UL FM Grooved Flexible Couplings

Grooved flexible coupling are mechanical pipe joints that allow limited movement of pipes at the connection points. They are specifically designed to absorb vibration, thermal expansion and contraction, and building displacement, complementing the functions of rigid coupling.

Product Introduction

The working principle of the flexible coupling is based on its special "toe" design and elastic sealing ring. While allowing the pipeline to move, its internal pressure self-tightening sealing mechanism can ensure that the sealing effect is even stronger after the system is pressurized, maintaining the water tightness at the connection points.

 

In buildings of specific seismic design categories, the code usually requires that for pipes of a certain diameter (such as ≥2.5 inches), flexible pipe clamps should be used at the top and bottom of the risers, at floor connections, and near building expansion joints to prevent pipe breakage due to structural asynchronous displacement during earthquakes.

Product Features

 • Grooved flexible coupling allows for axial displacement, angular deflection and rotation, and absorbs dynamic stress.

 • The inner edge of the clamp is designed as the "toe part", with part of it inserted into the groove, leaving a movable gap.

 • It is mainly applied in situations where displacement compensation is required: connecting water pumps/water tanks, building expansion joints, and seismic (anti-seismic) design areas
