How To Lay Metal Hoses?

Metal hose is a very important part in the industry today. What is the main role it plays? How can it be laid? Let's take a look at our Metal Flexible Hose Manufacturer.

1. The role of metal hose

(1) Relieve the installation stress of the pipeline

In complex pipeline systems, the output is often due to the limitation of the mid-air sentry base, which causes all kinds of loneliness in setting up the work: the formed pipes cannot be loaded; the crane moves westward, bends the stove, and loads them The tube will inevitably produce a part of the cold check. Metal hoses vary according to the diameter of the pipe and the specific conditions of the site. The cold check amount ranges from a few millimeters to tens of millimeters, some of which are hundreds of millimeters. Practice has proved that the larger the amount, the higher the internal stress. These installation stresses left in the piping system are undoubtedly extremely hidden. In a more or less type of engine, a section of air bearing lubricating oil ducts, metal hoses repeatedly broke in the actual turnover, not afraid that the installation stress is too high.

Because the metal hose cannot be bent casually and the internal stress generated by the bending under the principle of rated bending radius is extremely small, it can greatly facilitate the setting and pulling of the operation, and it also plays an important role in the integrity of the piping system. Determined intention to protect.

(2) Steps in filling the empty pipeline

Although the rubber tube has good soft properties and strong anti-fatigue ability, it is also a weak link in terms of pressure resistance, temperature resistance, and aging resistance. After using it for several months, it can't continue to work. The good comprehensive nature of the metal hose is fully reflected in this harvest. In similar industrial fields, in addition to the side pressure and temperature outer ring, there are often harsh specifications such as boredom, corrosion, vibration, search, and impact. Under such movements, metal hoses are used to fill the pipes. Post moves are the most appropriate.

2.Laying of metal hoses

In addition, Metal Flexible Hose needs to be laid when it is used. The requirements for laying are as follows:

(1) The diameter of the metal hose used for the electric wire protection tube with electrical equipment and appliances should not be greater than 1.2m.

(2) Metal hoses should be laid in dry places that are not susceptible to mechanical damage.

(3) Metal hoses must not be buried directly in the ground or concrete.

(4) Metal hoses should not be untwisted or loose.

(5) There should be no joints in the middle of metal hoses.

(6) When connecting metal hoses to equipment and appliances, special joints shall be used.

(7) The connection of metal hoses should be sealed reliably.

(8) The radius of curvature of the metal hose installation shall not be less than 6 times the outer diameter of the hose.

(9) The distance between the fixed points of the metal hose installation should not be greater than 1m. The distance between the tube card and the terminal and the midpoint of the elbow should be 300mm.

(10) The joints of liquid-proof metal hoses shall be well sealed.

(11) When metal hoses are used in special places such as damp, liquid-proof metal hoses with non-metallic sheaths and supporting connecting devices should be used, and their sheaths should be flame-retardant treated.

(12) Metal hoses shall be reliably grounded and shall not be used as ground conductors for electrical equipment.
