Software interfaces. See also: application binary interface and application programming interface. A software interface may refer to a wide range of different types of interface at different levels: an operating system may interface with pieces of hardware.
The products used to seal these pipe joints are known as gaskets. A flange gasket is the particular style of gasket utilized to create a seal when two flanged pipe ends are bolted together. The most common use for gaskets is in the services industry, where water pipes need to be sufficiently sealed to prevent water leaks, loss of pressure, or external foreign contaminants entering the pipe.
It is usually desirable that the gasket be made from a material that is to some degree yielding such that it is able to deform and tightly fills the space it is designed for, including any slight irregularities.A few gaskets require an application of sealant directly to the gasket surface to function properly. gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression. Gaskets allow less-than-perfect mating surfaces on machine parts where they can fill irregularities.
