일반적으로 산소아세틸렌을 기원으로 사용하고 액화석유가스 용접도구를 사용하여 가열한다.용접 도구의 용접봉은 이음매를 향하고 계속해서 전체 이음매를 가열해야 한다.이것은 과도한 국부 가열을 피할 것이다.
용접할 때는 모세관 간격을 채우기 위해 충분한 필러 금속을 추가하기만 하면 됩니다.너무 많은 채우기 금속은 조인트 하단에만 구를 형성하거나 파이프로 유입됩니다.
빈 가 빈 항합격된 구리 원료를 사용하여 생산하고 가능한 한 재생 구리로 생산된 파이프를 사용하지 않으며， 불순물의 부식을 줄이고， 구리 파이프의 사용 수명을 연장한다.
자동관의 장점 내구성: 구리는 안정적인 화학재산을 가지고 있으며 내한， 내압， 내부식과 내화를 일체화하여 서로 다른 환경에서 장기적으로 사용할 수 있다.
안 토 니 오 에 니 시Three 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.
우선， 우리는 창고를 하나 세워야 한다.창고 내의 온도는 보통 - & deg로 유지해야 한다.C. 습도는 정상이어야 합니다.방은 통풍을 유지해야 한다.
It has excellent conductivity， thermal conductivity， ductility and corrosion resistance.
When welding， just add enough filler metal to fill the capillary gap. Too much filler metal will only form a ball at the bottom of the joint or run into the pipe.
단점: 파이프 구조가 느슨하고 고압에 약하다.그것은 소형 에어컨 동관 생산에만 적용된다.
구리 재료의 저장 방법에 대해 말하자면， 우리는 우리가 구입한 구리 제품을 잘 보관하고， 구리의 사용 수명을 연장하며， 그 성능을 확보하여 불필요한 손실을 피해야 한다.
항목 을 분석 하 다Disadvantages of copper pipe As far as copper pipe is concerned， high production cost and high price are its biggest disadvantages. Compared with other pipe fittings， the cost of copper pipe is much higher， and the connection at the copper pipe interface requires high construction technology level.
The conductive production of copper tube is the latest method for this method. It is the production of nanocrystalline copper materials with conductivity. Because this raw material is very special， it is a copper material produced by using nanotechnology，빈 가 빈 항304L 스테인리스 강판， and copper ions can be separated by conductivity， so that copper tubes can be produced with the separated copper ions. This method is very complex， requires high technology and new equipment， so only advanced foreign countries can use this production method.
The price of pig iron market rose by - yuan this week， and the transaction was fair. With the increase of coke price the cost of ductile iron in Shanxi， Henan， Liaoning， Shandong and other regions has increased. In addition， with the gradual release of downstream demand， the inventory of iron plants is not large， and iron plants have successively raised their prices. There are few iron foundries in Shandong， Jiangsu， Hebei and Shanxi， and the inventory remains low. As the coke price rises and the cost increases， the price of iron foundries rises again.
Safe and reliable: copper pipe combines the advantages of metal pipe and non-metal pipe. It is harder than plastic pipes and has the high strength of ordinary metals (the strength of cold drawn copper pipes is equivalent to that of steel pipes with the same waess); It is also easier to bend than ordinary metals， has good toughness and high ductility，빈 가 빈 항321 스테인리스강 원강， and has excellent anti vibration， anti impact and anti frost expansion properties.

In order to solve these problems， silicon containing welding wires are commonly used in welding， because silicon will form a layer of dense silicon film on the surface of the molten pool， which will hinder the evaporation of zinc and prevent the invasion of hydrogen.
Generally， oxygen aylene is used as the gas source and LPG welding tool is used for heating. The torch of the welding tool shall face the joint and then continuously heat the whole joint. This will avoid excessive local heating.
빈 가 빈 항The application of copper tube The copper tube is generally used in the heat exchange equipment， 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.
After the pipe is cleaned， 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.
The ex factory price of Linyi Pipe Factory has decreased by yuan for cash Baocheng ( * mm， the same below) yuan， yuan for Ruigang Lianlian， yuan for Baoda yuan， yuan for Meixin yuan， and yuan for Taizong yuan.
