Transition joints are widely used in our life, especially in pipeline connection and cable laying, it has become one of the essential tools, especially in the development of new infrastructure plays a vital role. As the most mainstream joint products, I will take you to understand the use of transition joints? What are the problems that need to be paid attention to in the use?

What are the uses of transition joints? What problems need to pay attention to in the use?

　　First, what are the uses of transition joints

　　The current use of over joints is very wide, its main role is to play a role in the two different types of pipeline connection, especially in the field of telecommunications and electricity, its role can be seen. Let's say when the pipe can not be bent due to the reason of the material, then you need to use the excessive joints to connect the two pipes, which can play the effect of bending.

　　Second, the ferry joint precautions

　　Installation of excessive joints in the process, be sure to use the pipeline calibre and transition joints aperture is the same, and in the installation process to do a good job of leakage and corrosion prevention measures. After all, regardless of whether the pipe is used as a cable fibre protection or used to transport liquids and gases bearing channels, sealing is a prerequisite that must be taken into account. At the same time to ensure adequate sealing at the same time, but also do a good job of anti-corrosion treatment.

　　The above is about the excessive joints used and the installation of the problems needing attention to the analysis of the product is now in the power and communications industry, the degree of use is very popular, especially due to the rapid development of new infrastructure, transition joints, the market demand for a substantial increase in the understanding of these issues, in the future use of the product will avoid a lot of unnecessary trouble.

In hydraulic fittings, hose fittings are fittings that are clamped to the ends of hydraulic hoses. The connection of hose fittings to component ports usually requires transition fittings, and hydraulic transition fittings act between hard fittings and ported members during the transition process, or directly as part of the hard fittings. What is the role of hydraulic transition joints?

As the contact surface between two different metals is easy to be oxidised, two metals are connected together, the contact surface will soon be oxidised, the contact resistance will increase, and then there is a vicious circle, followed by heating and contact with the increased resistance, will be the machine burning, the use of hydraulic transition joints can avoid this phenomenon.

(1) Pre-assembled

(2) Prohibit the addition of fillers such as sealant. In order to obtain a better sealing effect, the sealant will be applied to the collar, as a result, the U.S. threaded transition joint sealant is washed into the hydraulic system, resulting in the failure of the hydraulic components clogging.

(3) When connecting pipes, the pipes should have enough deformation allowance to avoid the pulling force of the pipes.

(4) When connecting pipes, lateral force should be avoided, and excessive lateral force should not make the sealing not strict.

(5) When connecting pipes, it should be done once and avoid disassembling many times, otherwise the sealing performance will be reduced.

The material of ferrule precision seamless steel tube is mainly divided into carbon steel and plastic, the top cover and bottom are made of carbon steel, and the middle tube is made of plastic. The internal plastic is not ordinary plastic, it is highly polymerised. It is made of sheet metal, stamping and other processes. Its surface treatment is galvanised, which can also be treated according to the specific environment and customer's requirements, effectively preventing the surface oxidation of the plastic part of the pipe clamps from necrosis. It consists of three parts: top and bottom plates, pipe clamps and screws and nuts.

Hydraulic pipe joints many people have never heard of, not to mention what it does. I searched for relevant information, and now share the principle of hydraulic pipe joints and cleaning methods, I hope to be able to help you.

What is the principle of hydraulic pipe joints? How to clean it?

　　First, the introduction of hydraulic pipe joints

　　Hydraulic pipe fitting is a connecting component, a connecting joint between the high pressure oil pipe and the high pressure oil pipe, it has many classifications, which can be divided into welded pipe fittings, high pressure hoses, excessive pipe fittings, high pressure ball valves and so on.

　　Second, the principle of hydraulic pipe fitting

　　Different types of fittings have different principles, here I introduce the principle of welded fittings, welded fittings, as the name implies, is welded, joints and receivers with round seals. The structure of this pipe joint is relatively simple, the production cost is not high, easy to produce, and good sealing. Only the welding quality requirements are very high, mounting and dismounting is not convenient.

　　Third, the cleaning of hydraulic pipe joints

　　Hydraulic fittings cleaning is divided into paraffin cleaning and pickling two kinds of paraffin cleaning is mainly for copper and stainless steel pipe, first of all to clean the pipe and joints removed, with a cloth dipped in paraffin to clean the internal measurement of the view, and then the ends and joints directly soaked in paraffin inside the cleaning can be. After cleaning the standard is not able to have visually visible pollutants. Pickling is mainly for the serious corrosion of the steel pipe, the first degreasing, in the water wash, and then rust, and then to be neutralised with lye, pay attention not to the pipe mark to wash away.

　　On the principle of hydraulic pipe joints and cleaning way to introduce so much, I hope that after reading this article you can have an understanding of the hydraulic pipe joints.

In some factories, it is estimated that many employees have heard of the problem of hydraulic joints. Stainless steel hydraulic joints are a particularly important component of machinery and equipment, it is mainly composed of electric motors, hydraulic pumps, hydraulic reversing valves and so on. However, most people do not know much about this joint, the following will give you an introduction to the stainless steel hydraulic joints related issues.

What are the applications of stainless steel hydraulic fittings?

　　First, what are the areas of application of stainless steel hydraulic joints

　　From the 1930s, stainless steel hydraulic fittings have been widely used in some capitalist countries, and have not been eliminated with the passage of time. Although its connector body and the structure of the connector nut form has not changed much, but in order to comply with the development of the whole era, it has developed into the current fourth generation. Because it is a component of the hydraulic pipe connection, so it plays an important role in the machine or other liquid pipeline.

　　Second, its role in the end what are the benefits

　　Speaking of hydraulic fittings, in fact, most people do not know much about it, just think it is a component, the use of a relatively wide range. However, it can be used in the process of effectively reducing the production process and production and processing links, and ultimately can achieve the purpose of cost control.

　　Through the above introduction, it is estimated that you have a simple understanding of this joint. In fact, although it is made of stainless steel metal products, however, it is used to do the connector, not only has the corrosion resistance, wear resistance and high toughness, at the same time it produces a gap is relatively small. If it is separated from some base metal, it is also relatively strong, and the connectivity is particularly good. But we also need to be careful when using it, to avoid causing some unnecessary harm.

Copper and aluminium transition joints are mainly used for two or more kinds of cables and pipes due to different models, must be connected by a transition joint. This product is now widely used in the manufacturing industry, electric power, aerospace, railway and other industries, especially the copper-aluminium transition joints, is currently the most mainstream joints, I will take you to understand the use of copper-aluminium transition joints and installation precautions.

Copper and aluminium transition joints use and installation process precautions?

　　First, the use of copper and aluminium transition joints

　　Copper and aluminium transition joints are used to connect the wires and busbars of industrial electric furnaces, vacuum appliances and transformers. Copper and aluminium transition joints can also be widely used in the construction of railways and aerospace industry, and can also play a role in the welding of copper and aluminium transition joints, water-cooled radiators, electric power equipment connectors welding.

　　Second, the copper-aluminium transition joints installation precautions:

　　Copper and aluminium transition joints and the bottom valve need to be installed in a vertical way, the flow of media between the bottom-up way. Straight through and lifting type copper-aluminium transition joints need to be installed in the horizontal pipeline. Swivel type copper-aluminium transition joints are not subject to any restriction on the installation position, but the installation process is usually in a horizontal manner, but can also be installed in horizontal or inclined pipelines. Copper-aluminium transition joints are installed at the bottom of the pump, of course, in the process of installation need to pay attention to the direction of flow of the media, the valve body should be marked with the direction of the flow of the media, otherwise it is easy to lead to the media flow is interfered with.

　　The above is about the use of copper-aluminium transition joints and the installation of the places that need to be noted, the product is currently the mainstream of the cable or pipeline connection products, in the manufacturing industry, industry and other fields are widely used, so that the product has a deep understanding of the future will also be able to avoid encountering difficult problems in the use of the process.

Transition joints due to the body can be applied to a variety of industrial enterprises to meet the needs of the use of the body, so it is also considered to be a more common joints, and as an important part of the transition, in the installation must not be sloppy, otherwise it is easy to cause leakage, some special industries and even prone to safety accidents, so we should be clear about transition joints body in the installation of what are the steps, the following is a transition by me to introduce a specific Joint body installation steps:

　　I. Pre-installation inspection

　　In the transition joint body should be installed before all the parts to check to see whether the parts shortage and whether the parts are damaged, whether there is a wrong connection phenomenon.

　　Second, parts splicing

　　All the parts that can be assembled into one should be assembled and spliced to lay a good foundation for the final assembly, and the process should try to ensure that the connection is compact to avoid leakage.

　　Third, bolt fixing

　　All the assembled parts of the whole with bolts and nuts for fixing, to ensure that the degree of solidity of the fixed, but not too tight, easy to damage the parts.

　　Fourth, adjust the position

　　Install the final assembled transition joint and adjust the final position to ensure that it can work properly.

　　Fifth, test performance

　　Finally, to test the performance of the transition joint body, work test to detect whether there will be leakage and whether the installation is loose, to ensure that it will not appear security problems.

　　Through the above introduction I believe we have a final knowledge of the transition joint body installation steps, transition joints as an important transition point of machinery, its significance can be imagined, so in the installation of its focus on observation, the steps are a step can not be wrong, to avoid the emergence of serious safety issues.
