Industrial hoses are designed to withstand extreme pressures, temperatures, and chemical attacks. They are constructed with a flexible rubber outer sheath reinforced with braided fabric or metal sheath. The fittings are rugged and heavy-duty. Different types of industrial hoses face high pressure, extreme temperatures, mechanical stress, and chemical attack. They are reinforced in different ways, including stainless steel or brass braided sleeves and helical stainless steel coils. The fittings are crimped onto the pipe using pressure-resistant collars.
An industrial hose is a hose specifically designed to safely withstand extreme pressures or temperatures and resist attack by caustic or abrasive chemicals associated with industrial processes. Industrial hoses can consist of loose lengths or prefabricated modular units that include application-specific fittings. These hoses are typically constructed with a flexible chemical, heat, and lubricant resistant rubber outer sheath reinforced at various points with a braided fabric or metal sheath. The union between the hose and fittings is also designed to withstand high pressures, and the fittings themselves are typically rugged, heavy-duty variants. Industrial hoses are generally used in hydraulic, pneumatic, high pressure lubrication and chemical processes.
Hoses intended for use in industrial processes generally have to contend with four factors that the common garden hose does not have. These are high pressure, extreme temperatures, mechanical stress and chemical attack. Some types of industrial hoses face most if not all of the above as part of their normal operating regimes. These four aggressive environmental factors are counteracted in different ways and can be applied separately or collectively depending on the end use of the pipes.
High pressure industrial hose intended for use on hydraulic and pneumatic systems is typically reinforced in a number of ways to withstand the high operating pressures. Moderate pressure system hoses can have no more than a simple twine mesh laminated into the rubber of the hose to add extra reinforcement. Those intended for use on high pressure systems will have one or more stainless steel or brass braided sleeves included in the rubber or along the outside of the hose. Some high pressure hoses have helical stainless steel coils included in their construction to serve the same purpose. All of these additional elements physically strengthen the pipes against the expansion stresses of transporting high pressure fluids and gases.
The braids and spiral sleeves also protect the hoses from mechanical stresses such as pinching, rubbing and impact. The high and low temperatures are contrasted in the chemical composition of the pipe material itself. The inclusion of silicone compounds and polymers greatly increases the amount of extreme heat or cold the hose rubber can withstand before it starts to crack. Lubricant and chemical resistance is built into industrial hose in the same way with specially formulated rubber compounds used in the manufacturing of the hose itself. These compounds resist attack by acidic and alkaline media as well as degradation by hydraulic and lubricating oils.
The rugged nature of industrial tubing extends to the fittings used to terminate them. Many types of industrial hose are available in pre-manufactured lengths that include fittings appropriate for the application. These fittings are usually of the heavy duty type and are crimped onto the pipe using pressure resistant collars. These hoses are typically used on specific machines and processes and are custom made to be of the correct length, rating and fitting type off the shelf.
