Hose

An industrial hose is a flexible, reinforced tube used for conveying liquids, solids and gases. A typical industrial hose is dragged, coiled, run over, kinked and subjected to all kinds of wear and tear as well as abuse. Therefore, the application and its environment must be taken into consideration for proper hose selection. Selection of the proper hose and materials will increase hose life, improve performance and ensure safety

Industrial hose is used for three purposes:

To transfer gases, liquids, solids and mixtures of these materials.
As a flexible connector to absorb surges and vibrations.
As a conduit to protect other hoses, pipes and wires.

Three Basic Elements of a Hose

Tube

Its purpose is to handle specific fluids or solids. It is the innermost rubber or plastic component of the hose that must be resistant to the material being conveyed because it is in contact with the material. A variety of compounds can be used depending on the application.

Reinforcement

Its purpose is to withstand a specific amount of working pressure measured in pounds per square inch (psi) or Pascal (Pa) or vacuum (In Hg, inches of mercury). The reinforcement may consist of multiple layers of fabric, yarn or wire placed on top of the tube and referred to as “plies.”

Cover

Its primary purpose is to protect the tube and reinforcement from external factors such as ozone, weather, abrasion and heat. A variety of compounds can be used depending on the application
