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, 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, 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.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.Cartagena,The more residual chloride ions, the deeper the corrosion pit of water.When stacking, it shall be stacked reasonably and placed first.Dakoro,In Jiangyin market, another distribution center, the overall inventory of the current circulation link is about tons, slightly lower than the normal level. At the beginning of this week, the price gap between Jiangyin prices and those in the north has also been able to correspond to the slightly lower circulation inventory. However, from the perspective of the policy port of the steel plant, Hengrun, Dada, etc. is relatively normal, and the amount of resources in the later period remains stable. The overall inventory of Lecong market remains at about to tons, which is a medium normal level, and the recent spot price of Lecong market has a large gap with that of the north.When welding, just add enough filler metal to fill the capillary gap. Too much filler metal will only form a ball at the bottom of the joint or run into the pipe.Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.

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.Copper pipe has the characteristics of firmness and corrosion resistance, and is the choice for the installation of water pipe, heating pipe and refrigeration pipe.It has excellent conductivity, thermal conductivity, ductility and corrosion resistance.Inspection items,Cartagena60SI2MN alloy round steel,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.Copper pipe has the characteristics of, and is the choice for the installation of water pipe, heat supply and refrigeration pipe.The ex factory price of Linyi Pipe Factory has decreased by yuan for cash Baocheng ( * mm, yuan for Jin Zhengyang yuan, yuan for Ruigang Lianlian, yuan for Baoda yuan, yuan for Meixin yuan, and yuan for Taizong yuan.

The room temperature tensile strength of the annealed red copper sheet is ~ kgf/mm, the elongation is ~%, and the Brinell hardness (HB) is ~quality standard,The application of copper tube The copper tube is generally used in the heat exchange equipment, and the low-temperature pipeline in the oxygen production equipment can also be used. Some relatively thin copper tubes can be used to transport some pressurized liquids, and can also be used as pressure measuring tubes in instruments; In addition, the copper pipe is relatively firm, unlike other metals, which are easily corroded, so now many water pipes and refrigeration pipes used in buildings will choose to use the copper pipe.As theation effect of copper material on the agent is weak,CartagenaCopper plate, the dissolved oxygen and air bubbles in it will corrode it.Copper pipe has the characteristics of, and is the choice for the installation of water pipe, heat supply and refrigeration pipe.Cartagena,Three of the five major application fields of copper plate,Cartagena40cr alloy steel plate, copper bar and copper tube: copper is used to manufacture, - tons of copper are needed.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.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.
