Many industries rely on water hoses for their operations. They can safely convey dangerously hot (or cold) liquids, and they can also move steam.
To most people outside of the hose industry, [industrial hose" is a catch-all phrase for any hose that doesn`t deal with hydraulic fluid. But that`s a little misleading.
Types
Industrial hoses are used to transport liquids, gases and sometimes solids in a variety of industries. They are available in a wide range of sizes and pressure ratings. They are also constructed of a variety of materials. Choosing the right hose for your specific needs is important. Using the wrong hose could lead to chemical exposure, fires, floods or explosions.
Types of plastic hoses include PVC and polyurethane. They are resistant to chemicals, high temperatures and abrasion. They are also lightweight, flexible and kink-resistant.
Metal hoses are available in stainless steel and brass. They are able to handle a wider variety of chemicals than other types of hoses. They can also withstand higher temperatures and are more durable than other hoses.
Other types of hoses include flat hose, beverage hose and spray hose. Flat hoses return to their flat shape when empty and are easy to roll up for storage. They work well for hand-watering, sprinkling and drinking water.
Materials
Industrial hoses handle air, water, chemicals, petroleum products, waste gases and bulk solid materials. They are designed with durability in mind to ensure maximum value for your operation with minimal downtime and maintenance.
The term "industrial hose" may be confusing to those who are not in the industry. This is because it includes everything that isn't metal, Teflon or hydraulic hose.
Composite hoses are durable, lightweight and cost-effective, with elevated safety ratings. They can be used as suction or discharge hoses and are made from a combination of rubber, polypropylene films and polyester vapor barriers to resist corrosion and harsh media.
Neoprene is another commonly used material in a variety of industrial applications. It functions well in a wide range of temperatures, resists oils and chemicals, and has low toxicity. It is also known for its high tensile strength and durability. Industrial hoses can be crimped, swaged or clamped to end connections, depending on their application and desired fit.
Pressure Ratings
For optimum performance, an industrial hose must be properly rated for pressure and temperature. This is impacted by the application, environment and system components such as hose fittings and clamps. It is also influenced by hose design factors that allow for appropriate specifications and assembly processes.
As temperatures rise, maximum rated working pressures of the hose and end connections can diminish. This requires that the hose be derated based on its temperature rating, or that the hose assembly is specified to run below its maximum working pressure.
The fabricated hose should be proof tested during the assembly process to ensure that it is leak free and has the strength needed for the intended application; this usually involves filling the hose with dyed water, pressurizing it, then checking for leaks. Finished assemblies that are not proof tested or have been fabricated based on misleading hose design factors can lead to accidents and injuries. This can result in costly direct expenses, liability insurance claims and downtime – which all negatively impact top line revenue.
End Connections
When selecting hose end connections, consider industry standards, hose types and system specifications. The right hose end connectors keep fluid systems performing optimally, mitigate leakage and corrosion risks, and streamline maintenance tasks.
Choose from a variety of quick-connect couplings for industrial hoses. These reusable couplings have shut-off valves in the plug and socket for minimal fluid loss when disconnecting a hose line. They are typically made of metal, offering more durability than plastic cam-and-groove hose couplings and can withstand harsh environmental conditions.
Select a hose end connector that can withstand harsh physical conditions and high-pressure applications. This durable hose has quick-disconnect fittings on both ends and a tough EPDM rubber cover. Expose it to water, juice, milk, syrup, and more without worrying about the hose deteriorating or becoming brittle. Streamline your inventory with a robust tagging system for hoses and valves throughout the facility. This Swagelok solution simplifies maintenance and reduces downtime caused by unlabeled hoses.
