- INTRODUCTION
The cost of leaky joints in industry today is staggering. Out-of-pocket
costs run into billions of dollars annually in lost production, waste of energy,
loss of product and, most recently, impact on the environment. These
problems are increasing, not decreasing. It behooves all of us to consolidate
our knowledge and experience to solve or at least minimize these
problems. This publication is being produced because we, as gasket
manufacturers and suppliers, are constantly called upon to solve sealing
problems after the fact. Toooften we find insufficient time and attention has
been given to:
. proper design of flanged joint
. installation procedures and
. selection of the optimum gasket material required to solve a
particular sealing problem.
We will endeavor to outline in this publication those areas we believe to be essential in a properly designed, installed and m"aintained gasketed joint.
We believe most people involved with the design, installation, and maintenance of gasketed joints realize that no such thing as "zero" leakage can be achieved. Whether or not a joint is "tight" depends on the sophistication of the methods used to measure leakage. In certain applications the degree of leakage may be perfectly acceptable if one drop of water per minute is noted at the gasketed joint. Other requirements are that no bubbles would be observed if the gasketed joint was subjected to an air or gas test underwater and a still more stringent inspection would require
passing a mass spectrometer test. The rigidity of the test method would be
determined by:
. the hazard of the material being confined
. loss of critical materials in a process flow
. impact on the environment should a particular fluid escape into the atmosphere
. danger of fire or of personal injury
All of these factors dictate proper attention must be given to:
. design of flange joints or closures
. proper selection of gasket type . proper gasket material
. proper installation procedures
Care in these areas will ensure that the best technology goes into the total package and will minimize operating costs, pollution of the environment
and hazards to employees and the general public.
