Tubing. Tube Connectors and Flexible Hose.
The various units of a hydraulic system are connected with some form of tubing or flexible hose.
Tubes are joined by means of tube connectors, usually of the same material.
Tubing. - Some of the factors governing the selection of tubing are corrosion, temperature, weight, mechanical strains, abuse and pressures. Because of its light weight, aluminum-alloy tubing and fittings are used wherever possible. Fittings are designed to withstand the bursting pressure that the tube of maximum wall thickness will withstand, assuming that the tube and fittings are of similar materials. For general high-pressure installations steel tubes and fittings are recommended. Flexible Hose. - Flexible Hose is used to connect hydraulic units between stationary and moving parts. Hoses are made up of varying layers of synthetic rubber, fabric and wire braid. In installing flexible hose care must be taken that the hose is free from twists. Under pressure a twist will rotate the hose and loosen the connection, causing failure.
3. Answer the questions :
Are the various units of a hydraulic system connected with flexible hose?
How are the tubes joined of tube connectors?
What are the factors of governing selection?
Where are the aluminum-alloy tubing used?
Fitting are designed to withstand the bursting pressure, are not they?
Is flexible hose used to connect hydraulic units?
What materials are hoses made up of?
