BOLTED FLANGE JOINT INTEGRITY

Overview

The Bolted Flange Joint Integrity Online Course from Wilkinson Coutts aims to equip professionals with essential knowledge and practical skills to achieve reliable, leak-free bolted flange assemblies. In high-pressure settings such as power plants, refineries, and other industrial systems, maintaining the integrity of bolted flanged joints is vital for safety and efficiency.

This course covers bolted flange joint technology, from flange and gasket selection to fastener types, sealing face finishes, and bolt tightening methods. It examines real-world challenges faced by flanged joints under pressure, temperature, vibration, and over time, emphasising the interactions between flanges, gaskets, and bolts.

By exploring the principles of flange assembly, pressure testing requirements, and troubleshooting flange leakage, the course equips participants with the skills necessary to make informed decisions and prevent costly, potentially hazardous failures in pressure systems.

Whether you are an engineer, plant technician, or maintenance professional, this course will help refine your approach to bolted flange assemblies and ensure the long-term integrity of your pressure systems.

Upon successful completion of this course, delegates shall be able to;

Explain the working principles of a bolted flange assembly
Describe the various types of flanges and how these types must be suitable for a pre-determined condition
Describe the differences between the flange sealing faces and surface finishes
Understand the pressure testing requirements and the differences between the kinds of pressure tests used
Describe the different types of a gasket and these are identified
Describe what a fastener is and understand the thread design and terminology
Understand the principles of flange assembly and the effects of friction
Explain the differences between holt-bolt and half-bolting and the associated considerations for using one of these procedures
Demonstrate how to verify compliance of a flange face with in-service damage
To improve awareness of the causes and troubleshooting approaches to identify flange leakage
