ZT-US Type expansion joints

CONTACT US FOR PRICE

• US type expansion joints are used in flue gas (exhaust) systems.
• For general applications with low pressure and high temperature.
• Designed for small vibrations and relatively large axial and lateral movements.

Vorteile

• Highly customizable design: Bellows geometry, material options and combinations
• Multiply bellows with low spring rate and high cycle life

With loose / swivel flange connection:

• Easy installation, flanges can be rotated
• Flanges are not in contact with medium, which enables lower grade material
• Connection with non weldable materials possible
• Galvanic surfaces/ coatings possible
• Gaskets can often be eliminated
