Gas Transportation Piping Code: ASME 104 – ASME B31.8

This course is designed to give the participants a thorough understanding of Gas Transport Piping Code, ASME B 31.8and its practical use as illustrated with numerous case studies.

About this Course

This course is designed to give the participants a thorough understanding of Gas Transport Piping Code, ASME B 31.8and its practical use as illustrated with numerous case studies. It offers detailed insight pertaining to design, manufacture and inspection of the Piping systems used in Gas Transportation. 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, straight forward manner, including the Short-cut methods in designing of Pipes, Pipe fitting and Flanges. The course is designed such that no previous background in ASME code is necessary. However, those familiar with the code will find the course immensely useful as regards understanding the code by “letter and spirit “and gaining a thorough systematic practical insight of the code. The course is divided into following areas: What is this Code emphasize upon, Introductions to fundamentals of Pipe design, Introduction to various applications of various Steels, Selection of appropriate material for intended application, How to Fabricate, what are Construction precautions and How to Test the Piping System, etc.

Course Objective

Global competitiveness is forcing the need to construct more effective piping system, possible only if one is familiar with existing Design and Engineering practices and knows their correct adaptation in Design, Construction and Testing of piping Systems. This course fulfills this need by addressing the following:

To familiarize participants with the main concepts, and philosophy of the code.
To introduce participants to the concepts of standardization.
To explain to participants the basic and technical terms of ASME Code.
To provide participants step-by step approach in use of this Codes, including the optimization techniques.
To introduce participants with various design conditions, design rules, environmental influences on material selection, fabrication, erection and testing of piping.
When, where and how much to conduct NDT of piping and the acceptance Criteria.
How to Conduct and certify pressure testing
