Introduction

Appropriate material selection is the cornerstone of pressure equipment and piping design, operation and maintenance. Engineers must select materials of construction that provide adequate strength at operating temperatures and pressures, in compliance with applicable construction codes and with regard to their resistance to corrosion and other likely degradation mechanisms, as well as to cost-effectiveness. The acceptability of materials is controlled by the relevant Codes. The ultimate selection of the correct material is the responsibility of the design or fabrication engineer. By listing the design’s allowable stresses, the Codes do limit the materials that can be chosen. Only those materials that meet certain requirements as listed in the specifications should be used. The mechanical integrity, safety, and cost-effective operation of plants depend on the in-service performance of the materials of construction throughout the plant life cycle.

Metallurgy is a complex science but a general understanding of the major principles is essential to the plant engineers and inspectors This course provides comprehensive and practical understanding of engineering materials and guidance on the methods and best industry practices for the selection of the appropriate materials of construction for specific applications while simultaneously satisfying service requirements, construction Code requirements, and least life cycle costs over the entire plant life.

This course will provide a practical overview of ASME BPVC Section II – Materials, as well as some relevant information from the BPVC Section VIII Div.1 and B31.3 Process Piping

This course will provide a practical overview of ASME BPVC Section II – Materials, as well as some relevant information from the BPVC Section VIII Div.1 and B31.3 Process Piping

This course builds on a focused and practical coverage of engineering materials properties and selection and provides a structured approach to predict, monitor and assess the materials performance in service with the objective of ensuring plant integrity, safety and cost-effective operation

Seminar Objectives

The key objectives of this course are as follows:

• Assist participants to clearly understand that the appropriate selection of materials of construction for pressure equipment is the cornerstone of safe, reliable and costeffective plant operation.
• Enhance participants’ awareness of key requirements of relevant design and operation standards and industry practices such as ASME B&PVC and B31.3; ASTM Material Specifications, API 571, 580, 581, 578 and 579, and others.
• Provide guidelines to participants to identify and locate in-service degradation and appropriate tools for condition assessment and making sound run/repair/replace decisions. Make participants recognize that although all flaws detected by inspection must be evaluated, not all flaws need to be repaired. The proper application of API Std 579-1/ASME FFS-1 for fitness-for-service assessment may obviate the need for some repairs and result in reduced maintenance cost and downtime
