Axial Expansion Joint and Vibration Damper

The Axial Expansion Joint and Vibration Damper Haenke is a state-of-the-art engineering solution, designed to absorb axial compression or extension movements in straight stretches of piping. This model is ideal for installation between fixed points with axial unidirectional guides, efficiently containing the effects of joint pressure reaction forces.

High Quality Materials

Manufactured with a stainless steel bellows and internal stainless steel guide, this expansion joint guarantees high strength and durability. The terminals can be made of carbon steel or stainless steel, providing flexibility in the choice of material according to the specific needs of the application.

Model Varieties and Compliance with Standards

Available in standard models, such as H-AEJW - Axial Expansion Joint (WPT - weld point terminals) and H-AEJF - Axial Expansion Joint with Flanges, these products comply with ASME B 16.5 150# and EN1092-1 PN10 standards. In addition, we offer options with a galvanized carbon steel tensioning structure for greater resistance.

Mechanical and Sound Vibration Reduction

The Axial Expansion Joint is also designed to absorb small amplitude mechanical vibrations, making it ideal for reducing or eliminating mechanical and sound vibrations from equipment such as suction and booster pumps, turbines, fans, piston engines, compressors, among others.

Specific Models for Vibration Damping

In our standard line, we present the H-VDEJW models - Vibration Damping Expansion Joint (PPS - welded ends) and H-VDEJF - Vibration Damping Expansion Joint with Flanges, both in compliance with ASME B 16.5 150# and EN1092-1 PN10 standards.
