Construction of Flexible Hoses
Flexible Hoses.
Flexible hoses are used to transfer different types of fluids such as:
diesel or petrol,
hydraulic oil,
high-pressure compressed air
drilled cutting and,
water and drilling fluids.
Sometimes the fluids inside the hoses are under very high pressure and sometimes they are under low pressure but in all cases, a leaking or a burst hose can cause damage to equipment and serious injury or even death to a person who is close to the burst hose.
Proper inspection of all flexible hoses is therefore an extremely important part of your pre-start inspection procedures and in order to properly inspect a hose you need to understand how hoses are constructed.
