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，라 스 팔 마 스7075 알루미늄 튜브， the overall production situation of Nangang， 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.
개장과 함께 약세 흐름을 이어갔지만 일내 거래가 개선돼 일부 동봉 제조업체의 가격이 올랐다.구체적인 상황을 보면， 비록 공장이 출하량이 보통이라고 피드백했지만， 심리 상태는 상대적으로 평온하고， 시장 재고가 많지 않으며， 공장도 큰 폭의 가격 인하를 원하지 않는다.시장면에서 대강거래는 기타 강재품종보다 우월하며 하류는 주로 회수매입을 위주로 하며 공포성재고정리가 없다.이로부터 알수 있는바 강재시장이 지속적으로 요동치고있지만 대강의 전반 수요는 여전히 량호한 상태를 유지하고있다.
라 스 팔 마 스When installing， the copper pipe has the advantages of low transportation cost， easy maintenance and small space occupation.
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.
만.The room temperature tensile strength of the annealed red copper sheet is ~ kgf/mm， the elongation is ~%， and the Brinell hardness (HB) is ~
Copper tube is also called copper tube nonferrous metal tube. It is a pressed and drawn seamless pipe， characterized by light weight， good thermal conductivity， high low-temperature strength and corrosion resistance. Because of these excellent properties of copper tubes， the use of copper tubes is very common. What are the differences between hard copper tubes and soft copper tubes in the use process? What are the differences between the two in terms of specific applications?

When cutting the copper pipe of air conditioner， use tools such as clamps to fix the copper bar and then cut it， rather than fixing it by hand， the cut parts need to be placed in a dry place， and then processed again after cooling， otherwise oxidation will occur due to high temperature. Liu Shuchen， director of the Resource Analysis Office of the Information Center of the Ministry of Land and Resources， said that copper bar manufacturers are currently in a period of adjustment in Chinas mining industry as a whole. In the long run， the mining super cycle driven by Chinas demand has not changed， especially the growth rate of the countrys economy. After the global economy may improve in the second half of the year， the global mining industry will rise again， and the W-shaped trend will fully emerge. In the second half of the year， there were signs of stabilizing and rebounding. In terms of the macro factors affecting the bulk commodities， the factors affecting the European market of tinned copper bars have gradually weakened， and the economic conditions of China and the United States have become the key factors affecting the bulk commodities. The European economic recession is a foregone conclusion， and the possibility of a crisis in the next period of time is also reduced. In recent years， the American market economy has shown the characteristics of better than expected in the first quarter and weaker than expected in the second quarter. Since January， the global price of medical copper tubes has gradually got rid of the main tone of this years shock and decline. "Air conditioning copper tubes show signs of stabilizing and rebounding. The three-month copper on the London Metal Exchange once rebounded nearly % from the years low point， and the market price has rebounded to around dollars per ton. Driven by this， products including aluminum， zinc and other products have also rebounded. Only nickel， has remained weak.

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， and the price support of copper bar is still strong. However， at present， the market price of copper bars in Shenyang is stable and the shipment is poor.
Later， Mexican scientists also found that copper has a . Recently， British researchers found that copper has a strong bactericidal effect. It is believed that in the near future， copper will make great contributions to improving human health. Copper plate T is named after its purple color. It is not necessarily pure copper， sometimes it also involves a few deoxidizing elements or other elements to improve raw materials and s， so it is also included in copper alloys. The processed materials of Chinese cor plate can be divided into four categories according to the composition: ordinary copper plate (T， T，라 스 팔 마 스201 스테인리스 강판， T， T， oxygen free copper plate (TU， TU and high-purity， vacuum oxygen free copper)， deoxidized copper plate (TUP， and special copper plate (arsenic copper， tellurium copper， silver copper) with a few alloy elements added. The conductivity and thermal conductivity of copper plate are second only to silver， and are widely used to manufacture conductive and thermal conductive devices. The red copper belt has outstanding corrosion resistance in the atmosphere，라 스 팔 마 스주석 도금 적동 막대， sea water， some non oxidizing acids alkalis， salt solutions and a variety of organic acids (aic acid， citric acid)， and is used in the chemical industry. In addition， the red copper plate has outstanding weldability and can be made into various semi products and products through cold and thermoplastic processing. In the s， the output value of copper plate exceeded that of other copper alloys.
Extrusion method: This production method is to cast copper ingots after smelting， and extrude copper tubes by large extruder after secondary heating.
재무 부The 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.
위의 두 가지 유형의 열 연결은 일반적으로 "용접"이라는 용어를 사용합니다. 이 두 경우 용접된 용접물은 설치할 두 기기의 깨끗하고 긴밀한 고체 금속 표면의 좁은 간격에 기록되기 때문입니다.
수분 분리기는 재료가 같고 팽창 계수가 같아 수분 분리기와의 연결이 잘 새지 않는다.적용 범위: 구리 파이프가 플라스틱 파이프보다 비싸기 때문에 난방 시스템의 비용이 더 높습니다.
라 스 팔 마 스또 다른 집산지인 강음시장에서 현재 유통단계의 전체 재고는 약 만 톤으로 정상 수준보다 약간 낮다.이번 주 초 강음 가격과 북방 가격 간의 가격 격차도 약간 낮은 유통 재고에 대응했다.그러나 제철소 정책항을 보면， 남강， 항윤， 다다 등 전체 생산 상황은 비교적 정상이며， 후기 자원량은 안정을 유지한다.락종시장의 전반 재고는 만~만톤 좌우를 유지하여 중등정상수준에 속하며 최근 락종시장의 현물가격은 북방과 비교적 큰 차이가 있다.
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.
