Gasket Facing and Selection

The gasket facing and type correspond to the service conditions. fluid or gas handled, pressure, temperature, thermal shock, cyclic operation, and the gasket selection. The greater the hazard, the more care that should be invested in the decisions regarding gasket selection and facing details.

Facings which confine the gasket, male and female, tongue and groove and ring joint offer greater security against blowouts. Male and female and tongue and groove have the disadvantage that mating flanges are not alike. These facings, which confine the gasket, are known as enclosed gaskets and are required for certain services, such as TEMA Class "R."

For tongue and groove flanges, the tongue is more likely to be damaged than the groove; therefore, from a maintenance standpoint, there is an advantage in placing the tongue on the part which can be transported for servicing, i.e., blind flanges, manway heads, etc. If the assembly of these joints is horizontal then there will be less difficult)' if the groove is placed in the lower side of the joint. The gasket width should be made equal to the width of the tongue. Gaskets for these joints are typically metal or metal jacketed.
