Experience the Perfect Balance of Durability, Flexibility, and Performance with Metallic Expansion Joints Designed to Absorb Thermal Movement, Reduce Vibrations, and Enhance the Lifespan of Your Industrial Systems in Even the Most Demanding Environments
Metallic Expansion Joints or Bellows are critical components designed to accommodate the movement of pressurized piping systems caused by thermal growth, contraction, and small vibrations. These joints ensure system integrity by compensating for stresses that occur during operation, reducing the likelihood of damage. By accommodating movement and absorbing vibration, these expansion joints improve system performance and longevity.
Our expansion joints are designed to meet EJMA 9 or ASME standards, ensuring compliance with industry requirements. They are suitable for carrying various media, such as:
Steam
Water
Emission gases
Acids
Alkalis
Hydrocarbons
Types of Metallic Expansion Joints
Metallic Expansion Joints are designed to accommodate different types of movements in industrial systems. Understanding these movements is crucial for ensuring the optimal performance and lifespan of the expansion joints. Below are the key types of movements:
Axial Movement
Axial movement refers to the dimensional change of the bellows along its longitudinal axis. This movement typically includes:
- Compression: The bellows shorten as the piping system heats up or contracts.
- Extension: The bellows elongate due to system expansion or stretching.
Axial movement is the most common type of deflection and is critical in handling thermal growth or contraction in pressurized systems.
Lateral Movement
Lateral movement involves the relative displacement of the bellows ends perpendicular to its longitudinal axis. Key characteristics includes:
- The ends remain parallel but shift in opposite directions.
- Lateral movement can occur in multiple planes.
When lateral deflection happens in more than one direction, the resultant movement is calculated and factored into the bellows' evaluation. Proper assessment is vital to ensure long service life and correct hardware orientation.
Angular Movement
Angular movement refers to the deflection of the bellows' longitudinal axis into a circular arc around its center and midpoint. Characteristics includes:
- It can occur in one or multiple planes.
- Often referred to as rotational movement, it involves angular deflection or rotation.
Angular movement must be carefully evaluated to ensure it does not affect the expansion joint's lifecycle or hardware orientation.
Torsional Movement (To Be Avoided)
Torsional or twisting movement occurs around the longitudinal centerline of the bellows. Important considerations:
- Metallic expansion joints are not designed to absorb torsional displacement.
- Applying torsional movement to the bellows can significantly reduce its lifespan or lead to immediate failure.
It is critical to avoid torsional movement by ensuring proper installation and system design.
