plant. Professionals who need to add to their current experience and knowledge of the basics of the mechanical piping design code. New graduates who want to learn about the piping code will immensely benefit from this course by setting their basics right at the onset of their career.

Mr. Ganga D. Deka, P.Eng is a registered professional Engineer with APEGGA Alberta and currently works with an Engineering Design Company as a Senior Mechanical /Piping Engineer. He brings with him over 25 years of experience in oil and gas industry with diversified experience in both engineering design and operation. He, therefore, brings with him the best experience from both the sides – from the drawing office to hands-on.

Ganga had assumed responsible positions in with multi-million dollar projects both in greens field engineering design and browns field projects. He had led teams of multi-disciplinary Engineers in design, commissioning, start-up and turn-arounds and clearly understands the needs of people who work in a process plant.

Ganga’s long years of experience in the oil industry gives him a thorough insight to the basics of centrifugal pumps used in process industry. With his versatile knowledge and experience he currently delivers seminars on various mechanical engineering subjects related to a process plant to both young and experienced mechanical and non-mechanical engineers.
