A403 WP304 stainless steel metal hose with flanges at both ends of the wire and cable protection tube
Metal hose is an important component in the connecting pipeline of modern industrial equipment. Metal hoses are used as wire and cable protection tubes for wires, cables, automatic instrument signals and civilian shower hoses, with specifications ranging from 3mm to 150mm. Small-caliber metal hoses (inner diameter 3mm-25mm) are mainly used for the protection of sensing lines of precision optical scales and industrial sensor lines.
Pipeline installation stress
In complex piping systems, there are often various difficulties in installation due to the constraints of the space and location conditions: the formed pipe cannot be installed; bending, straight, and improvising the installed pipe will inevitably produce partial Cold correction. Depending on the pipe diameter and the specific situation of the site, the amount of cold correction ranges from a few millimeters to tens of millimeters, and some up to hundreds of millimeters. Practice has proved that the larger the amount, the higher the internal stress, and these remaining installation stresses in the pipeline system are undoubtedly extremely hidden.
A section of the bearing lubricating oil duct in a certain type of engine has broken accidents many times in actual operation because of excessive installation stress.
Because it can be bent at will and the internal stress generated by bending under the condition of the rated bending radius is extremely small, it can bring great convenience to the installation work and also play a certain role in guaranteeing the safe operation of the pipeline system. This is the main reason why metal hoses must be used in certain piping systems.
Compensation pipeline position
Due to the needs of loading and unloading molds, the movable cylinder on the vulcanizing machine will move upward and downward. After the copper serpentine tube reciprocates for many times, fatigue fracture will occur. Although it can be used after repairing, it will cause time loss for parking repair. Although rubber hose has good soft properties and strong fatigue resistance, it is a weak link in terms of pressure resistance, temperature resistance, and aging resistance. Generally, it cannot continue after a few months of use. The good comprehensive performance of the metal hose is fully reflected here. In general industrial fields, in addition to pressure and temperature, there are often harsh conditions such as fatigue, corrosion, vibration, compression, and impact. Under such circumstances, it is most appropriate to compensate for the positional movement of the pipeline. Of it.
product description
| name | Metal Hose |
| Specification model | DN6-DN30 |
| Material | TP304/304L,TP316/316L,A105 |
| form | Threading hose, corrugated hose, net sleeve hose, thread type, flange type, fast type |
| structure | The metal hose is generally composed of three parts: corrugated pipe, net sleeve and joint. The corrugated pipe is the body of the metal hose, which plays a flexible role; the net sleeve plays the role of strengthening and shielding; the joint plays the role of connection. For different usage requirements, they are connected in different ways: the bellows, the mesh sleeve and the joint are connected in the form of welding, called welding; connected in the form of mechanical clamping, called mechanical clamping, In addition, there is a combination of the above two methods, called hybrid. Metal hose products include oil and suction hoses, steam hoses, sandblasting hoses, acid and alkali suction hoses, food hoses, oxygen blowing hoses and various special-shaped hoses. It is widely used in machinery, chemical, petroleum, metallurgy, food and other industries. What is the pressure range of the pressure-resistant metal hose: The pressure range of the hose is generally PN0.6-32.0Mpa. The highest is 42.0MPa. The metal hose is the main pressure-bearing part of the hose installed in the pressure pipeline, and it also acts as a sheath for the corrugated pipe. According to the pressure in the pipeline and the application site, one or more layers of stainless steel wire or steel belt can be selected Weave. |
| Features | Since the main parts of the hose are made of austenitic stainless steel, it ensures the excellent temperature resistance and corrosion resistance of the hose. The working temperature range of the hose is extremely wide, ranging from -196 to 600 ℃. The hose used The corrosion resistance of the hose can be ensured by selecting the applicable stainless steel grade according to the corrosiveness of the medium passing through the pipeline. 1. The metal hose is made of 1Cr18Ni9Ti stainless steel material, which has strong corrosion resistance. 2. The hose body is a thin-walled stainless steel tube that is hydroformed, which has strong flexibility, flexibility, bending and vibration resistance, and the strengthened protection of the woven mesh sleeve makes it have a higher pressure bearing capacity. 3. The connection at both ends of the hose can also be made into other connection methods besides thread and flange standards, which is convenient for connection and use. 4. This product is not only suitable for matching with rotary joints, but also widely used in flexible connections for conveying a variety of fluid media. Corrosion resistance, high temperature resistance, low temperature resistance (-196℃~+420℃), light weight, small size and good flexibility. It is widely used in aviation, aerospace, petroleum, chemical industry, metallurgy, electric power, papermaking, wood, textile, construction, medicine, food, tobacco, transportation and other industries. 1. Flexible hoses between metal hose pitches, with small bending radius. 2. The metal hose has good flexibility, no blockage or stiffness. 3. The metal hose has a light unit weight and good caliber consistency. 4. The metal hose has good flexibility, repetitive bending and flexibility. 5. The metal hose has good corrosion resistance and high temperature resistance. 6. The metal hose is resistant to rat bites and abrasion, and prevents the internal wires from being abraded. 7. The metal hose has strong bending resistance, tensile resistance and lateral pressure resistance. 8. The metal hose is soft and smooth, easy to install and locate. 9. There are many hose joints for metal hoses, which are easy to connect with equipment. |
installation method
Although the metal hose can be compressed or stretched, if it is not installed in the correct position, it will break quickly and reduce its service life.
The hose can be installed horizontally, vertically or diagonally. The most ideal state is vertical installation. At the same time, it should be avoided near the wheel, and baffles can be installed if necessary.
Generally, metal hoses can be divided into three types of lengths: the first type is the compressed length, which is the length when the hose is compressed to the limit position; the second type is the installation length, which is the middle position of the half of the maximum displacement The length of the hose; the third type is the stretched length, the length of the hose being stretched to the maximum limit.
When installing the hose, the hose should be in the middle position, the so-called installation length. When installed in this position, the hose can have two moving directions when subjected to axial load. Otherwise, if it can only move in one direction, it will affect the strength of the metal hose and reduce its service life.
In the actual installation process, considering that the use of a ruler to measure the length of the hose according to the calculation result before installation may affect production efficiency, some foreign manufacturers install the ruler directly on the hose and cut the ruler after installation.
1. When choosing a metal hose, please choose a metal hose with a loose flange at one end for easy installation.
2. The surface of the metal hose should be protected during electric welding at the construction site to prevent welding slag and arc ignition from burning the metal hose.
3. Twisted installation of metal hose is strictly prohibited.
4. There should be no bending along the root of the metal hose, and no dead bends.
5. The passing medium must not be corrosive to the corrugated pipe material, and the chloride ion content in the medium should be ≤25PPM
6. Strictly install the installation as shown in the correct installation method. (See installation guide)
7. It is strictly forbidden to damage the flange sealing surface mechanically
