쌓을 때는 합리적으로 쌓고 우선적으로 놓아야 한다.
동관은 수도관， 난방관， 냉동관을 설치하는 것이 가장 좋은 특징을 가지고 있다.
오 모 크{} The excellent performance of copper pipe The welded copper pipe has the characteristics of firmness and corrosion resistance， which makes it a suitable choice for modern contractors to install the water pipe， heating pipe and refrigeration pipe in all residential commercial houses.
이번 주 양철 시장 가격은 - 위안 상승했으며 거래는 공정합니다.코크스 가격이 상승함에 따라 산시， 허난， 랴오닝， 산둥 등 지역의 잉크 주철 원가가 다소 증가하였다.이밖에 하류의 수요가 점차 방출됨에 따라 강철공장의 재고량이 크지 않아 강철공장이 륙속 가격을 인상했다.산동， 강소， 하북과 산서의 주철공장은 아주 적고 재고는 여전히 매우 낮다.코크스 가격이 오르고 원가가 증가함에 따라 주철공장의 가격이 다시 올랐다.
모터 로The hard copper tube is not artificially treated after being drawn or extruded， so that it can be naturally formed. At this time， the organizational form in the copper tube is full. This kind of copper tube is more likely to crack and is not suitable for bending. Therefore， the hard copper tube is generally straight.
[] Welding process of copper pipe Clean the end and seven ports of steel pipe with steel wool. Do not use abrasive cloth or abrasive paper to clean， because it will affect the clean interface and result in poor welding effect.
파이프를 청소한 후에는 즉시 인터페이스와 카드 사이에 용접제와 보조용접제를 발라야 한다.배합면에 충분한 용접제를 얇게 바르고 먼지와 때가 모세관 간극을 오염시키지 않도록 즉시 조립해야 한다.
To sum up， due to the influence of factors such as the current spot market price is much higher than the expected winter storage price of merchants， the gradual emergence of supply and demand pressure， and the weakness of raw material support，오 모 크201 스테인리스 강판， the author believes that in the short term， the spot building materials do not have the possibility to rise significantly， and the price of building materials may mainly operate in shock， but with the shrinking demand， the supply and demand pressure becomes prominent， However， considering the influence of winter storage and other factors， it is still possible for merchants to lower the spot price in November.
부식 가능성을 줄이기 위해 온수 순환 파이프에 라디에이터 구리 파이프를 사용하는 것을 최대한 피합니다.구리 파이프를 순환 파이프로 사용하는 경우 파이프 유지 보수 공간을 예약해야 합니다.
If the corrosion on the copper surface is found to be slight， it can be erased with linen copper wire， but it is not recommended to apply oil for preservation.
설비 유지 보수Save materials and total cost， stability and performance， 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， which are easily corroded so now many water pipes and refrigeration pipes used in buildings will choose to use the copper pipe.
그러나 단기간에 이런 상황을 바꾸기는 어렵다.당분간 국내 대강 가격이 주로 오를 것으로 예상된다.당산철강그룹유한공사는 이윤 추구를 위해 현재 열판관 공급을 늘리고 있는 것으로 알려졌다.앞으로 더 많은 제철소가 이윤을 추구하거나 하락의 위험을 묻는 경향이 있을 가능성도 배제할 수 없다.내일로 말하자면， 가격은 여전히 좁은 폭의 진동 운행 구도를 유지할 수 있다.
It has excellent conductivity， thermal conductivity， ductility and corrosion resistance.
견적서Today， the price of tube billets is up and down. At present， Jiangxin hot rolling is yuan continuous casting yuan is down yuan， Dongfang hot rolling yuan is down yuan， Luli hot rolling yuan is down yuan， Tiangang hot rolling an is down yuan， production is stopped in mid January， Weigang hot rolling yuan is up yuan， continuous casting yuan is up yuan， Huaigang yuan is up yuan， Zhongtian yuan，오 모 크알루미늄관， Changqiang yuan， Linggang yuan.
After welding， it can be annealed at ~ ℃ to prevent "self cracking" by stress.
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， etc.
오 모 크Four of the five major application fields of copper plate， copper bar and copper pipe: copper is used as various pipes， pipe fittings and decorative devices in the construction industry.
Disadvantages: Due to loose tissue and high pressure resistance， we should properly keep the copper products we buy extend the service life of copper and ensure its performance to avoid unnecessary losses.
