Joints gaskets

Casing Joint Gasket. A confined-type nonashestos gasket suitable for corrosive service shall he provided at the casing joint. 

Differential expansion must be accommodated by an expansion Joint. Gasket failure can allow tube-side fluid to escape to the atmosphere.

Crevice corrosion normally exists in areas such as lap joints, gaskets, and around bolts and rivets. Crevices are also created by deposits of corrosion products on the surface, scratches in the paint film, and so forth. The environmental conditions in the crevice can change over time which become suitable for the nearby clean surface. Crevice corrosion is sometimes attributed to one or more of the following ... 

Reusing of ring joint gaskets is not recommended due the probability of work hardening of the gasket material.

For instance, the buildup of scale within storage tanks and piping may result in situations where corrosive agents can accumulate and accelerate a very vicious hidden corrosion process. One particular example of such conditions that became extremely important after the energy crisis of the 1970s is what is called corrosion under insulation (CUl). However, the same problem exist in maybe a less severe fashion for structural details used in the construction of a system including lap joints, gaskets, and enclosed places that cannot be accessed. 

Other important applications for anaerobics include the sealing of threaded pipe joints, gasketing, structural adhesives and the bonding of slip fitted cylindrical parts (often called retaining compounds). 

When mechanical assistance is required to create a joint, there are a few additional considerations to keep in mind. Installers must be sure that the spigot end of a pipe is not inserted too far into the bell end of a pipe. There is some risk of existing joints being damaged if too much force is used to join pipe sections. Many problems can arise if excessive force is used to create a joint. Gaskets can roll up and cause a poor connection. The pipe beU might split. A pipeline might not pass an air test if excessive force is used to create joints.
