About Training

This intensive five-day course is designed to give the participants a thorough understanding of Process Piping Code, ASME B31.3. and its practical use for all aspects right from Piping Design to testing and certification. It offers a detailed insight into code requirements pertaining to the design of Piping components, branch connections, selection of flanges, fittings, flexibility considerations, materials requirements, fabrication, welding, NDT examination, and Pressure testing.

The course will cover the Piping systems typically used in Petroleum Industries, Refineries, Petrochemical plants, etc. The course emphasizes understanding of ‘stated’ and ‘implied’ requirements (i.e. content and intent) of the code.

Important code requirements will be explained in a simple, straightforward manner, including the short-cut methods in designing Pipes, Pipe fitting, and Flanges. The participants would be explained in detail the mechanics of adopting and applying the code rules for day-to-day use in their professional work. Lessons are enhanced by actual in-class problem solving, directly applying the rules and equations of the B31.3 Code for various design and operating conditions.

This training course is the complete answer to the demands of piping engineers to know the ASME B31.3 Pressure Piping Code and Upon completion of the training course, the participant shall be a complete ASME Code Professional.

The course further provides concepts and methods for assuring the mechanical integrity of existing piping systems. It presents an overview of how the methodology of API 570 can be applied to assessing the present structural integrity of the piping system and deciding its fitness for continued service as well as the projected remaining life.

Mandar Mulay

Mandar Mulay has about 20 years hands on experience in design and integrity assessment of Piping Systems, Reactors & Storage Tanks, Pressure Vessels, Power Boiler, and Heat Exchanger. He is well conversant with the major industry codes & standards such as ASME Sec. I, ASME B 31.1, B31.3 , B31.4 and B31.8, ASME Sec VIII, BS-5500, TEMA, API -650, IS 803, API 579, ASME PCC-2 etc.

Major projects closely associated with, in his professional career so far are, Qatar Chemicals, Shell, Castrol India, Reliance Industries, Cargill Foods USA, etc. His proficiency in Power Boiler, Piping and Pressure Vessel Codes enables him to trace the similarities and differences of these codes. He also actively involved as Instructor for programs on the subjects of ASME codes, Integrity Assessment, Fitness for Service, etc.

Along with his career in Engineering and Design Department in a multinational company at a very senior post for the last 20 years, he is also visiting faculty to a well known Engineering College in India for their P.G. Courses in Piping Design and Engineering

Apart from being visiting faculty, He has also conducted several Training Courses ( ASME Sec. I, ASME Sec. VIII, ASME B 31.3 Piping Codes , API 579 FFS code, ASME PCC-2 Repair practices, and Heat Exchanger Design Operations & Maintenance ) in Saudi Arabia, Qatar, Bahrain and UAE for engineers from companies like Saudi Aramco, SABIC group of Companies, Qatar Petroleum, ADNOC, BAPCO, DEWA, Gulf Petrochemicals etc. He has already conducted many times the training courses in API 579, where the participants rated him “Excellent” for these courses.
