Gaskets Handbook – 1st Edition July 2017

Successfully sealing a bolted flange connection is dependent on all components of a well-designed system working together, effectively and safely. This Handbook provides technical information on gaskets as a constituent part of a bolted flange connection, typically employed in chemical, petrochemical, refinery, power plant and other industrial facilities. It includes guidance to plant engineers on specifying gaskets; maintenance operators on installing and trouble-shooting bolted flange connection leaks, as well as purchasing personnel on the important functional distinctions between various gasket types.

Contents include definition of mechanical considerations for a bolted flange connection, important considerations for flanges, fasteners, and installation best practices; with a focus on gasket selection and gasket-to-flange system interaction. Gasket storage and handling also are addressed. This Handbook is arranged and detailed to serve as a useful tool for those who presently use or are interested in using gaskets. Contents are organized for the reader to quickly and efficiently find the information needed, while still maintaining important technical detail. It is intended to complement plant approved documents. This Handbook does not address compliance requirements of regulations specific to a particular industry, facility, or regulation body; therefore, readers should consult appropriate local, regional, national, or federal authorities for precise compliance requirements.

It is essential to note that the condition and maintenance of the connection will affect and cause variations in the results obtained from installation and use of any gasket. Readers must ensure products and procedures are suitable for their specific application by reference to the manufacturer.
