This is an economical expansion joint for low-pressure applications that require lateral movement beyond that of a single bellows. This style eliminates two welds thus a true cost saving.
ANSI B16.5 forged flanges can be supplied in all available alloys and pressure classes. The raised face can be removed to provide a flat face with any desired finish....
Although similar to a universal joint, dual bellows expansion joints do not have lateral motion capabilities. They are placed in the center of a long piping run to absorb large amounts of axial movement. An anchor base must be used to make joint function properly. ...
Universal expansion joints can be built with victaulic groove nipples to clamp into a victaulic pipe system. All available materials can be furnished. ...
