Pasakmis.How to preserve the copper tube? In order to protect the excellent performance of copper pipes from the impact of the environment we need to do the following: First, select appropriate sites and warehouses, and keep the surrounding environment dry and ventilated. Do not stack together with acid, alkali, cement, different directions, different internal pressures and different sizes. The results show that the stress at the crack tip is much greater than that at the crack center. The crack shape has little effect on the stress. With the increase of the included angle between the crack direction and the pipe axis the stress at the crack tip first increases and then decreases. With the increase of the pipe internal pressure, crack depth, and crack length, the stress at the crack tip increases linearly. Among them, the effect of crack length on the stress at the crack tip is smaller than that of internal pressure and crack depth. During the construction and operation of long-distance pipeline, due to the influence of pipe manufacturing defects, welding defects, internal and external loads, stress concentration, corrosion defects and other factors, the pipeline will produce cracks and expand cracks, which is the most dangerous defect of long-distance pipeline and the main reason for pipeline failure. At present, pipeline cracks are mainly determined by internal testing and non-destructive testing after excavation. Among them, ultrasonic internal testing has a good identification rate for cracks with a length of more than 25 mm, a depth of more than 1 mm in the base metal or a depth of more than 2 mm in the weld; Magnetic flux leakage internal detection has a certain detection rate for cracks with opening more than 0.25mm but it is difficult to identify and quantify. In NDT, magnetic particle, penetration, eddy current and radiographic methods have high detection and identification rate. The generation and propagation of cracks will cause local stress concentration in the pipeline, which is prone to brittle fracture, fatigue damage, corrosion damage and other failure phenomena, seriously affecting the service performance and reliability of long-distance pipeline. In this paper, the influence of crack shape, direction and size on the stress at the crack tip is yzed by studying the stress field distribution law of copper pipe cracks, which provides a reference for the prevention and control of pipe cracks. What problems will be encountered in the production of copper tubes. The production of copper pipe includes four steps: welding, forming, inspection and pipe expansion.

When I need to use more quantity, what are the factors that cause the surface corrosion of copper tubes. Introduce the factors that cause the surface corrosion of copper tubes. Surface pollution: The oil, dust, acid, alkali, salt, etc. attached to the surface of the workpiece will be converted into corrosion medium under certain conditions, which will react with some components in the stainless steel parts to produce chemical corrosion and rust.

Where can I find it?.Plastic coated copper pipe is a kind of non-metallic material pipe with light weight, high strength and corrosion resistance. The plastic coated copper pipe is made of glass fiber with resin base weight, which is wound on the rotating hollow floor step by step according to the processing technology regulations, and the stone sand is laid on the ground evenly for a long distance in the middle of the chemical fiber as the intermediate weathering layer. The price quotations of plastic coated copper pipes with different thicknesses are also different. Here, we will explain the factors that determine the thickness of the plastic coated copper pipe design scheme. Appearance and specification of mpp cable duct 1 Color: generally orange red, other colors can be implemented according to the contract of both parties. 2 Appearance quality: The inner and outer walls of the pipe fittings shall be smooth, clean and even, cracks, cracks, molting, dents, residues, dissolved discoloration lines and uneven colors. The inner holes of the pipe shall be laser cut and leveled and vertical to the pipe centerline. The inner holes shall be smooth and free of burrs. Specification: The length of pipe fittings is generally 6000 or 9000mm, there may be many key points. Pay special attention to the leveling and straightness of the road surface when threading, In other words, if the road surface is seriously uneven, it is seriously affected by external forces. Relevant countermeasures must be taken, and fine sand and dirt should also be prohibited from seeping into the pipe during the burial process, so as to diligently maintain its compliance with the regulations during the burial process. The process of embedding the plastic coated copper pipe involves the problem of marking. In fact, the marking that can be carried out according to this marking in the process of maintenance and repair is the key inspection index value of the commodity. If it is found that there is a problem with a certain section of cable, it is only necessary to find matching marks for immediate maintenance. Number of layers of cloth stacking: all layers are made strictly according to the design scheme, without additional construction, which increases the cost. 2 Resin: high temperature resistance, not easy to deform under stress. Plastic coated copper pipes are generally assembled from high-quality SMC water tank plates. Its characteristic is that it can select food grade stainless steel resin. Therefore, in view of the good water body, clean up the natural environment and zero pollution, the commodity development trend has certain characteristics such as high compressive strength, light weight, corrosion resistance, beautiful and generous appearance design scheme, and more convenient management methods in maintenance. Cloth quality: the specification of cloth surface is the same, and it is thick with blended cloth or pure old coarse cloth. The thickness of fiberglass filament winding: our products are high-tech support points of fiberglass anti-corrosion ring, which ensures the bearing pressure of the products. In addition, if you must select the thickened type, you can yze the vertical cross type difficult winding when winding the winding machine, until the thickness and compressive strength of the thickened type are basically achieved.

Pasakmis.One of the classification of copper tubes. The common wave shape is a single copper tube. Hyperbolic means that two different arcs overlap on the same surface, that is, starting from different circle centers draw arcs in two radii. The red copper tube is a module made of double curves designed according to the drawings. The red copper tube is light in weight, good in rigidity and high in strength. The shapes of the red copper tubes processed are different and can be processed into various geometric shapes such as arcs and spheres. It is beautiful, elegant and colorful. Let's talk about the two main methods of processing and forming the copper tube: The hot processing and forming method is to roll the copper tube to a roughly hyperbolic shape, then heat it, then slowly beat it with a hammer, finally cut weld, fold, polish and polish it. The whole process needs to be very careful to ensure the surface quality of the copper tube. This forming method is very suitable for parts with small model and large arc change. When the model size is relatively large and complex, it can be considered to break it into small pieces for forming, and then splice it into large pieces. For such copper pipes, and change one of the shafts into a concave type and the other into a convex type. This method can form a regular copper tube like a sphere, with a small processing range but it has great advantages for copper tubes with small radians. What problems should be paid attention to when designing the hyperboloid copper tube? Everyone knows that the design of the air conditioning copper tube is very important. To achieve the beautiful shape, exquisite workmanship and fashionable personality of the hyperboloid copper tube, first of all, the design is very critical. Some small copper tube companies are not mature enough in design and have not enough design experience, so they often have problems in design, Hyperbolic copper tube is very famous for preparing some details that we should pay attention to in the design. The sculpted copper tube is highly decorative, and the production and processing technology of hyperbolic shaped copper tube is relatively complex. Copper tube products with strong aesthetics. According to the design requirements, different shapes need to be molded for the sculpted copper tube, so the production process of sculpted aluminum veneer is relatively complex.

Four in one formula and process conditions Preparation of solution Take formula 1 as an example: mix the calculated amount of water for zinc oxide into a paste, slowly add it into the calculated amount of phosphoric acid under stirring until it is completely dissolved, then add zinc nitrate and tartaric acid, dilute it with water to 2/3 of the total volume, add sodium alkosulfonate and OP emulsion, and stir to make it completely dissolved. Then add chromium dihydrogen phosphate dissolved in dilute phosphoric acid, and add titanium sulfate. After all materials are added, dilute them to the total volume, stir them to make the solution even, cool them to room temperature, put a large amount of iron filings in the solution, and soak them for 2-3 days to make them contain enough ferrous ions. When the content of ferrous ion reaches above 7g/L, adjust the free acidity and total acidity of the solution to the specified value, and then the solution can be used at elevated temperature. When the ferrous ion reaches the above value, the phosphating speed is fast,Pasakmis201 stainless steel plate, the solution is stable, and the phosphating film is fine and dense. During operation, attention shall be paid to controlling the temperature. If the temperature is higher than 70 ℃, the degreasing technology of degreased copper pipe. How to make degreased copper pipe? The process flow of degreased copper tube? What are the characteristics of degreased copper tubes? Use of degreased copper tube? There are too many questions. Let's solve them at once. Everyone knows the copper tube. Nitrate reacts easily. The heater should be installed on the two walls of the tank, not on the bottom of the tank, to prevent local overheating. Stainless steel pipe or iron pipe should be used for heater, and lead pipe or copper pipe should not be used to avoid contamination of solution by impurities. What is degreased copper pipe? &The advantages of degreased copper pipe's comprehensive treatment of grease, rust removal, phosphating and passivation are described. This comprehensive treatment process can simplify the process, reduce the work area, save equipment costs shorten working hours,PasakmisTinned copper bar, in actual production improve labor productivity and reduce costs. This method can only be used in the occasions where the requirements for coating quality are not high.However, due to the amount of oil contamination, light and heavy rust, the consumption rate of each component in the solution is different, so attention should be paid to adjustment and control to maintain its due role. What is the degreasing copper tube? &I have roughly known the degreasing methods of degreasing copper tubes: solvent degreasing alkali degreasing, high pressure hot water degreasing ultrasonic degreasing, electrolytic degreasing, etc. 1 Solvent degreasing: use degreasing solvent to dissolve the oil on the surface of red copper pipe, collect it together into a container, volatilize, collect and reuse the volatile solvent, and separate the pollutants from the circulation system. This method was used in the early stage, which has problems such as low cleaning efficiency, difficult maintenance, and environmental pollution. In recent years, many kinds of surfactants have been developed.
