I dont know how to keep the copper tube.

In Jiangyin market， another distribution center， the overall inventory of the current circulation link is about tons， slightly lower than the normal level. At the beginning of this week， the price gap between Jiangyin prices and those in the north has also been able to correspond to the slightly lower circulation inventory. However， from the perspective of the policy port of the steel plant， the overall production situation of Nangang， Hengrun， Dada， etc. is relatively normal， and the amount of resources in the later period remains stable. The overall inventory of Lecong market remains at about to tons， which is a medium normal level， and the recent spot price of Lecong market has a large gap with that of the north.

Red copper bars in other regions basically follow the price trend of Tangshan， in which the bid of Jiangsu Steel Works tends to be higher， and most of the downstream prices are asked， and the overall market transaction is fair. The steel mills in Wuan are limited in receiving orders， and the market resources are tight. Most of the merchants are reluctant to sell. Shanxi billet market offers vary， and it is difficult to clinch a deal. The willingness of downstream customers to receive orders is weak， so they hold a cautious wait-and-see attitude. At prepresent， the steel market is in the "golden third" peak season. The market has a good expectation of the future market and a strong willingness to support prices. It is expected that the prices of Tangshan mainstream billets will be stronger next week.
Advantages: good quality， fine structure， high density， high pressure resistance， large bending deformation， suitable for frequent cold and heat exchange， large temperature difference in working environment， and large size copper tube can be produced.
When placing， they should be stored separately according to the different components， and should not be mixed together. The copper surface may have electrolytes， so it will react， especially with other materials such as rubber， which has a large impact.
합격된 구리 원료를 사용하여 생산하고 가능한 한 재생 구리로 생산된 파이프를 사용하지 않으며， 불순물의 부식을 줄이고， 구리 파이프의 사용 수명을 연장한다.
When stacking， it is very easy to rust and corrode in places with high ambient humihumidity. If we often use it， the problem will be smaller， but if it is placed for a long time， characterized by light weight， good thermal conductivity， high low-temperature strength and corrosion resistance. Because of these excellent properties of copper tubes the use of copper tubes is very common. What are the differences between hard copper tubes and soft copper tubes in the use process? What are the differences between the two in terms of specific applications?

추천 컨설팅[] 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.

Red copper inventory in key areas has risen continuously， but the total pressure is not big. From the current overall inventory situation of the main distribution centers Wuan， Jiangyin and Lecong， the inventory level remains relatively moderate， and the pressure on the market is relatively small. In Wuan market， according to the data， as of May ， the total inventory of medium and thick plates in Wuan was close to tons， increasing by tons on a weekly basis. In late April， it reached tons lower in the year， down tons from the high level after the Spring Festival， and rose for three consecutive weeks. In terms of the ovquantity， it should be said to maintain a relatively moderate level.
천진The 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，천진복합 동갈비， the copper pipe is relatively firm， unlike other metals， so now many water pipes and refrigeration pipes used in buildings will choose to use the copper pipe.
Extrusion method: This production method is to cast copper ingots after smelting， and extrude copper tubes by large extruder after secondary heating.
