Model length and connection mode of stainless steel metal hose
Model length and connection mode of stainless steel metal hose
Stainless steel metal hose is used by many companies or construction teams. It is because he has many advantages, which can provide people with much convenience. First, he has good softness and can bend freely with the angle of construction needs. Second, it has corrosion resistance, because his material is stainless steel. So even in the ground, or in the water, the stainless steel hose will not be corroded. Besides, he can endure high temperature and wear resistance, which prolongs his service life. Besides, his tensile performance is not easy to break and deform, and it also brings great help to construction. A hose three functions described as follows: first, to reduce the pipeline installation stress in complex piping systems, often because of space constraints, resulting in difficulties on installation: forming pipe is not up; and bending over, in turn, just installed pipes will inevitably produce local cold correction. Depending on the diameter of the tube and the actual situation in the field, the cold correction amount is from several millimeters to dozens of millimeters, and some are hundreds of millimeters. It has been proved that the greater the amount, the higher the internal stress, and the residual stress in the pipeline system, which is undoubtedly a great hidden interest. One type of bearing lubricating oil pipe in a certain type of engine has many faults in actual operation, which is caused by excessive installation stress. Because the metal hose can bend at any time and the internal stress generated by bending under the condition of rated bending radius is very small, it can bring great convenience to the installation work, and it also plays a certain role in ensuring the safe operation of the pipeline system. This is the main reason that some piping systems must use a metal hose. Two. The movable cylinder on the vulcanizing machine will move upwards and downwards due to the need of loading and unloading die. After the reciprocating movement of the copper snake tube, the fatigue fracture will occur, although it can continue to be used after repair, but the parking repair will cause time loss. Although the rubber tube has good softness and strong fatigue resistance, it is also a weak link in pressure, temperature resistance and aging resistance. After several months of use, it can no longer continue.
The metal hose of stainless steel metal hose is an important connecting component in engineering technology, which is formed by the combination of corrugated flexible pipe, net sleeve and joint. In all kinds of gas and liquid pipeline system, length, temperature, position and angle compensation system as the compensation element, a sealing element and connecting element and damping element, its characteristics are: corrosion resistance, high temperature resistance, low temperature (-196 DEG -+420 DEG), light weight, small volume and good flexibility. It is used in aerospace, petrochemical, mine electronics, machinery shipbuilding, light textile electronics, energy building and other fields.
Type length and connection mode of stainless steel hose: according to user's requirements. Application: metal hose has good flexibility and temperature resistance, pressure resistance and corrosion resistance. It is suitable for steam, water, oil and all kinds of industrial gases, Yao products and other media delivery. It plays an important role in the movement of the pipeline system, the absorption of thermal expansion and the absorption of vibration. The model length and connection mode are required by the user. The stainless steel pressure resistant metal hose is made of stainless steel bellows, which is made up of one or more layers of steel wire or steel belt net sleeves. The two ends are connected with flanges, which are used for conveying various kinds of flexible components. The characteristics are: corrosion resistance, high temperature resistance, low temperature weight, light weight, small volume and good softness. Widely used in aviation, aerospace, petroleum, chemical, metallurgical, power, paper, wood, textile, construction, medical Yao, food, yancao, transportation and other industries. Stainless steel metal hose (metal bellows) division of production of stainless steel metal hose, stainless steel pipe, stainless steel corrugated metal soft joints, including stainless steel wire braided hose, metal bellows, stainless steel fluid conveying pump damping hose, stainless steel fire hose, stainless steel bellows, mechanical gas stainless steel bellows fully meet the domestic industry standard. Stainless steel wire mesh sleeve in the connection of stainless steel metal hose is mainly to protect the bellows and withstand the pressure of the medium in the bellows (mainly axial force). The net covers are coated on the outside of the bellows, and the two ends are welded with the bellows and end rings and joints. (1) weld caused due to pull off screen set of welding quality, the bellows, ring and steel wire net wire in part caused by three-in-one during welding weld (burning or welding on the end). This metal hose into the pipeline after the wire due to uneven stress, in the medium under pressure, weld wire at first pull off, so that the whole set of wire pulling, resulting in bellows bulge failure risk. In order to prevent this situation from happening, the welding quality should be improved. The water pressure and air tightness test should be carried out before the hose is out of the factory. (2) caused by improper installation, pull off the hose wire in the installation process, stainless steel metal hose due to improper installation, or under high pressure, the hose will be stretched and twisted, distorted or when the tensile stress produced beyond metal hose wire net sets the ultimate strength, will make the net three-in-one welding hose or other parts of the net broken, so that the bellows bulge tensile failure, stainless steel metal hose caused by medium leakage, therefore should require the design and selection of accurate, correct installation.
