Hygiene and health: various modifiers， additives， additives and other chemical components of plastic pipes in copper pipes.
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，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.

방습지로 싸서 방습을 보호할 수 있다.그것은 또한 어느 정도 산화를 방지할 수 있다.균열이 발견되거나 심하게 부식되면 반드시 격리시켜야 한다.
나 쁜 ISchlIn terms of steel billets: at :， some steel billets in Changli were reduced by ， and the current carbon square billets were delivered with tax of yuan. After the th National Congress of the Communist of China， it can be seen that at this stage， there was no unilateral market for either futures or cash， and there was no definite pattern of ups and downs.According to the monitoring data of Lange Iron and Steels cloud business platform， as of the time of publication， Tianjin Youwelded Line: the steel mill reported: Rongcheng # yuan/ton， B yuan/ton; Jiujiang # - # to Tianjin yuan/ton; The arrival price of Xinji Aosen # is yuan/ton，반 휘304 스테인리스 강판， and that of B steel is yuan/ton; Jiyuan # yuan/ton， B steel yuan/ton; Fulen # yuan/ton; Weigang # yuan/ton B steel yuan/ton.
동관의 세 가지 생산 방법은 동관이 동재료의 매우 중요한 재료라는 것을 개술한다.이런 동관의 생산을 완성할 수 있는 많은 방법이 있다.구리 파이프의 경우 일반적으로 다음 세 가지 방법을 사용하여 재료를 생산합니다.이 세 가지 방법으로 생산된 동관은 성능이 매우 좋을 뿐만 아니라 조작도 매우 편리하다.동관은 세 가지 생산 방법이 있는데 동관의 세 가지 생산 방식은 무엇입니까?
단점: 생산량이 낮고 생산 원가가 높으며 가격이 높다.압출 동관 공예는 현재 국내외의 안정적이고 우수한 동관 생산 방법이다.오직 이런 공예로 생산한 동관만이 난방분야에 더욱 적합하며 이는 동관업종의 미래의 발전방향이다.
It is said that due to the optimistic future and tight resources， some iron plants do not take orders temporarily. The steel mills in Liaoning have increased their enthusiasm for purchasing steel. The iron mills have delivered well， so the iron price has risen. The iron mills have a high enthusiasm for producing steel， so there is not much cast iron resources and the price has risen. A few steel mills in Tangshan began to purchase a small amount of steel for smelting， and most steel mills are still on the lookout for inquiry. Under the background of increasing cost and gradual release of demand， the pig iron market is performing well and is expected to continue to operate strongly in the short term.
조각된 구리 파이프의 생산 및 가공의 경우 판금 작업장에서 일반적으로 개구라고 하는 도면과 같은 크기로 판금을 먼저 열어야 합니다.그런 다음 모서리의 높이에 따라 이러한 개구부 조각의 모서리를 가공한 다음 배관 절곡 기계를 사용하여 용지 성형 도면의 모서리를 만듭니다.성형동관은 또 요구에 따라 강화근을 설치해야 하며 성형판의 사각은 잘 용접해야 한다.용접 부품을 연마 작업장으로 보내 스프레이 표면을 연마하고 용접 인터페이스를 평평하게 다듬는다.광택을 낸 조형 구리 파이프는 도포 작업장에 보내 가공한다.도포하기 전에 조각된 동관의 표면은 크롬 도금 처리를 하고 공예 구멍을 뚫어 조각된 동관이 도포선에 잘 매달릴 수 있도록 해야 하며， 도포가 매끄럽고 흐르는 흔적이 없으며， 색깔이 일치하고 색차가 없다.이후 고객 요구에 따라 적격제품을 보호막을 부착하고 기포막이나 나무상자로 묶는다.
For small diameter pipes， when using filler metal， the length of filler metal is allowed to be equal to the diameter of the pipe， which is enough to fill the weld crater. One of the five major application fields of red coppr plate T， red copper bar and red copper tube: copper is the most widely used and used in the electrical and electronic industries， accounting for more than half of the total consumption. Used for various cables and wires， motors and transformers， switches and printed circuit boards; In the manufacture of machinery and transport vehicles， it is used to manufacture industrial valves and accessories， instruments， sliding bearings，반 휘빨간 동봉， molds， heat exchangers， pumps， etc.
얼마 면 돼?At present the fundamentals faced by the domestic copper bar market are still mixed. On the one hand， the market supply is expected to shrink， but on the other hand the northern market has entered the off-season of demand， and the markets expectation of future demand is pessimistic. In the short term， domestic steel prices will enter the operating track of range consolidation. To sum up， considering the current situation of demand and inventory in the steel market， it is difficult for the steel market to make a breakthrough. As the th National Congress of the Communist of China is approaching， and black series speculation is still taking place. But personally， and businesses can operate flexibly on a short-term basis， and the shipment transaction is * * *.
Copper tube is a kind of nonferrous metal tube， which is pressed and drawn seamless tube. The copper pipe has good thermal conductivity， and is solid and corrosion resistant. It will not crack when compared with the ambient temperature， so it becomes the first choice for modern contractors to install the water pipe， heat supply pipe and refrigeration pipe in all residential commercial houses.
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 access of vehicles is alicted. The port collection and distribution vehicles are prohibited from entering and leaving the port area. 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. After : on October ， the vehicle enterprises in the above industries will implement % of the peak load shifting emission reduction measures. It is estimated that the average daily consumption of sintering powder in Tangshan will be more than yuan， 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.
압출법: 본 생산 방법은 정련 후 구리 주괴를 주조하고 차 가열 후 대형 압출기로 구리 파이프를 압출한다.
작업 원가단점: 조직이 느슨하고 고압에 강하기 때문에 이 파이프는 소형 에어컨 동봉 생산에만 사용된다.
Copper pipe has the characteristics of firmness and corrosion resistance， and is the choice for the installation of water pipe， heating pipe and refrigeration pipe.
The production method of soft copper tube is basically the same as that of hard copper tube， 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， which makes it easier to bend. The copper tubes produced in this way are called soft copper tubes.
반 휘In August， the price of domestic medium and heavy plates fell sharply. As of August ， the price center of ordinary carbon boards in leading cities had dropped to ， down yuan/ton from the end of July. At the beginning of the month， affected by the macro bad news， and the recent poor performance of fundamentals，반 휘7075 알루미늄 막대， the market mentality turned to pessimism， and some traders shipped at low prices. The market inventory rose， the inventory pressure was high， the stock shortage phenomenon disappeared， and the market transaction atmosphere was cold， the demand performance continued to decline， and the spot price fell under pressure.
