Product Description

The Metraflex V-Loop can be used for both seismic and thermal applications.  Like all the products in the Metraloop family of products, the V-Loop does not develop thrust loads and this results in almost eliminating the need for guides, simplifying anchor design when compared to in line bellows expansion joints.

The Metraloop V-loop has many of the advantages of the standard Metraloop expansion joint.  Although it has a longer footprint, it also has a shorter offset than a Metraloop, allowing installation in tighter spaces.

One operational difference between the Metraloop and the V-Loop is that the return fitting on a V-Loop will move much more than on a Metraloop.

Options

  • Liners for high velocity or abrasive material
  • Exterior coatings for protection in corrosive environments.
  • Double braided for high pressure or steam applications.
  • Any fitting that can be welded or brazed to can be used.

Refer to table for temperature and pressure ratings.

Product Highlights

  • Absorbs both thermal growth and seismic movement in piping systems
  • Does not develop thrust loads like in line bellows, resulting in very low anchor loads and guiding requirements.
  • It takes up less space and takes less time to install than a hard pipe loop.
  • Capable of movement in all directions
  • Available in stock and custom configuration up to 36” diameter
  • Proudly made in the USA
