Course Overview
Flanges are very important parts of piping system in oil, gas and process industries. They provide flexibility to break the continuously running very long pipe lengths to insert fittings such as valves of various types (isolation, control, non-return, safety etc), instruments (flow, analysers etc), spectacle blinds, etc. Pipe flanges also allow convenient routing of pipes. Flanges are welded at both the ends of a pipe length, a valve and other fittings.
What is flange management?
Flanges help divide the whole length of pipes in smaller parts which facilitate their removals for easy inspection and maintenance. This includes their replacements for the reasons of corrosion or other types of failures/deterioration. While flanges facilitate the above aspects, they also become pain points as they are potential leak sources in high-risk process industry, e.g. oil, gas and Petro-chemicals etc which contain flammable, explosive and toxic fluids. So, the flanges of the mating pipes and fittings must perfectly match each other at the joints. This will arrest the leakage from their joints.
‘Flange Management and Tightening’ needs special attention by those who are in the hazardous process industry.
Why is flange management important?
Since leakage of fluids in large process industries has huge national and global economic implications, this course on ‘Flange Management and Tightening’ is very important. Only trained personnel must be asked to interface ‘Flange Management and Tightening’.
This Zoe training course will empower attendees with comprehensive knowledge about ‘Flange Management and Tightening’.
