After : on October ， continue to implement the measures of stopping and limiting production specified in TZBZ [] No. document. All sintering machines and shaft furnaces using wet desulphurization in iron and steel enterprises in the city were shut down， and sintering machines using semi dry desulphurization continued to be shut down for %. The access of vehicles is alicted. The port collection and distribution vehicles are prohibited from entering and leaving the port area. The citys steel， coking， cement，아부 다비6063 알루미늄 바， chemical and other key vehicle enterprises are not allowed to transport vehicles into and out of the plant. After : on October ， the vehicle enterprises in the above industries will implement % of the peak load shifting emission reduction measures. It is estimated that the average daily consumption of sintering powder in Tangshan will be more than yuan， and the purchase of iron ore may still maintain a small amount of prudence. In addition， due to the influence of industrial users "coal to gas"， the recent performance of coke is weak. Therefore， in terms of steel plant production， the support of raw materials is weak.
Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.
아부 다비It is applicable to the removal of thin liquid oil stain and light rust and the generation of phosphating film with certain corrosion resistance. See Table for example of formula and operating conditions. Table Degreasing， rust removal， phosphating and passivation
Insert the pipe into the top of the bayonet，e the sleeve on the pipe to evenly apply the flux on the joint and confirm that the pipe is inserted into the bottom of the socket， then wipe off the excess flux， and the joint is assembled and can be heated.
말 두antages: low production cost and high production efficiency.
장 & # ;우리는 동관 재료의 장점을 상세히 서술했다: 동관 지온은 뜨거운 물을 열매체로 이용하여 동관 가열관에서 순환하고 바닥을 가열하며， 지면을 통해 복사와 대류 전열 방식으로 바닥을 가열하는 일종의 가열 방법을 말한다.. 동관은 열을 방출하는 효과가 빠르고 내열성이 강하다.고온으로 물을 공급하는 상황에서도 지온관의 사용 수명은 영향을 받지 않는다.둘동관은 금속관이고，o 잘 안 긁혀요.따라서 누설은 쉽지 않다.셋고온에 강하고 고압에 강하며 어떤 일반 플라스틱 파이프에 비해도.동관 바닥은 따뜻하고 고온과 고압에 강하다.사수명이 길다.다섯
The blowing mouth of the welding tool should not be too small to avoid excessive concentration of heat.
구리 표면의 부식이 경미한 것으로 발견되면 리넨 동선으로 지울 수 있지만 기름을 발라 방부하는 것은 권장되지 않는다.
It mainly refers to strengthening the research on copper pipe corrosion and formulating a complete and scientific copper pipe use plan.
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.
특혜The market price of Zhengzhou copper bars is basically stable， and the shipment is not good. In terms of tube blank: today， Shandong Luli tube blank slightly reduced by yuan， and the current mainstream ex factory price is - yuan. In terms of pipe plant: Linyi Pipe Plant locked the price for a week. With a stable market mentality， the factory price of hot rolled seamless pipes is now between - yuan. On the market side: with the arrival of the off-season， traders generally ship goods at a high price. Replenishment is mainly to maintain the existing inventory， and there is no large replenishment plan. The demand is sluggish， and the market price of Zhengzhou copper bar is expected to be stable and declining.
In view of the current overall price difference， the local copper bar price continued to rise at a high level today， 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，아부 다비201 스테인리스 강판， and the markets fear of heights appears after the price rises.Today， the market price of copper bars in Shenyang is stable and the shipment is poor.

아부 다비In 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.
Copper pipe has the characteristics of， and is the choice for the installation of water pipe， heat supply and refrigeration pipe.
With the advent of heating season， steel mills in some regions began to implement the production restriction measures for blast furnaces in heating season， and the demand for iron ore was weakened. In addition， the production restriction policy was issued in Tangshan today. From : on October to : on October ， the production restriction measures specified in this Notice were implemented.
