Schoenberg BerlinBronze tubeQuickly master the 4 major steps of debugging and practical

Generally, oxygen aylene is used as the gas source and LPG welding tool is used for heating. The torch of the welding tool shall face the joint and then continuously heat the whole joint. This will avoid excessive local heating.Save materials and total cost, stability and performance, and can save maintenance.Schoenberg Berlin,How to make copper tubes shine copper is stable in dry air, but the surface of power copper tubes is easy to be corroded in humid air, generating a layer of green material, commonly known as & quot; copper green& quot;, and its main component is & quot; basic copper carbonate& quot;. So, how to remove verdigris? We can remove the verdigris by mechanical friction, but this is not only troublesome, but also will damage the surface of the bronze. Here s a good way to remove verdigris. Use a measuring cylinder to measure ml of concentrated ammonia water and put it into a beaker, then add ml of distilled water, stir it with a glass rod to prepare ammonia solution, that is, wipe copper water. Copper rubbing water can react with verdigris to form soluble blue copper ammonia complex, thus removing the verdigris. In order to improve the effect of removing verdigris from the copper polishing water, chalk or talcum powder can also be mixed into the copper polishing water which can increase the mechanical friction, fully expose the deep layer of copper rust, ensure the complete reaction of verdigris and ammonia, and make the copper surface smooth and bright. Dip cotton in copper water and repeatedly scrub copper products with copper rust. Soon, the copper rust disappeared from the surface of the bronze ware, and the copper products showed a bright metallic luster again, soak them in the copper scrubbing water for a while, and then scrub them with cotton dipped in the copper scrubbing water.Advantages: good quality, fine structure, high pressure resistance, large bending deformation, and large size copper tube can be produced.Jinan,On October ,Schoenberg Berlin201 stainless steel plate, according to the Economic and Information Commission oong Province, at the end of September , Shandong Province had resolved the overcapacity of million tons of pig iron and million tons of crude steel, and all the de capacity equipment had been shut down and withdrawn. On October , the Development and Reform Commission of Handan City released the Plan for Handan City to Eliminate Excess Iron and Steel Capacity. Statistics show that the iron making capacity of Handan in was million tons and the steel making capacity was million tons.Advantages of red copper tube Durability: copper has stable chemical properties, integrating cold resistance, heat resistance, pressure resistance, corrosion resistance and fire resistance, and can be used in different environments for a long time.The simplest way is to use copper cleaner. Brass red copper, bronze, etc. can be used. Oil stains, fingerprints, oxide layers, etc. on the surface can be cleaned with copper cleaner first.

Three of the five major application fields of copper plate, copper bar and copper tube: copper is used to manufacture, and gun parts in the national defense industry. Every million rounds of copper are produced, - tons of copper are needed.Finished products must be stored indoors. During storage, they should be protected from direct sunlight to the copper tubes. During the transfer, transportation and loading and unloading of copper tubes, rain should be avoided; In summer, pay attention to the principle of first in first out to reduce no loss; The copper pipe loading process is better carried out indoors to avoid the copper pipe being exposed to the sun, so as to accelerate the speed of the outer wall of the copper pipe. After the loading is completed, at least two layers of canvas shall be used to tightly wrap the whole vehicle materials; After loading, if the truck can not depart in time, the truck shall be driven to the back of the sun to prevent the goods from being exposed to the sun for a long time to absorb heat.However it is difficult to change this situation too much in the short term. It is expected that the domestic strip steel price will mainly rise in the short term. It is reported that in order to pursue profits, Ltd. is currently increasing the supply of hot coils. It does not rule out that more steel mills in the future are inclined to one end of the plate in pursuit of profits Tangshan Iron and Steel Group Co., or to lay hidden dangers for the decline. As far as tomorrow is concerned, the price may still maintain a narrow range of shock operation pattern.technical service,Disadvantages: low output, high production cost and high price. Extrusion copper tube process is a stable and excellent copper tube production method at home and abroad at present. Only the copper tubes produced by this process are more suitable for the field of heating and ventilation, which is the development direction of copper tube industry in the future.Extrusion method: This production method is to cast copper ingots after smelting, and extrude copper tubes by large extruder after secondary heating.The difference between hard copper tubes and soft copper tubes in use Hard copper tubes can only be used as straight tubes and cannot be bent. Therefore, they are generally used in power plants, switches of electrical equipment and places where the connection points are far away and do not need to be bent. Compared with soft copper tubes, the price of hard copper tubes will be lower. Although the name of the soft copper tube is soft tube, it can also be used as a hard tube, so the soft copper tube is used in more places, and can be used in a straight tube way, asell as in a coiled tube way. The length of the copper tube can be longer if the coil is used. If the connection point is longer, it can be cut randomly according to the length, so as to prevent leakage when welding the copper tube. Soft copper pipes are used in many refrigerators, air conditioners and other places where bending pipes are needed. When we use copper, we need not consider the preservation problem unless we buy a small amount at home. For example, large manufacturers use copper units to buy a large number of copper pipes once,Schoenberg BerlinAluminum rod, so there will be a problem. I believe some people do not know how to store unused copper materials, Now let s ask our staff to introduce the storage method of copper for you.

First of all, we should set up a warehouse. The temperature in the warehouse should be generally kept at - ° C, while the humidity should be normal. The room should be kept ventilated.investment,Let s elaborate on the advantages of copper pipe materials: copper pipe floor heating refers to a heating method that uses hot water as the thermal medium, circulates in the copper pipe heating pipe, heats the floor, and heats the floor through the ground in the form of radiation and convection heat transfer. I. The copper tube has fast heat dissipation effect and strong heat resistance. Even under the condition of high temperature water supply, the service life of the floor heating tube will not be affected. Two. Copper pipe is a metal pipe,o it is not easy to scratch. Therefore, it is not easy to leak. Three. High temperature resistance, high pressure resistance, relative to any ordinary plastic pipe. Copper tube floor is warm and resistant to high temperature and pressure. Four. Long service life. Five.Soft water is easy to cause copper pipe corrosion.Advantages of red copper tube Durability: copper has stable chemical properties, integrating cold resistance, heat resistance, pressure resistance, corrosion resistance and fire resistance, and can be used in different environments for a long time.Schoenberg Berlin, the market price of Zhengzhou copper bar was basically stable. According to the monitoring data of the Lange cloud business platform, the current market price of * mm Linyi copper bar was yuan (ton price, the same below), the * mm copper bar was yuan, and the * mm copper bar Henan copper bar was yuan.Advantages: good quality, fine structure, high density, high pressure resistance, large bending deformation, suitable for frequent cold and heat exchange large temperature difference in working environment, and large size copper tube can be produced.The market opened today. Although the performance of Zitong Pai futures was modest, the overall market has stopped. The market mentality has not changed much sincekend. The price is stable, but some specifications are subject to negotiation, and the negotiation range is about - yuan. The overall rhythm of the market is stable and cold. In the middle of winter, the overall market in Northeast China has entered the traditional off-season, and the overall market has ended with little improvement. All companies are selling goods. The inventory level in Shenyang is very low due to the inventory clearing, and all construction sites have been closed. In addition to the transportation pressure brought by the low temperature, the market was bleak.
