The existence of stainless steel metal hose industry problems

1 the cost of rising prices. Iron and steel as the main raw material of stainless steel metal hydraulic hose adapters production has entered the price open and transparent small profits era, rising steel prices will push the stainless steel metal hose production cost;
The brand is poor in China 2 stainless steel metal hose connector industry, international competitiveness is weak. As a result of industrial concentration is low, backward technology, low price competition can not be avoided, China stainless steel metal hose is such a huge market has no real sense of "famous brand on the international";
3 fierce competition constantly eliminated a small stainless steel metal hose enterprise.
4 R & D strength is weak, insufficient capital investment. The technology progress of our country still stays in the overseas in twentieth Century 80 time, although it is a large number of the introduction of advanced technology and production lines, but the basic support for the technology digestion and absorption of the lack of hardware and software.
5 practical technology brain drain. At present, although China has engaged in research work in some colleges and universities, a lot of ethical research, patent papers have a very high level, but combined with production practice is not close, the theory into the finished product ability is poor.

Hydraulic tube fittings can not be used to replace ordinary dedicated connector

Hydraulic tube fittings in the hydraulic system, the connecting member and the pressure tubing pressure tubing between. Hydraulic tube fittings can not be used to replace ordinary dedicated connector, because the hydraulic are can withstand a lot of stress. In the hydraulic system, either a metal hydraulic tube fittings, hoses or fittings, are prone to leakage problems. For card sets of pipe joints, mostly due to the pipeline by a hydraulic tube fittings  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 Hydraulic tube fittings tube hydraulic tube fitting, 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. For use oil sheet, wool felt, soft steel board, combination gasket sealant joints or pipe leaks, no matter what the material is, you should first check the seals for damage, deformation, aging and rough through the large, etc. and then take the appropriate measures.

How to buy and use metal hose

Metal hydraulic hose manufacturers occupied in modern industry's position was certain. However, if the selection is not correct, the use of unreasonable or not installed properly, could not get ideal effect, even caused serious economic losses. Therefore, the engineering design personnel, operation and repair personnel, all kinds of metal hose connector on the proper use of knowledge must have a basic understanding of.
The selection of the length of
"Hose, can be short or long". However, metal hose working conditions often due to determine the length of inappropriate, caused by this or that problem. For example: metal hose compensator used for too long, will produce the instability; the pump inlet, pump outlet used metal hose is too long, will produce the additional vibration; metal hose is too long for the pipeline system, will produce large fluid resistance etc.. Of course, put them to shorten the length of some, there can avoid these problems. However, blindly shorten. It is impossible to achieve compensation, vibration, noise elimination purposes. At the same time, the superiority of the metal hose in other aspects are not fully reflect. So, to determine the metal hose length is a very important work.
(1) as a metal hose compensator for, its length depends on the diameter size. The following basic principles: the calculation of diameter less than or equal to 250 mm, diameter less than or equal to 400 mm in diameter, that is less than or equal to 1000 mm,: in the pipeline system, if the compensation of a compensator is not enough, you can use two, three....... If by spatial location conditions, compensator may not install a plurality of, can choose a duplex structure. But the formula (7. (7, 1). (7, 2). 3) principle shall not violate.
(2) for the vibration, the elimination of the pump inlet, pump outlet pipe with noise, depends on the length of the path size, i.e. diameter less than or equal to 100 mm, formula (7. 1) ~ (7. 4), the L compensator or metallic flexible hose length; for the compensator or metal hose diameter.
(3) metal hose angular displacement, length depends on the actual bending radius and displacement angle. That is, (4) metal hose of lateral displacement, length depends on the actual bending and transverse displacement radius size. That is: cut the line refers to the time of the lateral displacement of the metal hose, transitional stage two of the same radius, different direction bending pipe. The calculation, according to the times of the diameter generally consider the length of.
(5) in the bending state, parallel longitudinal movement of the metal hose length depends on the actual bending radius and longitudinal movement quantity. That (6) in the bending state, the parallel sections of lateral movement of the metal hose length depends on the actual bending radius and the transverse moving volume size). That is the formula (7. 5) ~ (7. 2), and L is a metal hose flexible segment length; for metal hose diameter; displacement angle; Y is a single horizontal displacement; T is the total displacement of longitudinal or transverse quantity.

Advantages Hydraulic flanges are: small size, light weight, good flexibility, easy installation and maintenance, can hydraulic flanges lateral, axial, angular displacement, from the pipes of different heart, not parallel flange installation restrictions, can reduce the structural work pass noise, strong vibration absorption capability. Advantages flange hydraulic flange fittings joints is: when the outside temperature changes, the tube allows free expansion pipeline capacity within telescopic range, locking telescopic amount, to ensure safe operation of the pipeline. Transmission Joint Flange advantage is: can effectively compensate and mitigate pipeline and Blind thrust, but also easy to pump hose connector flange advantage is: has good flexibility and fatigue resistance, making it very easy to absorb various sports deformation cyclic loading, especially the ability to compensate for the large amount of displacement in the piping system.

Hydraulic ferrules cold deformation, flaring, flattening no cracks

Hydraulic ferrules is one of the three parts of the card sets of pipe joints (ferrules, nuts, seamless steel pipe) composed. Hydraulic ferrules working principle is the seamless steel insert card kit, ferrule nut using inconsistent card sets, card kit seamless steel blade evenly cut, form an effective seal. Hydraulic ferrules type straight pipe hydraulic flanges are widely used in oil refining, chemical, oil, gas, food, pharmaceutical, and other instruments. Hydraulic ferrules high accuracy, good finish, inside and outside the walls of the heat pipe no oxide layer, the hydraulic hose assembly wall of cleanliness is good, pipe withstand high pressure. Hydraulic ferrules cold deformation, flaring, flattening no cracks, deformation and can make a variety of complex mechanical processing. Hydraulic ferrules joints inside and outside the installation need to take over the interface and connection fittings are handling clean. Be sure to take over the mouth of the polished smooth surface can not have glitches and uneven surfaces.

Hydraulic hose

Hydraulic hydraulic hose manufacturers is mainly composed of an inner rubber layer, the adhesive layer, liquid resistance in 2 or 4 or 6 layers of spiral steel wire reinforced layer, cover, the inner layer is putting pressure on the transport medium, the protection of wire is not affected by erosion, outer layer protection wire is not damaged, the steel wire layer is the skeleton material enhancement effect. Hydraulic power transmission or conveyance of water, gas, oil and other high pressure medium, so as to ensure the liquid circulation and transfer the liquid energy. Characteristics of the 1 hydraulic hose adapters adopts special synthetic rubber made with, has excellent oil resistance, heat resistance, aging resistance performance. Closely, combining the 2 pipe body soft, under the pressure of small deformation. The 3 hose has excellent flexibility and fatigue resistance.

Joint metal hose

Stainless steel metal hose joint effects first was the net sleeve are connected into integration, and the corrugated pipe, joint is also a metal hydraulic hose assembly and metal hose or other fittings, equipment connected components. It ensure that the medium in pipeline system in normal operation. Joint data usually with bellows, net sets of data, multiple stainless steel based. In order to decrease production cost, some of the larger diameter metal hydraulic hose fitting in the delivery of corrosion is not strong or non corrosive medium, joint can be used for carbon steel manufacturing; joint metal hose on the corrosive medium task conditions, corresponding measures if the description is adopted, and the medium to avoid the touch, can also choose carbon steel to manufacture. The layout mode of joint generally divided into spiral, flange type and fast type three categories:
1, screw type: diameter 50 mm below the joint metal hose, high pressure in an operation under the condition of multi thread based on, when tightening the threaded in the future, close cooperation of two joints on the inner and outer taper surface, complete seal. The cone angle is usually 60 degrees, 74 degrees is also useful. The layout, good sealing, but the device when necessary ensure the concentricity of the two docking part. In order to deal with engineering practice is often seen repeated disassembly and assembly and not easy to be concentric and other issues, will also be described as conical and ball head joint cooperation.
2, the flange disc: diameter for the joint metal hose is more than 25 mm, often in an operation under pressure, with flanged mainly, which cooperate to mortise way seal. Along the radial change, also capable of sliding along the axial direction of the looper flange connection of two bodies in the fastening bolt tension effect. The layout of the sealing function is good, but the processing difficulty, simple sealing surface bumps. Special occasions quick release in need, can cut the fastening bolt through hole, made quick detachable flange.
3, express: diameter for the joints of various metal hose 100 mm below the condition of using requirements, in rapid loading and unloading, usually choose fast type. O shaped it commonly used fluorine plastic or special rubber seal ring seal. When the handle to move the view must be in the future, the equivalent of multiple threads of fingers locked; the O shaped sealing ring is pressed more tightly, the sealing function is better. The layout in the fire, war and other necessary for fast loading and unloading is most suitable for the occasion. In seconds, not to be matched with any special tools, can butt or open a group of joint.

The characteristics of corrugated metal hose

1, recommended every wave maximum allowable amount of expansion: full height delta alpha = + 24mm semi delta alpha = + 12mm.

2, the ash blocking plate: pipe on the air duct or less dust may not apply to dust, flue ash blocking plate should be adopted.

3, as the number of wave section reducing bellows, should consider the cold 50%.

4, the standard semi corrugated metal hydraulic hose assembly is suitable for the cross-sectional area smaller than one side less than 1.5m but higher than 0.6mm occasions of 4.6 square meters and gas duct dimensions in. Standard high corrugated metal hose suitable for duct smoke all.

Corrugated metal hydraulic hose couplings has good flexibility, fatigue resistance, high pressure resistance, high and low temperature resistance, corrosion resistance and many other features, it is relative to other hoses (rubber and plastics hoses) life is much higher, the comprehensive economic benefit so it has higher. With the development of modern industry, the high temperature resistant, resistant to high pressure corrugated hoses demand you also more and more.

Hose applicable scope: the need for fully flexible pipeline to prevent the vibration of the premises, piping, suitable for both steam, gas, air, oil, petroleum, chemicals etc..
