ABSTRACT:
A pipe hanger for hanging pipe lines joined with a coupling which employs a sleeve type gasket encircled and clamped with a flexible metal band and which utilizes bolts to provide the clamping force. The hanger strip is so constructed that it allows use of the clamping force to force the vertical leg of the hanger strip against the gasket, thus creating pre-compression of the gasket at this critical location.
