So far as the storage method of copper materials is concerned， we should properly keep the copper products we buy extend the service life of copper and ensure its performance to avoid unnecessary losses.

동관은 일종의 비철금속관으로서 압제하고 늘어나는 무봉관이다.동관은 열전도성이 뛰어나고 견고하며 부식에 강하다.환경 온도에 비해 갈라지지 않기 때문에 모든 주택 분양주택에 수도관， 난방관， copper alloys and composite copper materials are put together by electrochemical reaction to produce a nanocrystalline copper material， and then the material is purified to produce copper tube materials.
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.
Hot water accelerates the corrosion of copper pipes.
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.
검사 결과Disadvantages 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，타 마 르 코 현빨간 동봉， the cost of copper pipe is much higher， and the connection at the copper pipe interface requires high construction technology level.
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， and heats the floor through the ground in the form of radiation and convection heat transfer. I. The copper tube has fast heat dissipation effect and strong heat resistance. Even under the condition of high temperature water supply， the service life of the floor heating tube will not be affected. Two. Copper pipe is a metal pipe，타 마 르 코 현청동관，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.
The second of the five application fields of red copper plate T， red copper row and red copper tube: copper is widely used in the chemical industry to manufacture vacuum vessels， distillation pots， brewing pots， etc.
To sum up， the market in Northeast China is generally pessimistic based on the medium and long-term policies and the general environment， as well as the current inventory level in Shenyang. The low inventory level of copper platoon makes the whole market lack of motivation. The copper bar market in this city has stopped this year， and it is hard to improve in the short and medium term. On the whole， the market price of Shenyang copper bars may be stable tomorrow.

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.
타 마 르 코 현The simplest way is to use copper cleaner. Brass， red copper， bronze etc. can be used. Oil stains， fingerprints， oxide layers， etc. on the surface can be cleaned with copper cleaner first.
동관의 세 가지 생산 방법 중에서 산화법이 가장 많다.금속 구리가 양극에 의해 산화되고 양극의 구리 이온이 관 재료에 부착되면 구리 관을 생산할 수 있기 때문이다.여기방법도 구리 재료를 생산하는 가장 상용하는 방법이다.그것은 오랫동안 사용되었을 뿐만 아니라 산화 반응을 통해 구리 파이프를 생산하는 성숙한 기술이 있습니다.이런 생산 방법은 중국 동관의 주요 생산 방법이다.
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 the off-season is coming， and the market wait-and-see mood is getting stronger. But when winter comes， the environmental protection inspection is becoming more and more strict
