In gas turbines, it’s vital that a turbine’s pipe system carries exhaust gas away, downstream from the combustion reaction. This allows for further efficient combustion while safely removing these volatile gases. Expansion joints play an important role in this gas transfer. To learn the unique expansion joint challenges in gas exhaust applications, read this brief guide on the subject. Consistently Extreme Heat First, gas turbines create extremely high-temperature exhaust [...]

An expansion joint’s purpose is reduction of pipe system failures. Though it’s a protective, preventative tool, an expansion joint can fail as well. Failure doesn’t manifest in only one way and results from many possible causes. To learn what these causes are, read these reasons why your expansion joints are failing. Poor Design or Installation The most common cause is poor system design or installation. Even if your expansion [...]

So many industries rely on pipe systems to transfer all manner of fluids throughout a facility. To keep their operations running, gas and oil, manufacturing, and other energy-production industries require a solid pipe system, one that isn’t subject to sudden failure. To protect against failure, typically caused by excessive thermal expansion, companies implement several components to redirect expansion harmlessly. These implements include expansion joints, expansion loops, pipe guides, and more. [...]

Expansion joints mitigate vibrational forces, withstand high temperatures and resultant pipe expansion and contraction, and regulate fluid passage without issue. To keep steady function, these joints require certain hallmark elements. Here’s a brief guide to the basic design of piping expansion joints and how each feature contributes to its function. Bellows The first noteworthy feature is the expansion joint’s bellows section. Expansion joints consist of flanges that secure piping [...]

Expansion joints lend integrity to a piping system in industries as divergent as power plants and marine technology. Concerning the latter category, expansion joints allow cargo ships to release their main engines’ exhaust more easily. To learn more about how they support engine functionality, read more on the role of expansion joints in a ship’s main engine. Hold up to Extreme Temperatures The first role expansion joints play is in [...]

Pipe systems expand and contract when the temperature around them changes. Whether caused by the external environment or the internal fluids that pass through pipes, these temperature changes are frequent. Engineers must plan for these expansions and contractions during the design phase to mitigate the potential damage this causes. Pipe length and material affect the degree of change, but there are also several additional measures engineers can take. If you’d [...]

Listed below are the most common types of pipe expansion joints, their differences, and how each functions. Simple Simple pipe expansion joints specifically withstand axial forces. Axial forces act upon the pipe’s axis. It is like the force used to crush a can of soda by placing your hands on the top and bottom of the can and pushing one hand to meet the other. Mitigating these crushing forces makes [...]
