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， and has excellent anti vibration anti impact and anti frost expansion properties.
Four 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.

In the middle and late ten days although there were good news such as the rise of futures and the increase of production restriction policy in Wuan region， traders had no desire to increase prices， most of them had shipped goods， and spot prices lacked motivation to rise. The market inventory rose significantly. At that time， the market inventory in Handan reached a high level after the festival. The sluggish demand performance for a long time led to the oversupply of the market， and the continuous rise of inventory led to the empty market mentality.

만약 당신이 장기적으로 이런 상황을 피하고 싶다면， 당신은 둔화 처리를 선택할 수 있다.이렇게 하면 구리 표면이 심할 뿐만 아니라 정상적인 상태에서는 청결할 수 있지만 초음파 처리와 침포 처리 후 년 이상 공기 중에 유지하는 것은 큰 문제가 아니기 때문에 이런 효과가 매우 좋다.
After : on October ， continue to implement the measures of stopping and limiting production specified in TZBZ [] No. document. All sintering machines and shaft furnaces using wet desulphurization in iron and steel enterprises in the city were shut down， and sintering machines using semi dry desulphurization continued to be shut down for %.

The citys steel， coking， electric power， cement， chemical and other key vehicle enterprises are not allowed to transport vehicles into and out of the plant.

It is estimated that the average daily consumption of sintering powder in Tangshan will be more than yuan，메 인 강변 프랑 크 푸 르 트6063 알루미늄 바， and the purchase of iron ore may still maintain a small amount of prudence. In addition due to the influence of industrial users "coal to gas"， the recent performance of coke is weak. Therefore， in terms of steel plant production， the support of raw materials is weak.

With the advent of heating season， the raw material support of red copper row is weak. Under the influence of heating season and environmental protection production restriction， steel mills in some regions began to implement the production restriction measures for blast furnaces in heating season，메 인 강변 프랑 크 푸 르 트6061 알루미늄 바， and the demand for iron ore was weakened. In addition， the production restriction policy was issued in Tangshan today. From : on October to : on October ， the production restriction measures specified in this Notice were implemented.
품질 이 향상되다.Remove the flame. If the filler metal does not melt， continue to heat the joint and try again. The melted filler metal is sucked into the casing port according to the capillary effect until a complete filler metal ring appears on the casing port. Remove the flame Pay special attention not to let the flame directly contact the filler metal. It should be the heat at the joint that melts the filler metal. In order to clean the copper pipe， the welding flux must have a degree of corrosivity， and shall be cleaned after brazing. The so-called "self-cleaning" fluxes are generally not recommended because of their corrosivity.
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， 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.

조회 하 다.The production method of soft copper tube is basically the same as that of hard copper tube， that is， after annealing， the copper tubes will become soft， which makes it easier to bend. The copper tubes produced in this way are called soft copper tubes.
