A manufacturer needs to test the bellows for strength and leaks before installing an expansion joint or metal bellows into a piping system. Hydrostatic testing is one technique experts use. Essentially, it uses water to see if the expansion joint can withstand the pressure or vibrations it’ll need to endure to operate properly. There are three different methods of hydrostatic testing that joints could undergo. Learn more about how [...]
Metal bellows (also called expansion joints) help regulate pressure, vibration, and movement in applications like piping or exhaust systems. Selecting the right metal bellows for your application can be difficult. You’ll need some expertise in the areas to find the right one. Many different industries use metal bellows in different applications such as sealing, temperature, and pressure. Explore the things you should know before selecting metal bellows. Reliable Manufacturer You’ll [...]
Bellows are an essential component of piping systems, and when they begin to fail, they can cause a failure of the entire system. Leaking is a problem that can occur, but it is possible to check expansion joint bellows for leaks and other failures. Learn how to check your expansion joint bellows for leaks to catch a problem before it occurs. Leak Indicator Sometimes, you can spot a leaking bellows [...]
Expansion joints play a crucial part in many different systems. You’ll find them in piping systems, exhaust systems, and even in aeronautics. They are widespread and help to protect sensitive systems from undue strain caused by high temperature fluctuations and severe or constant vibrations. Find out more about the components that create this ubiquitous device in this guide to expansion joint assembly terminology. Bellows The bellows is the flexible [...]
Properly installing metal expansion joints is vital to ensuring your piping or exhaust system operates well. Piping systems require joints to absorb motion. And anchoring and guiding need correct installation to fulfill this purpose. Learn more with these lessons in expansion joint assembly. Anchoring and guiding both play an integral part in the installation process. Anchoring Anchoring is an essential component when installing expansion joints. Improper anchoring can create [...]
If you have expansion joints in your piping or exhaust system, you might be wondering how their cycles work. Essentially, a cycle is the position movements that an expansion joint goes through as it performs. The number of predicted cycles that metal bellows can perform is the lifespan. Learn how expansion joint metal bellows cycles work to understand in detail the function of this ubiquitous industrial device. Design Primarily, two [...]
Implementing tie rods into expansion joint assemblies can deliver multiple benefits and are one of many accessories available for enhancing the capability of expansion joints. What Are Tie Rods? What are tie rods? In the most common application, you can find tie rods on your car. A tie rod is a bar that connects your steering wheel and gears to the tires of your vehicle. When you turn the wheel, [...]
Metal bellows are ubiquitous in many different industrial systems. Understanding how manufacturers create metal bellows can give you a better idea of what type of bellows will be best for your system. There are two methods to produce bellows: welded or formed, but they both begin with the deep drawing process that creates tubes from sheet metal. In deep drawing, a machine draws in the sheet metal to create tubes. [...]
Many different applications that involve significant axial movements under extreme pressure use externally pressured expansion joints. They can absorb an almost limitless amount of movement. How does this work? The joint is arranged with the flow outside the expansion joint, with the internal part subjected to atmospheric pressure to eliminate pressure instability. In applications where an internally pressured expansion joint would buckle, externally pressured expansion joints can absorb the [...]
Testing bellows for quality assurance is vital. Like biomedical, power plants, and aerospace, various industries need bellows for use in precision systems. They help regulate and monitor critical sensors and seals. Failure of any part of these types of systems will lead to severe consequences. When you’re searching for expansion joints, It's essential to purchase parts from metal bellows manufacturers that include testing. Bellows need testing to ensure they [...]
