Sure-Flex 6S138 Flange

It is a mechanical joint that connects two pipes, equipment, or sections of a structure, usually by bolting them together.
They serve several purposes, including providing easy access for maintenance, allowing for expansion and contraction of pipes, and ensuring a leak-proof connection. They have a flat or raised face where the two mating flanges are brought into contact. The face helps to create a seal and distribute the bolt load evenly. They are designed to withstand specific pressure levels.
