Corrosion resistance: 1 main metal soft joint with 304 or 316L stainless steel molding, made of stainless steel or carbon steel joints at both ends of the joint, has good corrosion resistance. Ensure that the sealing. 2 the appearance of the United States: metal soft joint appearance Cheng Liang, permanent bright as new. 3 high voltage: considering many practical work pressure, metal soft joint use of the environment and the use of state, all of the parameters are the result of a careful calculation and experiment, to ensure that the pressure in work safety. The 4 shock proof, dislocation: stainless steel corrugated hydraulic hose manufacturers has good flexibility and compensation displacement characteristics. The 5 construction is good: metal soft joint for the thin wall hydraulic hose fittings , our company mainly engaged in stainless steel metal hose, the overall weight, greatly reduces the load of construction operation and construction time. 6: Cangzhou Zhongwei tube manufacturing many kinds of existing metal soft joint diameter range: DN8-DN4000, other customized according to customer requirements.

The package installation and application range of plastic hose connector

Plastic coated metal hose is mainly used in the production, processing of cable protection. Because the plastic coated metal hydraulic hose manufacturers is light in weight, and flexible with good connecting strength, accessories, electrical properties and oil resistance, water splash and other characteristics, so is widely used in electric power, chemical industry, metallurgy, light industry, machinery and other industries. The package uses plastic hydraulic hose couplings is the protection of wire and cable as well as for insulation, waterproof, and can increase the cable bending appearance.
Although the metal hose can be compressed can be stretched, our company mainly engaged in stainless steel metal hose and other products, but if not in the correct position to install, it will soon break, reduce the service life. Package selection of plastic hose, hose should reference material machine corrosion resistance and corrugated metal hose plastic package nominal diameter, when in use, the first cable wire into the pipe, with corresponding DPJ joint model can be.

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.

Structural classification of fast joint

Both ends of the opening and closing
Do not link: when the mother's ring moved to the other end, stainless stainless steel hydraulic fittings bead automatic roll out, the operation force sub body due to maternal and child body together the valve spring force the valve closed and disconnected, their progeny and parent, instant block fluid flow. Link: when body is inserted into the population, ring back to the original position under the action of a spring, a steel ball rolling lock sub body tightly connected, and parent and progeny promote each other and open the valve, fluid flow, the O ring can completely block the leakage of fluid.
With two open ends
Do not link: when the mother's ring is pushed to the other end, the steel ball automatic roll out, therefore, the sub body is removed; because the child body and parent are no valves, fluid flowing outward. Link: when body is inserted into the maternal, force the spring ring is pushed to the previous location to the steel ball lock, fluid flow, the O type ring to prevent liquid leakage
Single channel opening and closing
Do not link: when the mother's ring moved to the other end, stainless steel metal hydraulic hose adapters automatic roll out, progeny is the valve spring counterforce spring open, the valve can automatically close to block fluid flow. Link: when body is inserted into the maternal side ring, the valve is opened lead to fluid flow, the washer is the force of the spring back to the original position, stainless steel beads will lock to ensure that the child / parent connection, the inside of the washer can completely block the leakage of fluid.

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..

Stainless steel use matters needing attention

1. please do not apply for the fluid fluid outside. 2. do not exceed the maximum limit use of pressure when in use. 3. do not use outside the service temperature range, prevent to cause the sealing material wear or leakage. 4. not to carry out artificial blows, bending, stretching, prevent damage. 5. do not use in metal powder or mixed with sand and dust and other places, to prevent abnormal working or leakage. 6. screw type installation, do not exceed the ma hydraulic hose and fittings ximum tightening torque when installed, to prevent damage. 7. do not use a hose with a crack, prevent leakage or fall off. 8. as for vibration, impact machine will cause lower durability. 9. must be through the use of fluid clean fluid filter. 10. do not remove the quick connector.

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.

Some hydraulic flanges and equipment already comes with hydraulic flanges , also belong to the flange connection. Flanged connections are important pipeline construction. Flanged easy to use, able to withstand greater pressure. In industrial pipe using hydraulic flanges connection is very extensive. Within the family, the pipe diameter is small, but low pressure, invisible hydraulic flanges  connection. If a boiler room or the production site, everywhere flanged pipes and equipment. Often require a high temperature planar hydraulic flanges  temperature sealing member, if the sealant is not a good seal in a separate additional pressure region the influence of pressure, can cause inaccuracies in the production or deformed, which means that the pressure in a separate pressure zone under leakage, thus requiring unscheduled repair.

hydraulic hose assembly Installation

When we conduct bite type fittings installed, the best is to use large-caliber type of connector. Meanwhile, in order to more effectively carry out the installation and in order to effectively reduce the number of factors that we have the labor hydraulic hose fitting . When performing the installation, we first of all is to bite type fittings in the water or the location of the pump outlet opening and stop treatment, the purpose of doing so is to effectively reduce the bite type fittings due to tension or compression caused by impact. Rotary joint in the hydraulic hose couplings and storage process should avoid collision and fall, so as not to damage the interface and internal parts. Installed concentric as possible to ensure the good functioning of the rotary joint. Rotary joint threaded connection during the installation, you should pay attention to the inner and outer tubes are threaded to the direction of rotation of the drum corresponds to the inner and outer tube. No tools are able to achieve a pipeline connected or disconnected joints. Mainly used for air piping, pneumatic tool accessories. There are hydraulic fittings manufacturers  and varied body of material, size and installation of various shapes. Hydraulic hydraulic hose assembly is in addition to the power source, a control section, the application of elements outside the executive body of the hydraulic system, the other part. For example, filters, air-cooled, liquid level gauge, thermometer and more. Commonly used in the press; engineering machinery, dump truck, etc.
