구리 표면의 부식이 경미한 것으로 발견되면 리넨 동선으로 지울 수 있지만 기름을 발라 방부하는 것은 권장되지 않는다.
The hard copper tube is not artificially treated after being drawn or extruded， 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.
요 로.Heat and insert the copper tube and sleeve， and move the flame nozzle back and forth continuously between two points. Do not touch the flame directly with the flux. When heating steel pipes， the temperature is slightly higher than when heating copper pipes.
Advantages and scope of application of copper tube ground heating At present， ground heating is not only a comfortable heating method， but also a symbol of modern life quality. More and more houses， public buildings， sports facilities， industrial facilities and other places begin to use ground heating radiator， which is an important part of ground heating. Due to the corrosion resistance of copper， copper tubes are selected as the main material of radiator in many places.

The difference between hard copper tubes and soft copper tubes in use Hard copper tubes can only be used as straight tubes and cannot be bent. Therefore， they are generally used in power plants， switches of electrical equipment， and places where the connection points are far away and do not need to be bent. Compared with soft copper tubes， the price of hard copper tubes will be lower. Although the name of the soft copper tube is soft tube， it can also be used as a hard tube， so the soft copper tube is used in more places， and can be used in a straight tube way， asell as in a coiled tube way. The length of the copper tube can be longer if the coil is used. If the connection point is longer， it can be cut randomly according to the length， so as to prevent leakage when welding the copper tube. Soft copper pipes are used in many refrigerators， air conditioners and other places where bending pipes are needed. When we use copper， we need not consider the preservation problem unless we buy a small amount at home. For example， large manufacturers use copper units to buy a large number of copper pipes once， so there will be a problem. I believe some people do not know how to store unused copper materials Now lets ask our staff to introduce the storage method of copper for you.

또한 쉽게 부식되지 않으며 다양한 환경에 적응할 수 있습니다.그것은 저온과 고온에서 정상적으로 사용할 수 있기 때문에 다른 곳에서는 여러 번 동관을 선택해야 한다.
불순한 구리 재료로 인한 부식.
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， T， oxygen free copper plate (TU， TU and high-purity， vacuum oxygen free copper) deoxidized copper plate (TUP， TUMn) 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， sea water， some non oxidizing acids， alkalis， salt solutions and a variety of organic acids (aic 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，요 로.1060 알루미늄 바， the output value of copper plate exceeded that of other copper alloys.
제일 싸다Generally， 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.
Lets elaborate on the advantages of copper pipe materials: copper pipe floor heating refers to a heating method that uses hot water as the thermal medium， circulates in the copper pipe heating pipe， heats the floor， the service life of the floor heating tube will not be affected. Two. Copper pipe is a metal pipe，o it is not easy to scratch. Therefore， it is not easy to leak. Three. High temperature resistance， high pressure resistance， relative to any ordinary plastic pipe. Copper tube floor is warm and resistant to high temperature and pressure. Four. Long service life. Five.
It has excellent conductivity， thermal conductivity， ductility and corrosion resistance.
먼저 구리 파이프를 가열하고 용접한 다음 이음매를 가열하여 가열된 부분이 진홍색으로 변할 때까지 가열합니다. 이때 충전 금속이 파이프와 접촉할 때 충전 금속은 용해되어야 합니다.

동관은 견고하고 부식에 견디는 특징을 가지고 있어 수도관， 난방관과 냉동관 설치의 첫 번째 선택이다.
그것은 우수한 전도성， 열전도성， that is， the annealing process is added compared with the hard copper tube. Annealing of copper tubes means that they are calcined in a high temperature furnace to change the arrangement of the elements in the copper tubes. However， after annealing， the copper tubes will become soft，요 로.6061 알루미늄 바， which makes it easier to bend. The copper tubes produced in this way are called soft copper tubes.
또 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.
In addition， it is not easy to be corroded and can adapt to various environments. It can be used normally at low and high temperatures， so copper pipes need to be selected for many times in other places.
