the overall market has stopped. The market mentality has not changed much sincekend. The price is stable, but some specifications are subject to negotiation,Kele bangbesarCopper tube, 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.Copper pipe has the characteristics of, and is the choice for the installation of water pipe, heat supply and refrigeration pipe.Kele bangbesar,The above two types of thermal connection usually use the term welding, because in both cases, thermal conductivity,Extrusion method: This production method is to cast copper ingots after smelting, and extrude copper tubes by large extruder after secondary heating.Because of the characteristics of copper itself, it is very easy to rust and corrode in places with high ambient humihumidity. If we often use it, the problem will be smaller, but if it is placed for a long time, the copper will be damaged. Many people do not know how to treat the copper surface? Now let the staff answer for you.Today, the price of tube billets is up and down. At present, Jiangxin hot rolling is yuan, continuous casting yuan is down yuan, Dongfang hot rolling yuan is down yuan, Luli hot rolling yuan is down yuan, Tiangang hot rolling an is down yuan, production is stopped in mid January, Weigang hot rolling yuan is up yuan, continuous casting yuan is up yuan,Kele bangbesar201 stainless steel plate, Huaigang yuan is up yuan, Zhongtian yuan, Changqiang yuan, Linggang yuan.

Although the opening continued the weak trend the intraday transactions improved, and the prices of some copper bar manufacturers rose. From the specific situation, although the manufacturer feedback that the shipment is average, the mentality is relatively calm, the market inventory is not much, and the manufacturer is not willing to significantly reduce the price. In terms of the market, the transaction of strip steel is better than other steel varieties, and the downstream mainly focuses on callback buying without panic inventory clearing. It can be seen that although the steel market continues to shake, the overall demand for strip steel remains in a good state.Disadvantages: The pipe structure is loose, and it is not resistant to high pressure. It is only suitable for the production of small air conditioning copper pipes.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.Latest consultation,The simplest way is to use copper cleaner. Brass, bronze, etc. can be used. Oil stains fingerprints, oxide layers etc. on the surface can be cleaned with copper cleaner first.antages: low production cost and high production efficiency.The market price of Zhengzhou copper bars is basically stable, Shandong Luli tube blank slightly reduced by yuan and the shipment is not good. In terms of tube blank: today, and the current mainstream ex factory price is - yuan. In terms of pipe plant: Linyi Pipe Plant locked the price for a week. With a stable market mentality the factory price of hot rolled seamless pipes is now between - yuan. On the market side: with the arrival of the off-season, traders generally ship goods at a high price. Replenishment is mainly to maintain the existing inventory, and there is no large replenishment plan. The demand is sluggish, and the market price of Zhengzhou copper bar is expected to be stable and declining.

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.Quality management,Today, the price of tube billets is up and down. At present, Jiangxin hot rolling is yuan, continuous casting yuan is down yuan, Dongfang hot rolling yuan is down yuan, Luli hot rolling yuan is down yuan, Tiangang hot rolling an is down yuan, production is stopped in mid January, Weigang hot rolling yuan is up yuan, continuous casting yuan is up yuan, Huaigang yuan is up yuan, Zhongtian yuan, Changqiang yuan, Linggang yuan.{} The copper pipe welding can be divided into soft welding and hard welding. The soft welding temperature is lower than ℃ and the hard welding temperature is higher than ℃. Hard welding is usually used for silver, gold, steel, copper and other metals. Its welding points are much stronger than soft welding, and its shear strength is - times that of soft welding.It can be wrapped with moisture-proof paper for moisture-proof protection. It can also prevent oxidation to a certain extent. If cracks or serious corrosion are found, they must be isolated.Kele bangbesar,Advantages: good quality, fine structure,Kele bangbesar321 stainless steel round steel, 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.It can be wrapped with moisture-proof paper for moisture-proof protection. It can also prevent oxidation to a certain extent. If cracks or serious corrosion are found, they must be isolated.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, 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, Now let s ask our staff to introduce the storage method of copper for you.
