In view of the current overall price difference， the local copper bar price continued to rise at a high level today， 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， and the price support of copper bar is still strong. However， at present， domestic real estate control is still being tightened. The markets expectation of future demand is weakening， and the markets fear of heights appears after the price rises.Today， so it becomes the first choice for modern contractors to install the water pipe and is solid and corrosion resistant. It will not crack when compared with the ambient temperature， heat supply pipe and refrigeration pipe in all residential commercial houses.

Extrusion method: This production method is to cast copper ingots after smelting and extrude copper tubes by large extruder after secondary heating.
라 퍼 스 빌Tangshan billets rose sharply last weekend， steel mills in some northern cities implemented production restriction， and some domestic economic data improved， which boosted manufacturers confidence. Today， steel prices generally rose. However， with the approaching meeting and the rainfall in the south caused by the typhoon， the construction progress of the downstream construction site is affected， which is not conducive to the continuous demand. The high spot price transaction today is weak，모터 로304 스테인리스 강판， which is difficult to support the continuous rise of steel prices. It is expected that the building materials market will maintain a volatile trend tomorrow，모터 로6082 알루미늄 바， and some businesses may reduce prices and take goods.

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 Steels 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.
After the pipe is cleaned， the welding flux and flux shall be immediately applied to the interface and the bayonet clearance. Sufficient flux shall be thinly coated on the mating surface and assembled immediately， so that dust and dirt will not pollute the capillary gap.
Water quality， water flow and flow of the pipe.

품질 개선However， it is difficult to change this situation too much in the short term. It is expected that the domestic strip steel price will mainly rise in the short term. It is reported that in order to pursue profits， Tangshan Iron and Steel Group Co.， Ltd. is currently increasing the supply of hot coils. It does not rule out that more steel mills in the future are inclined to one end of the plate in pursuit of profits， or to lay hidden dangers for the decline. As far as tomorrow is concerned， the price may still maintain a narrow range of shock operation pattern.

To prevent core problems of copper tubes， the outlet tempmperature of copper tubes should be well controlled. The cooling capacity of the annealing furnace in the cooling stage should be improved by equipping a refrigeration unit for the annealing furnace， so as to ensure that the outlet temperature of copper tubes does not exceed ℃. By controlling the outlet temperature of copper tubes， the problems of the core of coil tubes and the inner wall of the purging inlet end can be solved.
If you want to avoid this kind of situation for a long time， you can choose passivation treatment. In this way， not only is the copper surface serious， it can be cleaned under normal circumstances， but it is not a big problem to keep it in the air for one year or more after ultrasonic treatment and immersion treatment， so this effect is very good.
모터 로The price of tube billets was adjusted and lowered mainly due to the production restriction of environmental protection and the weak demand for temperature and weather. Recently， the terminal demand has also shrunk due to the sudden drop in temperature， causing a weak shock. According to the communication with local traders in Cangzhou， various good news last week led to the shipment of thermal expansion pipes in Cangzhou in the past two weeks， which is better in the off-season， and the shipment of some specifications has improved. However， the trading atmosphere in the small and medium-sized pipe market is still cold， it is expected that the market price of Cangzhou seamless pipe will be stable and weak in the near future.
If you want to make the copper surface become bright again， you can polish it with copper point solution. It can not only make the copper surface brighter， but also quickly remove the rust and oxide layer on the copper surface to restore the luster of the copper itself.
