An expansion joint’s service life is a central element that can affect its durability and functionality. As engineers create pipe infrastructure, they prioritize proper expansion joint installation protocol that benefits the entire system.
But what are some errors that indicate incorrect expansion joint installation? In this article, we’ll explore the different expansion joint installation mistakes to avoid and their effect on pipe infrastructure.
Incorrect or Missing Support Elements
Supports play a significant role in pipe infrastructure; without the proper elements, pipe systems can accumulate pressure that can move pipelines out of place.
When used in conjunction with an expansion joint, a pipe alignment guide can help control motions and axial movements, ensuring the joint can deflect the vibrations for which was designed. If you do not install the proper support, your pipe infrastructure can buckle under pressure, resulting in premature failure.
Reversed Flow Direction
In the instance of reverse flow in a pipeline, pressure waves reflect and refract with different pipe elements. This reaction initiates the formation of positive and negative sonic waves, causing a rise in internal pipe pressure and exceeding the infrastructure’s threshold.
Reversed flow in pipe systems can also manifest in media contamination and physical damage. When installing expansion joints, remember to include internal liners to help protect pipelines from mechanical damage and protect convolutions from flow impingement.
Excessive Pressure
Pipe infrastructure known for experiencing greater pressure than what an expansion joint can withstand can significantly impact its installation and future service life. During installation, it helps to refer to the manufacturer’s guidelines on what pipelines may require so that you can properly determine the expansion joint most suitable for the project.
Keep in mind that metal expansion joints like those we offer at Triad Bellows can withstand great amounts of pressure while preventing pipelines from suffering damage during thermal expansion.
Undoubtedly, pipe infrastructure is unique and complex! As fundamental supporting elements, expansion joints are necessary for a system’s function. Avoiding these expansion joint installation mistakes can ensure components fulfill their intended purpose for many years to come.
