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， 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.
수복 하 다구리 자체의 특성으로， 환경 습도가 높은 곳에서는 녹이 슬고 부식되기 쉽다.습도우리가 자주 사용하는 경우 문제가 더 적지만 오래 두면 구리가 손상됩니다.많은 사람들이 구리 표면을 어떻게 처리하는지 모릅니까?이제 직원이 답변해 드리겠습니다.
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.
For small diameter pipes， the length of filler metal is allowed to be equal to the diameter of the pipe，라 이언.청동판， 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，라 이언.316L 스테인리스 강판， 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， molds， heat exchangers， pumps， etc.

How to preserve the copper tube? In order to protect the excellent performance of copper pipes from the impact of the environment we need to do the following: First， select appropriate sites and warehouses， and keep the surrounding environment dry and ventilated. Do not stack together with acid， alkali， salt， cement， etc.
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.

According to the monitoring data of the Lange cloud business platform， the current market price of * mm Linyi copper bar was yuan (ton price， the same below)， the * mm copper bar was yuan， and the * mm copper bar Henan copper bar was yuan. Red copper inventory may end the trend of continuous decline. With the increase of production restriction of steel enterprises and the pressure of demand， according to the new statistics of * *， the available days of imported iron ore of steel mills are days， which is one day lower than that before the National Day and is on the high side of history. The steel mill said that at present， the steel mill is not willing to replenish the inventory. Tangshan billets rose sharply last weekend the iron ore inventory basically meets the production requirements. Considering the future production reduction and restriction， steel mills in some northern cities implemented production restriction， and some domestic economic data improved， which boosted manufacturers confidence. Today， with the approaching meeting and the rainfall in the south caused by the typhoon， the construction progress of the downstream construction site is affected， which is not conducive to the continuous demand. The high spot price transaction today is weak， which is difficult to support the continuous rise of steel prices. It is expected that the building materials market will maintain a volatile trend tomorrow， and some businesses may reduce prices and take goods.
