Introduction
This booklet has been written as an introduction to and a
source of general information on pipe joints.
The flanged joint appears deceptively simple but in fact the
science of flanges and joint sealing is complex and continuously
developing. Sound joints are critical to piping integrity and
plant safety.
A pipe joint thus relies on the skill and application of the fitter
who puts it together. Correct selection of materials, application
of procedures, correct use of tools combined with the fitter’s
skill are all required to ensure a joint of maximum integrity.
But mistakes have happened; choosing the wrong gaskets,
using the wrong studbolts. Such mistakes cannot be ignored.
The purpose of this booklet is therefore to increase understanding
about pipe joints; from pipe specifications and how to
use them, to studbolts and how to identify them.With increased
awareness and knowledge, it is expected that mistakes will be
prevented.
