Examples of applicable lines

Rubber flexible expansion joints.
- ●When ground subsidence is anticipated
Install on soft ground, roads, river crossings etc. it absorbs mainly perpendicular and bending displacement. - ●When temperature variations are anticipated
Installed on piping where temperature differences, thermal expansion, etc. are anticipated mainly to absorb axial and bending displacement. - ●When vibration and noise are generated
Installed near pumps or turbines to absorb vibration and noise transmitted to pipelines. - ●When multiple causes are anticipated
Products can also naturally be installed when causes among the above occur together. - ●Cases of incompatibility with other TOZEN products
When on-site usage with products of specifications such as the PT Connector, TOZEN Flex, and TOUGHLEX is not possible.
