Whether it's in reference to chemical processing, water treatment, commercial plumbing, or other types of systems, leak prevention is essential. Leaks can lead to contamination problems, water damage, financial loss, and a world of other issues you don't want to venture into. Leaks can happen for many reasons, including lack of maintenance, physical damage, wear and tear, and more.
While proper installation and maintenance and timely repairs are essential in preventing leaks, you will also benefit from properly using expansion joints within the system. Expansion joints help to reduce water pressure and high temperatures while also reducing stress and thermal expansion of your pipes. Each of these things is important in preventing pipe failure resulting in leaks and water damage.
If you want to know more about expansion joints and how they can benefit you, you've come to the right place. This article will give you a crash course on how expansion joints work, the different types, and where to get high-quality joints for your piping system.
What are Expansion Joints, and How Do They Work?
Pipe expansion joints are an invaluable component in commercial and industrial piping systems. They're often referred to as flexible connectors because of how they're designed or compensators because of what they do. Depending on the industry, expansion joints are typically installed an average of 15 to 25 feet apart, and each joint is roughly a foot long.
Expansion joints are often made of flexible materials that can expand and contract when there are fluctuations in flow or temperature or when there is unexpected expansion, movement, or vibration of a pipe system. In this way, they relieve sudden pressure changes that could cause solid pipes to burst.
Expansion joints are used in a wide range of piping systems, including:
- Commercial plumbing systems
- Chemical processing systems
- Nuclear and non-nuclear power plants
- Food and beverage manufacturing plants
- Gas and oil refineries
- HVAC systems
- Many more!
Essentially, any industry that relies on pipes to transport water, gas, oil, chemicals, or other gases and liquids should utilize expansion joints in their various piping systems.
Types of Expansion Joints and Their Uses
While all expansion joints perform similar functions, there are several different types to choose from depending on your needs.
- Rubber Expansion Joints - When you need expansion joints that are flexible and absorb vibration, rubber expansion joints are the way to go. These joints are very flexible and are often utilized in the HVAC, plumbing, and water treatment industries.
- Metal Expansion Joints - For a more heavy duty and durable option, metal expansion joints are a good option. Metal expansion joints are ideal for high-pressure and high-temperature situations, such as in the chemical processing or power generation industries.
- Fabric Expansion Joints - Fabric expansion joints are designed specifically for use in ducting systems to handle gas flow.
- Teflon Expansion Joints - If you're worried about corrosion due to moisture or chemical exposure, Teflon expansion joints are a good option. As such, they're a popular option for chemical processing, food and beverage production, and energy production.
How Expansion Joints Prevent Leaks
The main reason that engineers love expansion joints is because they help prevent leaks in commercial and industrial pipe systems. Here's how:
Absorbing Pipe Movement
One of the biggest leak risks in commercial piping systems is when the pipes suddenly move or shift. This happens because of thermal expansion, pressure changes, vibration, contractions, or human interaction. Without expansion joints to absorb the movement, this would cause pipes to fail, resulting in leaks.
Stress Reduction
Through the years, piping systems experience a ton of stress on their welds and joints. This can happen for a wide range of reasons, including vibration, pressure and temperature changes, or simple wear and tear. Expansion joints reduce this inevitable stress and keeps your pipes from faulting.
Damage Prevention
Lastly, expansion joints help prevent damage that commonly occurs when a pipe system experiences mechanical vibration or pressure surges. Vibration and pressure changes cause piping systems to suddenly expand or move, which can loosen welds and crack pipes. Expansion joints keep this from happening.
Best Practices for Selecting and Installing Expansion Joints
There's no doubt that expansion joints are invaluable in piping systems. However, because there are many different types of expansion joints, it can tough to select the right ones and install them correctly. Here are a few best practices to abide by:
- Consider your primary needs with expansion joints, whether it's handling vibration, movement, pressure changes, temperature changes, chemicals, or corrosion.
- Make sure the expansion joint you choose is compatible with your pipe material.
- When installing expansion joints, make sure they align perfectly with their connecting pipes.
- Choose joints that are the right size for your pipes.
Maintenance Tips to Ensure Longevity and Leak Prevention
If you want your expansion joints to last as long as possible, here are a few maintenance tips to keep in mind.
- Have your joints regularly inspected for stress, wear and tear, or damage.
- Signs of wear and tear include cracks, corrosion, leaks, and bulging or flattening in the joints arch or bellows.
- Inspect, clean, and replace the bellows as needed.
- Avoid using harsh chemicals when you clean expansion joints.
- Pay extra close attention to joints operating in harsh conditions, such as excess humidity, extreme temperatures, rain, and snow.
