What is the Purpose of Expansion Bellows?
Consider a metal pipe in a factory that swells and shrinks in response to system temperature changes. That pipe would burst, warp, or crack if it had no space to move. Here comes the unsung hero of engineering systems: the expansion bellows . These adaptable connectors are essential for controlling pressure variations, thermal expansion, and mechanical stress. What what do they do, though, and why do they matter so much? Let’s dive into the world of expansion bellows and break it down in the simplest way possible. Understanding the Basics The Mechanics Behind Expansion Bellows Fundamentally, expansion bellows are flexible couplings that are inserted into ducts or pipe systems. They are made to absorb movement, whether it be angular, lateral, or axial. They can flex and stretch because of their accordion-like nature, which relieves the strain on the remainder of the system. Key Components of an Expansion Bellow Most bellows consist of: Convolutions (the flexible part) E...
