Advantages and scope of application of copper tube ground heating At present, ground heating is not only a comfortable heating method, but also a symbol of modern life quality. More and more houses public buildings, sports facilities, industrial facilities and other places begin to use ground heating radiator, which is an important part of ground heating. Due to the corrosion resistance of copper, copper tubes are selected as the main material of radiator in many places.In view of the current overall price difference, the local copper bar price continued to rise at a high level today, while the regions outside East China did not show an obvious follow-up trend, and the local price still has the advantage of price difference with the Northeast and Central China regions. The local inventory pressure will be further reduced due to the small volume of local follow-up goods under the influence of production restriction, at present, domestic real estate control is still being tightened. The market s expectation of future demand is weakening, and the market s fear of heights appears after the price rises. Today, the market price of copper bars in Shenyang is stable and the shipment is poor.Lauca,When the purity of pure copper is higher, the corrosion resistance is better. Copper pipes processed with recycled copper are easy to cause corrosion due to impurities inside. (I) Problems that should be noted in copper pipe welding are generally %. % % or % silver electrode shall have good fluidity and be assisted by flux. The flux used shall be a flexible mixture or powder, with carbonization flame for copper pipe welding.For small diameter pipes, when using filler metal, the length of filler metal is allowed to be equal to the diameter of the pipe,Lauca2507 stainless steel plate, which is enough to fill the weld crater. One of the five major application fields of red coppr plate T,LaucaRed copper tube, red copper bar and red copper tube: copper is the most widely used and used in the electrical and electronic industries, accounting for more than half of the total consumption. Used for various cables and wires, motors and transformers, switches and printed circuit boards; In the manufacture of machinery and transport vehicles, it is used to manufacture industrial valves and accessories, instruments, sliding bearings, molds, heat exchangers, pumps, etc.Maicao,In addition, it is not easy to be corroded and can adapt to various environments. It can be used normally at low and high temperatures, so copper pipes need to be selected for many times in other places.The blowpipe shall be perpendicular to the lead pipe during welding, and the flame shall be moved continuously to prevent local overheating and the flux from carbonizing before filler metal is added.The blowpipe shall be perpendicular to the lead pipe during welding, and the flame shall be moved continuously to prevent local overheating and the flux from carbonizing before filler metal is added.

Some steel mills in Liaoning are interested in purchasing pig iron, but the local resources are tight, and the iron mills quotations are on the high side, resulting in a stalemate between supply and demand. The demand for cast iron and ductile iron in Jiangsu, Shandong, Shanxi, Hebei, Henan and other regions is sluggish, and the inventory pressure of iron mills is increasing. As the price of raw materials decreases, the quotation of iron mills continues to decline. At present, and there is no positive boost. The short-term pig iron market is weak and difficult to change.The water quality at the place where the copper pipe is required to be installed shall be studied, and the appropriate water quality and water flow shall be selected for pipe distribution to prevent the root cause.The room temperature tensile strength of the annealed red copper sheet is ~ kgf/mm, the elongation is ~%, and the Brinell hardness (HB) is ~How many?,Red copper plate has ductility. Pure copper, which is as big as a drop of water, can be pulled up to two kilometers of thin wire or rolled into a transparent foil larger than a bed. The most valuable property of red copper row is that it has a very good conductive second onlyver in common metals. But copper is much cheaper than silver, the continuous decline of iron ore port inventory may end. In addition so it has become the & quot; protagonist& quot; of the electrical industry.Red copper inventory may end the trend of continuous decline. With the increase of production restriction of steel enterprises and the pressure of demand, according to the new statistics of * *, the available days of imported iron ore of steel mills are days,LaucaRed copper bar, which is one day lower than that before the National Day, and is on the high side of history. The steel mill said that at present, the iron ore inventory basically meets the production requirements. Considering the future production reduction and restriction, in September , China s imported iron ore * * * broke through the million ton mark, reaching million tons, a record high; From January to September, China s iron ore import increased by % to million tons, and the annual import volume is expected to exceed billion tons. However, judging from the shipment of imported ores after the National Day, due to the rapid declinecline in iron ore prices, which reduced the enthusiasm for the shipment of imported ores. In addition, environmental protection inspection has become stricter, and the supply of some domestic mines has been greatly affected. The current operating rate of domestic mines is percentage points lower than the previous peak, the elongation is ~%, and the Brinell hardness (HB) is ~Price,In terms of steel billets: at :, some steel billets in Changli were reduced by , and the current carbon square billets were delivered with tax of yuan. After the th National Congress of the Communist of China, the market had doubts about the uncertainty of environmental production restriction and was still waiting for a clearer direction. Therefore, it can be seen that at this stage, there was no unilateral market for either futures or cash, and there was no definite pattern of ups and downs. According to the monitoring data of Lange Iron and Steel s cloud business platform, as of the time of publication, Tianjin Youwelded Line: the steel mill reported: Rongcheng # yuan/ton, B yuan/ton; Jiujiang # - # to Tianjin yuan/ton; The arrival price of Xinji Aosen # is yuan/ton, and that of B steel is yuan/ton; Jiyuan # yuan/ton B steel yuan/ton; Fulen # yuan/ton; Weigang # yuan/ton, B steel yuan/ton.Regularly inspect and monitor the copper pipe to reduce the loss caused by copper pipe corrosion.Extrusion method: This production method is to cast copper ingots after smelting, and extrude copper tubes by large extruder after secondary heating.Lauca,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.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, 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.This week (-, the market price of red copper bar rose, and the transaction was not ideal. On the bidding day of Shagang last weekend, the price was stable to support the market, and the rising of billets at the weekend drove the market up in a wave, and the price of variety wire rods also rose by yuan at the weekend. However, it was reported that the deal was very poor, which led to the price being s table for the next two days. Until Wednesday, due to the negative outlook on the future market and the reduction of steel billets in the afternoon spiral diving, the market lowered the price. Market price changes, Xinji rose yuan on the rd; For the future market, the off-season is coming, the demand is weakening, and the market wait-and-see mood is getting stronger. But when winter comes, the environmental protection inspection is becoming more and more strict, which supports the market. It is expected that the price ofety wire rod will be adjusted in a weak way in the short term.
