What are the different types of fluid lines?
The three types of lines used in fluid power systems are
pipe (rigid), tubing (semirigid), and hose (flexible)
. A number of factors are considered when the type of line is selected for a particular fluid system.
What is aircraft flexible hose?
Flexible hose is
used in aircraft fluid systems to connect moving parts with stationary parts in locations subject to vibration
or where a great amount of flexibility is needed. It can also serve as a connector in metal tubing systems.
What is low pressure hose?
The tight grip remains constant
under pressure up to 250 psi
. … Hose is designed for operation in temperatures from -20° to 180° F.
What metal is flexible pipes?
Flexible metal hose is fabricated from a variety of corrosion-resistant metals, including
stainless steel, aluminum alloys, and corrugated bronze
. In the case of bronze hoses, the bronze tube is typically encased in a braided metal shielding, which provides added resistance to wear and pressure.

How are flexible fluid lines measured?
Tubing size is measured
on the outside diameter of the tube
. All sizes are available in a variety of wall thicknesses. The application and use of tubing, (material, diameter and maximum pressure) will determine the wall thickness of the tubing used. Sizes range from 1⁄8 to 2 in.
What is a fluid line?
(General Physics) a substance, such as a liquid or gas,
that can flow
, has no fixed shape, and offers little resistance to an external stress. adj.
What is a fitting in aircraft?
Aircraft fluid lines are usually made
of metal tubing or flexible hose
. They are widely used in aircraft for fuel, oil, coolant, oxygen, instrument, and hydraulic lines. … Flexible hose is generally used with moving parts or where the hose is subject to considerable vibration.
What are flexible hoses made of?
The fabric material used to make flexible hoses is usually
coated in plastic or rubber compounds
, the most prominent examples being neoprene and PVC. This coating gives the hoses an improved level of physical durability and even protection against harsh chemicals and elevated temperatures.
Why the flexible hoses are used in aircraft fluid system?
Flexible hose is used in aircraft fluid systems
to connect moving parts with stationary parts in locations subject to vibration or where a great amount of flexibility is needed
. It can also serve as a connector in metal tubing systems.
How are aircraft flexible hoses identified?
Hose Identification
These markings are in contrasting colored letters and numerals which indicate the natural lay (no twist) of the hose and
are repeated at intervals of not more than 9 inches along the length of the hose
.
