압출법: 본 생산 방법은 정련 후 구리 주괴를 주조하고 차 가열 후 대형 압출기로 구리 파이프를 압출한다.
According to * * new data， in September ， Chinas imported iron ore * * * broke through the million ton mark， reaching million tons， a record high; From January to September， Chinas 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，빅토리아알루미늄판， which is likely to decline further in the future.
빅토리아When the PH value of water is lower than ， it will cause acid corrosion to the copper wall.
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， molds， heat exchangers， pumps， 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.
구리 표면을 다시 밝게 만들고 싶다면 구리 점 용액으로 광택을 낼 수 있다.그것은 구리 표면을 더 밝게 할 뿐만 아니라 구리 표면의 녹과 산화층을 빠르게 제거하고 구리 자체의 광택을 회복 할 수 있습니다.
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?
당산강판이 지난 주말에 대폭 상승하여 일부 북방도시의 강철공장이 생산제한을 실시하였고 일부 국내경제수치가 다소 개선되였는데 이는 제조업체의 신심을 진작시켰다.믿음오늘날 강재 가격이 보편적으로 상승하고 있다.그러나 회의가 다가오고 태풍으로 인한 남쪽의 비가 내리면서 하류 공사장의 공사 진도가 영향을 받아 지속적인 수요에 불리하다.고현물 가격 거래이 지역 시장의 평가 범위는 제한되어 있으며， 기업은 단기간에 유연하게 경영할 수 있으며， 선적 거래는 * * * 이다.
Try to avoid using radiator copper pipes in hot water circulation pipelines to reduce the possibility of corrosion. If copper pipes are used as circulation pipelines， pipeline maintenance space should be reserved.
Although the opening continued the weak trend， 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.

In the morning trading today， the price of domestic copper bar fell. According to the monitoring data of Lange Steels cloud business platform， the average price of * mm hot rolled strip in key cities in China is ， down yuan from yesterday. Futures prices fluctuated， and the prices of spot market manufacturers eased slightly today. According to the feedback， the market was mainlysee yesterday，빅토리아황동판， which caused the overall transaction blocked， and the mainstream manufacturers prices fell today.
Do not store too many other products， especially other acid materials and alkali materials in the warehouse to prevent mutual reaction.
동관의 단점은 동관의 경우 높은 생산 원가와 높은 가격이 가장 큰 단점이다.다른 파이프 부품에 비해 구리 파이프의 원가가 훨씬 높고 구리 파이프 인터페이스의 연결은 비교적 높은 시공 기술 수준을 요구한다.

방습지로 싸서 방습을 보호할 수 있다.그것은 또한 어느 정도 산화를 방지할 수 있다.균열이 발견되거나 심하게 부식되면 반드시 격리시켜야 한다.
빅토리아또한 쉽게 부식되지 않으며 다양한 환경에 적응할 수 있습니다.그것은 저온과 고온에서 정상적으로 사용할 수 있기 때문에 다른 곳에서는 여러 번 동관을 선택해야 한다.
개장과 함께 약세 흐름을 이어갔지만 일내 거래가 개선돼 일부 동봉 제조업체의 가격이 올랐다.구체적인 상황을 보면， 비록 공장이 출하량이 보통이라고 피드백했지만， 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.
