Introduction

The course provides participants with the knowledge in:

Familiarize participants with the functions and applications of safety relief valves, their types, designs and components.
Enable appropriate safety valve sizing and selection for liquid, gas and vapor applications
Train participants to install, inspect, test & troubleshoot a variety of safety valves.
To increase the participant’s awareness and understanding that the mechanical integrity of relief valves depends jointly on the proper design, operation, condition assessment, and maintenance of the equipment.
To provide the participants with a clear understanding of the degradation mechanisms that relief valves could be subjected to over their operating life, how to identify them, predict and determine their impact, and what appropriate measures can be taken to prevent and control the resultant damage.
To provide the participants with the knowledge and failure analysis skills they need to conduct damage and failure analysis so as to prevent similar failures from happening.
To understand requirements of industry codes/standards and approval authorities.
In-situ Testing Techniques – Onsite Testing of Safety Relief Valves.
Emerging Technologies in Pressure Relieving Devices
Use Valve Star / PRV size software for Safety Relief Valve Sizing & selection from Leser and CROSBY.
