The Importance of Expansion Joints in Piping Systems
Types of pipe expansion joints systems are used in practically every industry today to carry fluids and gases from one place to another. This is particularly true in power generation facilities, industrial plants, refineries, hospitals, factories, and even restaurants and hotels! Expansion joints are very important components of the piping system as they allow for the expansion and contraction that occurs due to temperature variations without stressing the pipe or causing damage to it. When choosing an expansion joint, you need to consider some factors. In this article we will discuss these factors as well as some considerations when choosing an expansion joint for your piping system.
Uses of Pipe Expansion Joints
Pipe expansion joints are widely used to protect piping systems from thermal expansion and contraction. They provide spacing in pipelines at points where there is thermal expansion, which takes place when temperature rises or drops quickly. When a piping system is subjected to extreme temperature changes, it undergoes a change in length. This change can create sharp edges and stress points that can damage pipes and other components of a piping system.
Where Should They Be Installed
In most cases, expansion joints are placed at either end of pipe runs that experience thermal expansion and contraction. If a continuous length of piping will be affected by temperature changes, an expansion joint should be placed before and after any fittings along that run. The expansion joint should be fastened to either straight or curved pipe so that movement is not inhibited. When installing an expansion joint into a run, it is best to leave as much room between it and surrounding piping as possible for ease of installation and future maintenance.
Types of Expansion Joints
There are two types of expansion joints: mechanical and thermal. Mechanical expansion joints, which feature a gap between two pipes, can be used to absorb movements caused by thermal effects and construction procedures. They often resemble pipe hangers. Thermal expansion joints are made from elastomeric components, like rubber joints, and allow pipe systems to expand over an elongated distance without putting pressure on other parts in a piping system.
How to Choose the Right Material for Expanding Joints
Expanding joints, also known as thermal expansion joints, are used to relieve stress on pipes and hoses caused by temperature changes. They’re used to make a piping system expand and contract without causing damage to it. The type of material used for expanding joints depends on how long you want them to last and how much space is available. Some common materials include: aluminium, cast iron, carbon steel, copper, brass and stainless steel.
When Do I Need Them?
There are three main instances where expansion joints are essential: 1) when heat is generated inside a piping system, 2) when pipes expand during temperature changes, and 3) when pipes are subjected to a great deal of force or pressure. If you’re building an industrial facility that produces heat and has pipework that expands or contracts during temperature changes, you’ll need expansion joints.
