A Metallic Expansion Joint is a component commonly used in pipelines to accommodate thermal expansion and contraction. As fluids within a Pipeline experience temperature fluctuations, the metal pipes can expand and contract, potentially causing stress and damage. Metallic Expansion Joints are designed to absorb these movements, allowing the pipeline to expand or contract without causing strain on the system. They are constructed from flexible Metal Bellows that can accommodate the changes in length and pressure, thus preventing damage to the Pipeline and maintaining system integrity. This functionality is crucial in ensuring the longevity and efficiency of Duct line systems across various industries.
● Construction : The Expansion Joint is designed to accommodate thermal expansion and contraction in Piping systems. It features a robust construction with high-quality stainless steel (SS) for durability and reliability.
● Shapes : Rectangular | Square | Circular
● Types : Convolute design, which provides flexibility and accommodates axial, lateral, and angular movements.
● Materials :
# Bellows : Made from high-quality stainless steel (SS) to ensure corrosion resistance and long service life.
# Flanges : Available in both stainless steel (SS) and mild steel (MS), depending on the application requirements.
# Applications : Suitable for various industrial applications where movement and thermal expansion need to be managed effectively.
# Purpose : Designed to absorb movements in the axial direction (along the length of the pipe).
# Construction : Typically consists of a single bellows element that allows for linear expansion and contraction.
# Application : Commonly used in systems where the primary movement is along the pipe’s axis.
# Purpose : Can absorb both axial and lateral movements.
# Construction : The two bellow elements are connected by a middle pipe, which allows for both axial and lateral flexibility.
# Application : Used in systems where the pipe may experience a combination of axial and lateral movements.
# Purpose : Allows for angular movement (rotation) around a fixed point.
# Construction : Includes bellows connected with hinges, which accommodate angular deflections.
# Application : Suitable for applications where pipes need to flex at specific angles, often used in systems with multiple direction changes.
# Purpose : Designed to handle both angular deflections and lateral movements.
# Construction : Uses multiple bellows and support rings arranged to allow movement in multiple directions.
# Application : Ideal for systems with complex movement requirements, offering flexibility in both angular and lateral directions.
