Uses, Applications, And Advantages Of Metallic Expansion Joints

By Ryan Olson


It is not often that we contemplate the inner mechanisms of the structures and things that we most likely take for granted. After all, we tend to see things as they are on the dot. When one sees a bridge, a railway track, or a piping system, their similarities may be deemed nugatory and even nonexistent. There is one quintessential resemblance, however, in that they all have Metallic Expansion Joints.

All kinds of rules of physics affect the shape and configuration of most phases of matter. When subjected to the vagaries of temperature, for example, materials expand and contract accordingly. For instance, when exposed to heat, the kinetic energy of its sub particles causes translational excitement in the system, causing the object to expand. This wouldnt jibe well with solid materials in particular, since constant variations in its framework can actuate to fissures and cracks and may cause the structure to eventually collapse.

Metallic joints are also called compensators, most aptly. This is because they take up the strain of thermal expansion and contraction, pressure, vibration, and all other impelling mechanical forces. They are installed in pipe works, duct systems, energy production, water treatment, chemical industries, and energy production sites.

Compensators are mainly constructed of stainless steel and high grade alloys such as nickel. Various designs are available for ones choosing, and they can even be customized for the finicky customer. Whatever the variations, however, theyre always composite of some or other of these components. There are the flanges, tie rods, hinges, wire mesh, welding ends, external, cover, insulation, inner sleeve, and, most importantly, the bellows. The last are elastic vessels made out of a thing gauge substance that works as a shock and pressure absorber.

Compensators have a wide range of heavy industrial applications. When choosing a compensator, one would first have to factor in the mechanisms his particular system will be using. There are, in the main, three kinds of joint movements, the axial, angular, and lateral, and they all wear on the pipes in different ways.

Metallic compensators are advantageous because they have a relatively low installation costs. They can also take up little space. There is also the energy efficiency factor, not to mention its versatility in accommodating all kinds of stress and pressure movements. Metal is also durable, so only minimal maintenance is necessary.

The primary types are the universal, single, inline and elbow pressure balanced, externally pressurized, gimbal, toroidal, hinged, thick wall, rectangular, and slip type. Some types absorb one kind of movement better than others. They each also have their own advantages and disadvantages. There are industries and applications in which one or some of them are principally used, as in duct work, containment vessels, and stream lines.

However, these trusty gizmos are also liable to system failure. The damages may be incurred on the factory, if the manufacturer is not circumspect and responsible enough, or in the handling and shipping thereafter. Or else, the fault may be attributed to faulty installation and nonexistent maintenance.

Compensators are important in that they ensure the flexibility, structural integrity, and reliability of a particular structure. The moot point here is on the long service life and operational reliability of the joints, since they can be burdensome and expensive to replace. One must therefore have a basic understanding of their functions and particularities, and in the process, choose the correct service provider to help them in the design and selection process.
