Vibro Lag Pipe Acoustic Lagging

VIBRO FLEX St.Steel expansion joints are primarily designed to absorb dimensional changes in pipelines caused by thermal movement. They are made of bellows formed from thin-walled stainless-steel tubing. Compared to other methods of accommodating pipe movement, such as pipe loops or slip-type joints, bellows expansion joints are more efficient.

Key Specifications

Pipe loops occupy excessive space, while slip joints demand frequent maintenance. Moreover, both loops and slip joints can only accommodate movement along the pipe axis.

Product Details

Pipe loops occupy excessive space, while slip joints demand frequent maintenance. Moreover, both loops and slip joints can only accommodate movement along the pipe axis. In contrast, bellows expansion joints are compact, maintenance-free, and capable of absorbing multiple types of movement.

VIBRO FLEX bellows expansion joints are offered with flanged, welded, grooved, or threaded ends. Internal liners are available to protect the bellows’ inner surface from erosion and to reduce vibrations caused by fluid flow. Additional options include tie rods for movement control and shrouds that shield the bellows from damage in buried installations. For proper anchoring and guiding of pipelines with expansion joints and to avoid joint extension or buckling due to pressure thrusts consult Akinco for expert guidance.
