Pipe flange gaskets are used for improved joint performance. They are
considered much more superior than the conventional ring or full-face
gaskets. Although pipe flange gaskets are usually used for all normal
water and sewer service, they are especially useful in demanding
services like in very large diameter flanged piping. For specially
designed long-span installations, involving 2 or 3 or more lengths of
pipe or with any underground flanges, flange gaskets are of great help
because they could be subjected to undesirable beam loading.
These gaskets are available in numerous
standard materials in various thickness and hardness options for various
flange sizes. Flange gaskets are also available with adhesive on one or
both sides or without adhesive. Most materials are available starting
at 1/32†thick and can be supplied up to 1†thick. Some manufacturers
supply flange gaskets in wide rolls from which you can cut your flange
gaskets to size. Flange gaskets are also available to your exact
requirements. Pipe flange gaskets are being very frequently used for
flanged joints which are subjected to extreme chemical attacks.
