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.
The flanges attach to duct end and have integral mastic which allows the flange to seal itself to the duct. Corner pieces add rigidity to the flange, hold the ductwork together and provide a sealing surface for the gasket. The gasket serves as a seal between the flanges. The cleat insures even compression of the gasket along the length of the flange. Companion Angles (F) Companion Flange or Angles â Angle frames are riveted, bolted or welded to duct ends and are then bolted together with gaskets or caulking to prevent air leakage. Recommended for use where duct sections must be removed periodically. Angle iron flanges are standard mild steel.
