Rubber pipe refers to the pipe for gas transportation, which is often used in gas welding, gas cutting, various gas protection welding, plasma arc welding and cutting. There are two kinds of rubber pipes for welding, according to the national standard blue pipe for oxygen pipe, the use of pressure is 1.5MPa; The red tube or black tube is an acetylene tube, and the allowable pressure is 0.5 ~ I.mpa.

The characteristics of rubber tube are physiological inertia, ultraviolet resistance, ozone resistance, high and low temperature (-80 to 300 degrees), high transparency, strong resilience, compression resistance without deformation, oil resistance, stamping resistance, acid and alkali resistance, wear resistance, flame resistance, voltage resistance, conductivity and other properties.

1. Do not let the high-pressure hose twist during installation, otherwise the hydraulic hose will be damaged or the joint will relax.

2, Install high-pressure rubber hose between the objects, leaving a certain space to avoid friction between the high-pressure rubber hose and the object during the operation. If not, try to get some protection.

3, the hose and hose assembly should not be used in excess of the design working pressure (including impact pressure).

4, the hose and hose assembly delivered by the medium temperature under normal circumstances, should not exceed -40℃-+120℃, otherwise it will reduce the service life.

5, the hose and hose assembly should not be used less than the bending radius of the hose, to avoid bending or bending near the pipe joint, otherwise it will hinder the hydraulic transmission and delivery of materials or damage the hose assembly.

6, hose and hose assembly, should not be used in the state of torsion.

7. When the temperature rise of the hydraulic system is too high in operation, the high pressure tubing should be checked in time, and the necessary cooling measures should be taken in continuous operation.

8. When the bending radius of the hydraulic hose is too small, right-angle joints are usually used to avoid sharp bending and distortion of the hose.

9, exceed the service period or storage period of the hose and hose assembly to be tested and identified before continuing to use.

In summary, it is the relevant information about the precautions for the use of rubber tubes that is introduced for you, and I hope that these can make you understand. As long as you pay more attention to these matters, it will be used for a longer time.
