ABSTRACT:
A flexible metal piping assembly includes a body with corrugations having spiral (helical) or annular configurations. End connections are mounted on the body ends, which can be flanged or male-threaded. A layer of insulating or sealing material can be applied over the body. The end connections can be male-threaded or female-threaded. A bellows configuration is provided with annular corrugations which taper in proximity to the body ends.
