What is a rubber hose?

by | Dec 10, 2021 | Application study

 

A rubber hose is a kind of hollow cylindrical tube which is designed to carry fluids overland. They are often used in water or other liquid environments to carry air or other gases or they are used in air or other gaseous environments to carry liquids.

Rubber hoses are used for a wide variety of industrial purposes. The hoses are manufactured via extrusion process. This function of the hose sets the key requirements for the rubber used in hoses.

The requirements for rubber in hoses are diverse, depending on the hose type, the product carried and requirements for filler layers and covers. Any hose can have more than one rubber compound type depending on its construction, specially formulated to give the required properties for the layer. One essential factor in rubber hose is to achieve very high levels of adhesion to ensure maximum resistance to fatigue. The key properties for the hose are oil or fluid resistance, high resistance to aromatics, temperature resistance, fatigue resistance and ozone resistance.

  • Oil or fuel etc.

Industrial applications for rubber hoses:

  • Fuel Hose: Fuel hoses are required to have extremely low permeability to fuel in order to regulate and lower hydrocarbon emissions. Mixed fuels like ethanol, methanol etc. require hoses with high resistance to polar solvents. Adding carbon blacks to rubber hoses reduces both permeability of gasoline and swelling of solvents.
  • Radiator Hose: Radiator hoses need to be resistant to coolants at elevated temperatures.
  • Industrial use Hose: There are various types of applications of industrial hoses, including water and steam hoses, air hoses, oil and petroleum hoses, refrigerant hoses, and chemical hoses. Here also, strength and resistance to solvents and chemicals are key requirements.
  • Fire Service: Fire hoses are one of the most recognized hose pipe in industrial usage as they are largely applied in Fire stations and Fire Brigades. The inside of the hose is composed with water resistant rubber compound suitable for the intended use. The cover is also made from rubber which gives outstanding resistance to heat and abrasion and can be stored easily due to it’s flexible properties.
  • Garden Hose: This is used to water plants in a garden or lawn or to carry water to a sprinkler for the same purpose.
  • Air hoses: These hoses are used in underwater diving to carry air from the surface or from air tanks.
  • Automotive hoses: These are used in automobiles to move fluids around for use in lubrication or cooling and in hydraulics.
  • Mining hoses: Used in the mining environment. The different colours of the hoses is usually an indication of the type of fluid or gas carried.
