Important selection considerations and tips on correctly installing your Swagelok hose
System pressures changes: Be sure to allow sufficient hose length to accommodate changing system pressures.
Previously on the blog, we talked about how there is a lot more to selecting a hose than most people realize. There is also a lot more to installing a hose. Here are 7 installation tips that will help extend the life of your hose and prevent premature hose failure.
Take into consideration hose movement, system pressurization, and thermal expansion when determining hose length. Installing hose that does not have sufficient length to accommodate these factors may reduce hose life.
Minimum bend radius
Follow minimum bend radius requirements for your hose. The Swagelok hose catalogue and most other hose manufacturers' catalogues list the minimum bend radius for each hose. Installing hose with smaller bends may kink hose and reduce hose life.
Hose rupture or leakage
Hose Rupture or leakage may result from bending too close to the hose fitting end connection.
Elbows and adapters can be used to relieve hose strain.
Distribute movement and prevent bends smaller than the hose's minimum bend radius by providing sufficient hose length.
Allow for changes in length resulting from machine motion and tolerances.
Bending in one plane
Avoid twisting the hose by bending it in one plane only. For a compound bend, use multiple hose pieces or other isolation methods.
However, the two most important considerations are length and minimum bend radius. It's a good idea to ensure that both elements are appropriate for the application prior to ordering or installing them in your system. Download the Swagelok Hose and Flexible Tubing Catalogue for more information.
