記事の内容

The copper tube shall be heated and welded first, and then the joint shall be heated until the heated part turns dark red. At this time, when the filler metal contacts the tube, the filler metal shall melt.

Red copper bars in other regions basically follow the price trend of Tangshan, in which the bid of Jiangsu Steel Works tends to be higher, and most of the downstream prices are asked, and the overall market transaction is fair. The steel mills in Wuan are limited in receiving orders, and the market resources are tight. Most of the merchants are reluctant to sell. Shanxi billet market offers vary, and it is difficult to clinch a deal. The willingness of downstream customers to receive orders is weak, so they hold a cautious wait-and-see attitude. At prepresent, the steel market is in the "golden third" peak season. The market has a good expectation of the future market and a strong willingness to support prices. It is expected that the prices of Tangshan mainstream billets will be stronger next week.

上海ased copper tube is made of oxygen free copper rod, which has good processing characteristics and can be punched bent and other process design requirements. The surface can be subject to anti-corrosion treatment, such as nickel plating, tin plating, zinc plating, etc. The surface anti-corrosion can reach hours of fog test. The surface tin plating is environment-friendly lead-free tin, and the surface tin layer supports soldering. T degreased copper tube is mainly used for communication cabinet, transformer, charging pile box type substation and other electrical facilities. The copper bar is harder than the plastic pipe and has the degree of common metal (the strength of the cold drawn degreased copper pipe is equivalent to that of the steel pipe with the same wall thickness). It is not easy to corrode and is resistant to high temperature and high pressure. It can be used in various applications. The main material of copper bar is copper. The melting point of copper is as high as ℃, and the temperature of hot water can be ignored for degreased copper pipe, so as long as it is used correctly, there is no need to worry about safety. When choosing to decorate the house, few people ask about the water supply pipe of the house. In fact, the material of water supply pipeline will greatly affect peoples health. T copper tube has strong capacity. Escherichia coli in the water supply will not continue to breed in the degreased copper tube, and more than % of the water will disappear after entering the degreased copper tube for hours. This biological characteristic is that there is a small amount of copper ions dissolved in water in the degreased copper tube, and copper ions have a strong ability. Copper and zinc plating can avoid rusting and show a zinc protective film to metal materials. The conductive metal material repair and color enhancement care agent I can generate the thickness of the metal material epoxy protection layer and the pipelincathodic protection layer, which can resist extreme weather and is suitable for the long-term surface of metal materials. The actual effect of salt and water corrosion resistance is good. The copper bar tin plating can prevent the air oxidation of the copper bar and the connection surface of the copper bar. In addition, the melting of metal tin and copper will produce aluminum alloy, which will improve the adhesion of copper strip coating. In addition, the conductivity of metal tin is good. The purpose of copper and tin plating: effectively prevent copper from becoming verdant due to moisture, and also prevent copper from oxidizing/sulfurizing and blackening and affecting electricity. The service life of the tinned copper tube is several times or even more than ten times, marine climate or cold air is easy to turn black or produce copper green when oxidized, the copper bar surface shall be tinned for the total area, the resistance and conductivity of the steel bar lap surface.With the continuous development of industry, the mainstream spot price quoted by Lianzhong was - yuan/ton, and the tax inclusive base price quoted by Hongwang and Chengde was - yuan/ton. On a month on month basis, part of the producing areas recalled yuan, and the mainstream tax inclusive base price in the market changed from strongeak in the - plastic coated copper pipe supply and demand relationship. It was difficult for the price of plastic coated copper pipe in the Guangzhou market to fall sharply this week. Second, headers and main steam ducts of domestic HP UHP and subcritical power plant boilers. Third, large diameter pipes are mainly used as headers and main steam pipes with steam parameters below ℃.

今日は開場します.梓潼派先物は横ばいだったが,全体の市場は停止した.その後,市場の心理状態はあまり変わらなかったケント.価格は安定しているが,部の規格は協議が必要で,協議の範囲は-元前後である.市場の全体的なリズムは安定していて冷淡である.冬中期,東北地方全体の市場は伝統的な閑散期に入り,全体の市場の収束は力がない.すべての会社が商品を販売している.在庫整理のため,瀋陽の在庫レベルは非常に低く,上海316 Lステンレスパイプ,すべての建設現場が閉鎖されている.低温による輸送圧力を除いて,市場は惨憺たるものだった.

In the first ten days of May, the overall order receiving quantity of Tianjin Hebei Henan Plate Plant was not ideal. According to the monitoring data, the overall order intake of medium and heavy plate mills in Tianjin Hebei Henan region in the first ten days of May remained stable and weak. Due to the weak market shock,上海1060アルミニウムストライプ, the overall order intake of the spot steel market was relatively weak. The total quantity of orders received in the first ten days of May is only about tons, while at the end of April, the total quantity of post settlement agreements of main steel plants can exceed tons.

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.

It is said that due to the optimistic future and tight resources, some iron plants do not take orders temporarily. The steel mills in Liaoning have increased their enthusiasm for purchasing steel. The iron mills have delivered well, and the price of raw materials has risen, so the iron price has risen. The iron mills have a high enthusiasm for producing steel,上海304 Lステンレス板, so there is not much cast iron resources, and the price has risen. A few steel mills in Tangshan began to purchase a small amount of steel for smelting, and most steel mills are still on the lookout for inquiry. Under the background of increasing cost and gradual release of demand, the pig iron market is performing well and is expected to continue to operate strongly in the short term.

値段が安いRed copper plate has ductility. Pure copper, which is as big as a drop of water, second onlyver in common metals. But copper is much cheaper than silver, so it has become the "protagonist" of the electrical industry.

The hard copper tube is not artificially treated after being drawn or extruded, so that it can be naturally formed. At this time the organizational form in the copper tube is full. This kind of copper tube is more likely to crack and is not suitable for bending. Therefore, the hard copper tube is generally straight.
