Expansion joints for pipe accommodate thermal expansion, shock, installation irregularities and load changes in pipe systems. The benefits of expansion joints for pipes are that they reduce noise and vibration and they lower wear and the likelihood of pipe or component breakage.
Expansion pipe joints typically have a bellows middle. They either have a neck which slides over pipes and takes a hose, or they attach by a flange with bolts or screws. A metal pipe expansion joint is common, but there are elastomer, fabric and various other pipe expansion joints as well.
Most expansion joints are round, but some are square or even rectangular. Besides this, sizing differs between plumbing and other applications. Here are a few tips on sizing:
1. For non-plumbing, round pipe expansion joint applications, refer to the diameter.
2. For square expansion joint applications, refer to the width. Rectangular applications require a hight measurement as well.
3. For plumbing pipe expansion joint applications, don't refer to the diameter. Instead, translate the actual diameter to the standard pipe size.
Buy expansion joint components, even for specialty industrial applicationsPipe expansion joint suppliers sell components designed for a wide range of piping applications, as well as vacuum and gas systems tube systems. A flexible expansion joint pipe connector might not only connect pipes and tubes but also attach to other components, like valves. There is a certain degree of interchangeability between applications, but some expansion joint manufacturers cover certain applications better than others.
Compare prices on pipe expansion joints to get the best dealThere are a lot of expansion joint manufacturers. Once you've found what you are looking for, do some price comparisons.
Get custom expansion joints for pipe, as well as serviceEspecially for large industrial applications, repairing expansion joints can save a lot of money over replacing them. Industrial situations also sometimes require custom made parts.
- Some industrial pipe expansion joints have special attachment methods, like weldable ends or the vanstone flange, which compensates for bolt hole misalignment.
