Dilatation and Earthquake (Seismic) Expansion Joints

High-Level Seismic Safety with Flexible Connections

Earthquake and dilatation expansion joints are used at transition points (dilatation joints) between different blocks of buildings. Their gimbal-jointed structure allows movement in X, Y, and Z axes, eliminating mechanical stresses on the installation.

Connection and Model Options

• • Flanged Connection: Standard flanged models for easy assembly and disassembly.
• • Welding Neck Connection: Direct-welded models that minimize leakage risks.
• • Grooved Connection: Quick and secure installation designs specifically for fire-fighting lines.

Applications

Fire protection systems, natural gas pipelines, hospital and airport dilatation crossings, and high-pressure fluid circuits in seismic zones.
