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 [...]

When you’re searching for bellows for your exhaust system, finding a manufacturer you can trust is a crucial element. Bellows play an integral part in the functioning of your exhaust system. Bellows absorb vibrations to prevent an exhaust system from strain. Finding the proper bellow manufacturer for your system is an essential step in ensuring your exhaust system works correctly. Check out how to choose the right bellows for your [...]

Every industry needs equipment that is reliable. A dependable pipe system gives you peace of mind that your system is flowing smoothly. Expansion joints are a vital component in any pipe system. Installing your custom bellows is the first step in ensuring you have a pipe system that operates effectively. Custom bellows need special handling and instruction due to their flexible material. Learn how to install your custom metal bellows [...]

One form of metal exhaust bellows is an exhaust flex joint. An exhaust bellow is a component in a pressurized pipeline that can absorb various pressures along the pipe system that might cause vibrations and other mechanical problems. An exhaust flex joint is a flexible component for exhaust systems found in all front-wheel-drive vehicles and most all-drive vehicles. The flex pipe absorbs shocks and protects your exhaust system from damage. [...]

Let’s imagine a scenario and see how it plays out: you have a pump in your piping system that has failed repeatedly. The pump has been adequately repaired, installed, and aligned, but it is still experiencing chronic vibration issues. A closer look determines that the vibrations are not being emitted by the pump itself. Instead, it is being affected by other equipment as it traveled down the pipe. So, what [...]

Many types of expansion devices are used in industrial applications. As piping systems heat and cool, they experience changes in length caused by thermal expansion and contraction. This thermal expansion depends on the length of the piping run, the temperature differential, and the alloy of the pipe. Because this expansion and contraction can apply considerable stresses to the piping system, various methods have been utilized to compensate for these [...]

Choosing the right material for your metal bellows is essential. Non-ferrous metals are suitable for many sensing and actuation applications. Still, they can’t be used to handle aggressive chemicals or production lines that place a very high emphasis on cleanliness, such as the food industry. For applications in vacuum chambers, such as vacuum valves, pumps, or vacuum interrupters, the best solution is to use stainless-steel bellows. Uses for Stainless Steel [...]

Many people buy cars with diesel engines because they can carry heavy loads and they’re fuel-efficient. The engine has many integral parts, such as glow plugs and the head gasket. Yet, engine exhaust bellows often get overlooked. This piece will discuss what you need to know about diesel engine exhaust bellows so you can develop a stronger appreciation for your ride. Limit Vibration Every car vibrates when you turn [...]
