according to the Economic and Information Commission oOng Province, at the end of September , and all the de capacity equipment had been shut down and withdrawn.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.According to * * new data, in September , China ème ; * broke through the million ton mark, a record high; From January to September, China & dg ; 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, the iron ore price index once fell below $, 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, which is likely to decline further in the future.ПекинРегулярно проверяются и контролируются медные трубы, чтобы уменьшить ущерб от коррозии.Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.Ричардс Бэй,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.После очистки трубопровода флюс и флюс должны наноситься в промежуток между интерфейсом и зазором. Над поверхностью соединения должно быть тонко нанесено достаточное количество флюса и немедленно собрано чтобы пыль и грязь не загрязняли зазор капилляра.С наступлением отопительного сезона медные ряды имеют слабую сырьевую поддержку. Под влиянием отопительного сезона и экологических ограничений производства сталелитейные заводы в некоторых районах начали осуществлять меры по ограничению производства доменных печей в отопительный сезон, и спрос на железную руду снизился. Кроме того, сегодня в Таншане была обнародована политика ограничения производства. В период с ч. м. октября по ч. м. октября осуществляются меры по ограничению производства, предусмотренные в настоящем циркуляре.

According to * * new data, in September , China ème ; * broke through the million ton mark, reaching million ton s, China & dg ; 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, which is likely to decline further in the future.Разработка норм оценки технического обслуживания медных труб.Do not store too many other products, especially other acid materials and alkali materials, in the warehouse to prevent mutual reaction. сколько нужно ,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.To sum up, due to the influence of factors such as the current spot market price is much higher than the expected winter storage price of merchants, the gradual emergence of supply and demand pressure, and the weakness of raw material support, among which the contraction of market demand has a greater impact. Therefore the author believes that in the short term, the spot building materials do not have the possibility to rise significantly, and the price of building materials may main operate in shock,ПекинМедная труба, but with the shrinking demand, the supply and demand pressure becomes prominent, However, considering the influence of winter storage and other factors, It is still possible for merchants to lower the spot price in November.Do not store too many other products, especially other acid materials and alkali materials, in the warehouse to prevent mutual reaction.

Кроме того, он не подвержен коррозии и может адаптироваться к различным средам. Он может нормально использоваться при низких и высоких температурах, поэтому в других местах необходимо несколько раз выбирать медные трубы. техническое новаторство ,Для труб малого диаметра, при использовании наполненного металла, допустимая длина наполненного металла равна диаметру трубы, достаточной для заполнения сварной ямы. Одна из пяти областей применения красного коп.R - пластины T, медные стержни и медные трубы: медь наиболее широко используется в электротехнической и электронной промышленности, на которую приходится более половины общего потребления. Для различных кабелей и проводов, двигателей и трансформаторов, переключателей и печатных плат; В производстве машин и транспортных средств он используется для изготовления промышленных клапанов и аксессуаров, приборов, подшипников скольжения, пресс - форм, теплообменников, насосов и т. Д.In order to solve these problems, silicon containing welding wires are commonly used in welding, because silicon will form a layer of dense silicon film on the surface of the molten pool, which will hinder the evaporation of zinc and prevent the invasion of hydrogen.For small diameter pipes, when using filler metal, the length of filler metal is allowed to be equal to the diameter of the pipe, which is enough to fill the weld crater. One of the five major application fields of red coppR plate T, 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, heat exchangers, pumps, etc.Пекин,При укладке следует разумно укладывать, отдавая приоритет размещению.Что касается методов хранения медных материалов, мы должны хранить медные продукты, которые мы покупаем,Пекин316L Трубы из нержавеющей стали, продлевая срок службы меди и обеспечивая ее работоспособность, чтобы избежать ненужных потерь.For small diameter pipes,ПекинТ2 Бронзовый, when using filler metal the length of filler metal is allowed to be equal to the diameter of the pipe, which is enough to fill the weld crater. One of the five major application fields of red coppR plate T, 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.
