Frequently Asked Questions
How do I select the best hose for my application?
- How do I select the best hose for my application?
- The more information you can gather about your needs, the easier it will be to select the correct hose. You’ll need to consider a number of factors: material compatibility, internal and external pressure, temperature of media and environment, size of the mating pipe or connection points, end fitting types, price, and lead time. You should also consider your application’s motion, deflection, offset, velocity, and volume of media. For help selecting the right hose, contact our Engineering team.
- How do I choose the right hose length?
The right length of hose is chosen by the ‘live length’ — the part of the hose that’s flexible and not an end fitting. Once you’ve selected the correct hose type and know its allowable bend radius, consider the factors that determine whether a hose can accommodate the position it’s intended for. This includes angular motion, traveling, or offsets.
- How do I choose the right hose diameter?
The right diameter for your hose is determined by the velocity, temperature, and volume of the media that must move through your system, as well as the allowable pressure you have to do so. Determining the right hose diameter involves multiple calculations, so contact our Engineering team for help with finding the right fit.
- What’s the difference between a PTFE hose and a metal hose?
PTFE hoses are designed to achieve chemical compatibility more economically than hoses made of metallic, rubber, or other materials. Metal hoses are usually used for high pressure and temperature applications, but PTFE has greater chemical compatibility to acids and solvents.
- How are hose assemblies tested?
- Typical testing for hose assemblies includes a visual inspection test, hydrostatic and/or pneumatic pressure tests, dye penetrant test, electrical continuity test, radiographic test, and mass spectrometer test.
- What’s the service life of a new hose?
- The service life of a new hose depends on application, pressure, media, installation, environment, and maintenance. Hose fitting and hose coupling manufacturers offer guidance on hose life based on all of these factors. For help determining your hose life, contact our Engineering department.
- How should I inspect my hose assemblies?
- Just like with any piece of equipment in a process system, you’ll need an applicable preventative maintenance schedule for your hose assembly. These schedules should consider the criticality and environmental impact of the equipment’s service. If you need help, Lamons has tools to support tracking and monitoring of your hose assembly’s life. To learn more, contact our Engineering department.
- How can I extend the life of my hose assembly?
- The key to extending the life of a hose assembly is to properly evaluate the application and service, and to choose a compatible hose. Proper installation, care, and maintenance of your hose assembly will also help to extend its life. Different applications and services also require different installation procedures, care, and maintenance cycles.
