작은 지름 파이프의 경우 금속 채우기를 사용할 때 용접 구덩이를 채울 수 있을 만큼 길이가 파이프의 지름과 같을 수 있습니다.홍색과학보급 대 응용령역의 하나r 보드 T， 적동 막대 및 적동 파이프: 구리는 전기 및 전자 산업에서 가장 널리 사용되며 전체 소비량의 절반 이상을 차지합니다.다양한 케이블 및 전선， 모터 및 변압기， 스위치 및 인쇄 회로 기판에 사용됩니다.기계 및 운송 차량의 제조에서 산업 밸브 및 부품， 계측기， 슬라이딩 베어링， 몰드， 펌프 등을 제조하는 데 사용됩니다.
It is mainly used to manufacture electrical devices such as generators， buses， cables， switchgear， transformers and thermal conductive devices such as flat plate collectors for heat exchangers， pipes， and solar heating equipment. Common copper alloys are divided into three categories: brass， bronze and white copper. Pure copper plate is a purplish red metal， commonly known as "copper plate"， "red copper plate" or "red copper plate".
화려 하고 아름답다.Corrosion caused by water with high chloride ion content.
구리 표면의 부식이 경미한 것으로 발견되면 리넨 동선으로 지울 수 있지만 기름을 발라 방부하는 것은 권장되지 않는다.
카 펜 버그일 중후반， 예를 들면 선물 가격 상승과 무강 생산 제한 정책이 증가한다;한 지역에서는 재고 수준이 매우 높기 때문에 무역상들이 가격을 인상할 의사가 없으며， the expansion coefficient is the same and the connection with the water separator is not easy to leak. Scope of application: As the copper pipe is more expensive than the plastic pipe， the cost of the floor heating system is higher.
This week (-， the market price of red copper bar rose and the transaction was not ideal. On the bidding day of Shagang last weekend， the price was stable to support the market， and the rising of billets at the weekend drove the market up in a wave， and the price of variety wire rods also rose by yuan at the weekend. However， it was reported that the deal was very poor， which led to the price being stable for the next two days. Until Wednesday， due to the negative outlook on the future market and the reduction of steel billets in the afternoon spiral diving， the market lowered the price. Market price changes， Xinji rose yuan on the rd; For the future market，화려 하고 아름답다.6061 알루미늄 바， the off-season is coming， the demand is weakening， and the market wait-and-see mood is getting stronger. But when winter comes， the environmental protection inspection is becoming more and more strict， which supports the market. It is expected that the price ofety wire rod will be adjusted in a weak way in the short term.
Among the three production methods of copper tube， the oxidation method is the most. Because as long as the metal copper is oxidized by the anode and the copper ion of the anode is attached to the tube material， the copper tube can be produced. Thisthod is also the most common method to produce copper materials. It has not only been used for a long time， but also has a mature technology， which is to produce copper tubes through oxidation reaction. This production method is the main production method of copper tubes in China.
구리 파이프와 튜브를 가열하여 삽입하고 두 점 사이에서 연속적으로 화염 노즐을 왔다갔다합니다.용접제로 화염에 직접 접촉하지 마라.
Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.
오퍼 를 내다.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.
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， 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，화려 하고 아름답다.빨간 동봉， 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，화려 하고 아름답다.2205 스테인리스 강판， B steel yuan/ton; Fulen # yuan/ton; Weigang # yuan/ton， B steel yuan/ton.
Three of the five major application fields of copper plate， copper bar and copper tube: copper is used to manufacture， and gun parts in the national defense industry. Every million rounds of copper are produced， - tons of copper are needed.
However， 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.
