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.
Disadvantages 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， the cost of copper pipe is much higher and the connection at the copper pipe interface requires high construction technology level.

In 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， there was no unilateral market for either futures or cash it can be seen that at this stage， 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 and that of B steel is yuan/ton; Jiyuan # yuan/ton， B steel yuan/ton; Fulen # yuan/ton; Weigang # yuan/ton， 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，술 룩321 스테인리스강 권재， 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， 적동배출 it should be said to maintain a relatively moderate level.
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.

Generally， 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.

생산 원가The price of pig iron market rose by - yuan this week， and the transaction was fair. With the increase of coke price， the cost of ductile iron in Shanxi， Henan， Shandong and other regions has increased. In addition， with the gradual release of downstream demand， the inventory of iron plants is not large， and iron plants have successively raised their prices. There are few iron foundries in Shandong， Jiangsu， Hebei and Shanxi， and the inventory remains low. As the coke price rises and the cost increases， the price of iron foundries rises again.
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.
In view of the current overall price difference， the local copper bar price continued to rise at a high level today， while the regions outside East China did not show an obvious follow-up trend， and the local price still has the advantage of price difference with the Northeast and Central China regions. The local inventory pressure will be further reduced due to the small volume of local follow-up goods under the influence of production restriction， and the price support of copper bar is still strong. However， at present， domestic real estate control is still being tightened. The markets expectation of future demand is weakening， and the markets fear of heights appears after the price rises.Today，술 룩201 스테인리스 강판， the market price of copper bars in Shenyang is stable and the shipment is poor.

Disadvantages: Due to loose tissue and high pressure resistance， the pipe is only used to produce small air conditioning copper rods.
술 룩The 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， 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， 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.
The price of tube billets was adjusted and lowered mainly due to the production restriction of environmental protection and the weak demand for temperature and weather. Recently， the terminal demand has also shrunk due to the sudden drop in temperature， causing a weak shock. According to the communication with local traders in Cangzhou， various good news last week led to the shipment of thermal expansion pipes in Cangzhou in the past two weeks， which is better in the off-season， and the shipment of some specifications has improved. However， the trading atmosphere in the small and medium-sized pipe market is still cold， and the demand is slowing down gradually. To sum up， it is expected that the market price of Cangzhou seamless pipe will be stable and weak in the near future.
The market opened today. Although the performance of Zitong Pai futures was modest， the overall market has stopped. The market mentality has not changed much sincekend. The price is stable， but some specifications are subject to negotiation， and the negotiation range is about - yuan. The overall rhythm of the market is stable and cold. In the middle of winter， the overall market in Northeast China has entered the traditional off-season， and the overall market has ended with little improvement. All companies are selling goods. The inventory level in Shenyang is very low due to the inventory clearing， and all construction sites have been closed. In addition to the transportation pressure brought by the low temperature， the market was bleak.
