Stainless steel metal hose to do what performance test

Stainless steel metal metric hydraulic hose fittings with flexibility, corrosion resistance, high temperature resistance, tensile resistance etc.. To achieve such a sophisticated quality must have strict production processes control, but also the need for strict performance testing to ensure quality. The following sea island for you under the stainless steel metal hydraulic hose fittings must be what strict performance test before they leave the factory.
1 pressure test
Pressure test is also called the strength test, which belongs to the safety performance index test. The test pressure is 1.5 times the nominal pressure, test pressure medium for pure water, the chloride ion content should not exceed 25ppm. Each product must withstand voltage test. By using manual or electric pressure test pump pressure, pressure observation usually available 1.5--4 times of test pressure range of level 1.5 or above or equivalent efficacy of pressure gauge, pressure test instrument. During the experiment, the specimen is placed at one end of the straight hose, install the plug with the exhaust valve, the other end is connected with the pressure test pump outlet pipe, the water will be injected into the tube, exhaust air, exhaust valve closed, and then slowly increased pressure test pressure to the specified value, holding pressure 5min, check the sample status, failure form has no leakage, damage to parts such as abnormal. Requirements for qualified product does not allow failure form of sign of leakage or damage to parts such as abnormal.
2 air tightness test
Air tightness test is also a safety index test, each require a manufactured products are to be tested. Air tightness test in the nominal pressure, qualified products does not allow leakage phenomenon, air tightness test can be carried out in the pressure test qualified rear. Experiments using dry, clean air, or the need to use nitrogen or other protective gas as the test medium. The pressure device can adopt the compressor, air pressure generating device, the cylinder or cylinder group. Pressure observation usually adopts 1.5 grade above or equivalent measurement precision pressure gauge pressure testing instrument, with a full set of test equipment groove. Test specimen is arranged on one end of the hose plug, and the other end of the air outlet is connected with the pressurizing device, gas pressure equal to the nominal pressure, the specimen immersed in the water tank, remove the adsorbed on the net sleeve on the bubble, when the air pressure is stable after the pressure 10min check for gas leakage test piece.
Stainless steel metal hose is commonly used now do all sorts of equipment signal wire, wire and cable transmission, optical fiber protection, it and people's work life. If the product quality problems, will bring some loss. So rigorous performance testing is indispensable, and must be strictly implemented once found the product flaw, should be dealt with immediately, must not hold fluky mentality.

Stainless steel corrugated pipe application field is not common

In the general understanding of everybody, stainless steel corrugated hydraulic pipe fittings used for pipeline construction, gas pipeline, water pipeline and so on, but some places are not common, also has the application of stainless stainless steel hydraulic fittings corrugated pipe. Electric power, chemical industry, automobile, can imagine the application of stainless steel corrugated pipe in these areas?
1, the electric power engineering is also used. Gas turbine power generation equipment, superheater and other requirements of high temperature resistant and corrosion resistant components are also involved in gang stainless application of corrugated pipe.
2, for the field of automobile engineering. Stainless steel corrugated pipe is mainly used for automobile engine exhaust device, such as exhaust valve, spark plugs, pipes, exhaust purifier etc..

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.

Hydraulic fast joint prevention leakage

In the hydraulic system, whether it is a metal pipe joint, or hydraulic hose manufacturers connectors, are prone to leakage problem. The sleeve type pipe joint, mostly because of pipeline subjected to external force or large impact force, the card sets loose or pipe end deformation caused by leakage, you should check the card sleeve is losing a round, cutting edge has no defect, tube end is intact and the card sleeve nut tightening degree, also eliminate the pipeline external force. The flared fitting, mostly because of the flaring over, does not meet the quality requirements or repeated disassembly, causing the flaring deformation or crack causing leakage, the front end truncated re expanding. If the use of male and female cone top pressure seal, the leakage is due mostly to the two conical surface is damaged, can be used for grinding the conical surface grinding.
In some "from" ring on end face or the outer diameter sealing occasions, the leakage reason has the following kinds: "from" ring aging or deformation caused by leakage; "from" ring assembly is not in place, the two plane connection pressure uneven or "from" ring was cut from causing leakage; "" ring not compacting, elastic deformation caused by lack of leakage; "from" ring rabbet groove deep caused leakage. In this regard, the need to re select the identical diameter and section of coarse "from" ring, can also be provided with a sealing plane rabbet groove cutting or grinding, in order to reduce the rabbet groove depth, so that the "from" ring have enough elastic deformation (compression in general should be between 0.35-0.65mm).
For the pipe joint oil resistant rubber, wool, mild steel board, combined sealing washer or sealant leak, whatever the material, should first check the seal is damaged, and the rough situation such as deformation, aging, and then take appropriate measures.

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.
