Description

The Multi-Layer Lined Metal Bellows Expansion Joint with Swivel Flanges is designed to compensate for thermal expansion and contraction caused by temperature and pressure variations in industrial piping systems. It effectively absorbs vibration and reduces mechanical stress, protecting pipelines and equipment while improving system efficiency and extending service life.

The expansion joint features a high-quality multi-layer stainless steel bellows that provides excellent resistance to pressure, fatigue, and repeated movement. The internal liner protects the bellows from erosion caused by high-velocity media while improving flow characteristics and minimizing turbulence. The swivel flange design allows easy installation and alignment with mating flanges without rotating the entire expansion joint.

How to Select the Right Expansion Joint

To ensure optimum performance, consider the following factors when selecting an expansion joint:

* Pipeline diameter
* Operating pressure
* Operating temperature
* Type of service media (steam, water, thermal oil, gases, or other fluids)
* Required movement (axial, lateral, or angular)
* Installation conditions and vibration levels

Selecting the correct expansion joint ensures maximum safety, reliable operation, reduced maintenance, and long-term system performance.
