Hose fittings mainly by the bellows, nets and connector components

Hose fittings are modern industrial piping in a high-quality flexible pipeline.  Hose fittings mainly by the bellows, nets and connector components. Hose fittings of the tube is a thin spiral or circular stainless steel bellows, bellows outer nets, are made ??of stainless steel wire or woven according to certain parameters. Metal hose fittings are modern hydraulic hose fittings  piping in a high-quality flexible pipeline. It mainly consists of bellows, nets and connector components. Its inner tube is a thin spiral or circular stainless steel bellows, bellows outer nets, are made ??of stainless steel wire or woven according to certain parameters. Both ends of the hose hydraulic hose fitting or flange or flange joints with the customer mating pipe. Bellows hose is extremely thin-walled seamless or welded stainless steel pipe after all machining precision plastic molding. Since the elastic properties of the corrugated pipe determines the contour of the hose has good flexibility and fatigue resistance, it is easy to absorb the deformation of the movement cycle of the load, in particular the ability to compensate for the large amount of displacement in the pipeline system. Media Visualization (mediated visual), process automation.

The performance index of corrugated metal pipe

Rigidity
Load the stainless steel metal hose or other elastic elements demand unit displacement value is called an element stiffness, usually with K show. If the elastic properties of error linear element, the stiffness is no longer constant, but with the increase of the load change.
Nominal rigidity
The elastic element portray accounting is presented when the stiffness is called the nominal (or additional) stiffness. The measured it with the element stiffness error, especially the elastic element with nonlinear elastic characteristics. Nominal rigidity is representative of the curve where a little stiffness, should carefully consider. Generally speaking, the nominal rigidity the best not to directly select depicting the accounting value, but should use the product by modifying the value after the prototype test.
Stiffness tolerances
A group of elastic element stiffness promise of the slack test scale. For the same batch of elastic elements, each element stiffness are not the same, there is a slack scale. In order to ensure the use of performance elements, it is necessary to have a limit on the stiffness and laxity scale. On the elastic sensitive element, the stiffness of the tolerance demand restricted within the nominal value of +/-5%; usually works with the corrugated tube elastic element stiffness tolerances can be limited within the +/-50%.
Sensitivity
Metal corrugated hydraulic pipe fittings and other elastic element to accept the displacement quantity of unit load when the member is called element sensitivity. Rigidity and sensitivity are the main function parameters of corrugated hydraulic fitting adapters and other elastic elements, but they are two different ways to use that same characteristics. On different occasions, in order to facilitate the analysis of the problems, can choose between any kind of parameter.
Useful area
The elastic element on the completion of the pressure force or power of a pressure transducer, and an important function of the target area is useful. Useful area refers to the elastic element in the unit pressure effect, when the zero displacement can transform into a concentrated force size.
The use of life
The elastic element as there are two kinds of situation; one is operating in the load and displacement bound, and adhere to the load and displacement remains unchanged or rarely change, called static operation; another application is constantly cycle load and displacement reciprocating replacement change. The element is in the circulation work condition. Because the work condition is not the same, the damage of components or in the form of failure is not the same. The appearance of the elastic sensitive element operation in the elastic range, basically in the static operation condition, the use of life is very long, usually reaching tens of thousands of times to hundreds of thousands of times. Corrugated tube components used in the project, sometimes work in the elastic-plastic scale or alternating stress status, life as long as hundreds of dry time. Elements necessary given allowable operation life in cyclic operation, rule cycles, time and frequency.
Additional elastic component is the component life painted set expectations with life, demand during this period element does not promise appears tired, damage or failure of representation.

Its inner tube is a thin spiral or circular Hydraulic hose fittings bellows, bellows outer nets, are made ​​of stainless steel wire or woven according to certain parameters. Both ends of the hydraulic hose fittings connector or flange or flange joints with the customer mating pipe. Bellows hose is extremely thin-walled seamless or welded stainless steel pipe after all machining precision plastic molding. Since the elastic properties of the corrugated pipe determines the contour of the hose has good flexibility and fatigue resistance, it is easy to absorb the deformation of the movement cycle of the load, in particular the ability to compensate for the large amount of displacement in the pipeline system.

Hose fittings In the hydraulic system, the connecting member and the pressure tubing pressure tubing between. hose fittings classification: hose fittings, high pressure ball valve, sleeve type pipe fittings, welded pipe fittings, high pressure hose, transition type fittings, bite type fittings, tee pipe fittings, non-standard pipe fittings and so on. In the Hydraulic hose fittings system, both the metal pipe fitting, hose fitting, or are prone to leakage problems. For card sets of pipe joints, mostly due to the pipeline by a larger force or impact, so that the card sleeve loose or pipe end surface deformation caused by leaks, you should check whether the card sets out of round, edge or without defects, whether the pipe ends in good condition and the extent of hose fitting ferrule nut, but also eliminate the pipeline force. For flared fittings, mostly due to excessive flaring, substandard quality requirements or repeatedly demolished, resulting in flaring deformation or cracks caused by leaks, then you can be re-flared front amputated. If you use a male and female cone top pressure seal, which is mostly due to the two cone leak damage, is available on the cone grinders for grinding. Install hose fittings Note: Pipeline in mobile or stationary, and are not excessively bend, nor bend at the root, the pipeline is moved to the extreme position when not pulled too tight, should be more relaxed, try to avoid torsional deformation pipeline

hydraulic hose fitting installation and leak prevention

hydraulic hose fitting, connecting parts and pressure tubing pressure tubing between. hydraulic hose fitting pressure is great amazing, hydraulic hose fitting oil pipe suddenly burst impact is great. When hydraulic hose fittings  installed, according to the required length by sawing or special pipe cutting machines and other equipment off the tube, and definitely not with a melting off (such as flame cutting) or wheel cutting; removing the pipe ends and outside round burrs, metal chips and dirt; remove pipe fittings the anti-rust agents dirt; while also ensuring tube roundness; in the Hydraulic hose fittings , whether it is metal fittings, or hose fittings, are prone to leakage problems. For card sets of pipe joints, mostly due to the pipeline by a larger force or impact, so that the card sleeve loose or pipe end surface deformation caused by leaks, you should check whether the card sets out of round, edge or without defects, whether the pipe ends in good condition and the extent of compression ferrule nut, but also eliminate the pipeline force. For flared fittings, mostly due to excessive flaring, substandard quality requirements or repeatedly demolished, resulting in flaring deformation or cracks caused by leaks, then you can be re-flared front amputated.

hose fitting connectors installation method

Hydraulic hose fitting connectors installation method 1, under the appropriate length of seamless steel saws, removing burrs at the port. Tube end to the vertical axis. If you need to bend the tube, from the end face of the tube to bend parts of the line segment length can not be less than three times the length of the nut. 2, put a condom on a nut and seamless steel pipe. Note the direction of the nut and hydraulic hose fittings , not installed backwards. 3, in the pre-assembled connector body threads and put the card Lubricate the tube into the connector body,  Tighten the nuts by hand. 4, tighten the nut until the sleeve stuck pipe, this turning point tightening torque can be increased by feel  5, after reaching the pressure points, and then hydraulic pipe fittings  the compression nut half circle. 6, the pre-assembled connector body removed, embedded Check card sets blade edges, protrusions visible space must be filled with ferrule end face. Card sets can be slightly rotated, but not axial passage. 7, the final installation, threaded greased the actual installation of the connector body, the compression nut screwed to the increase associated with the tightening force can be felt far. Then hydraulic adaptor fittings laps installed. Fittings installation instructions Inside and outside to take over the interface when installing fittings need to connect with the fittings are handled clean, take over the mouth must be polished smooth surface can not have glitches and uneven surfaces. And take over the site and fittings embedded bending phenomenon should not have, or will cause the connection fittings and steel pipe leakage phenomenon. Pipe fittings at both ends of the connection tube best uniform material, which can effectively prevent leakage. After embedding steel fittings body began efforts to tighten ferrule efforts should not be too large, should be gradual stop screwing the threaded sleeve or two-thirds of the tail, there is a wrench in the card sleeve fastening click.
