The blowpipe shall be perpendicular to the lead pipe during welding， and the flame shall be moved continuously to prevent local overheating and the flux from carbonizing before filler metal is added.
The price of pig iron market rose by - yuan this week， and the transaction was fair. With the increase of coke price，알 룬 달12Cr1MoV 합금 강판，알 룬 달316L 스테인리스 강판， the cost of ductile iron in Shanxi， Henan， Liaoning， 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.

Red copper inventory may end the trend of continuous decline. With the increase of production restriction of steel enterprises and the pressure of demand the continuous decline of iron ore port inventory may end. In addition， the available days of imported iron ore of steel mills are days according to the new statistics of * *， 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 iron ore inventory basically meets the production requirements. Considering the future production reduction and restriction， the steel mill is not willing to replenish the inventory.
탐 블 리 어The material of the water separator is the same， the expansion coefficient is the same， and the connection with the water separator is not easy to leak. Scope of application: As the copper pipe is more expensive than the plastic pipe， the cost of the floor heating system is higher.
용접 공구의 드라이어는 열이 지나치게 집중되지 않도록 너무 작아서는 안 된다.
If the corrosion on the copper surface is found to be slight， it can be erased with linen copper wire， but it is not recommended to apply oil for preservation.
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， molds， heat exchangers， pumps， etc.

추천 하 다.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， it should be said to maintain a relatively moderate level.
쌓을 때는 합리적으로 쌓고 우선적으로 놓아야 한다.
After the pipe is cleaned，알 룬 달H65 황동판， 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.
월에 국내 중후판 가격이 대폭 하락했다.월 일까지 주요도시의 일반탄소판가격센터는 이미 으로 내려가 월말에 비해 톤당 원 하락했다.이달 초， the overall order receiving quantity of Tianjin Hebei Henan Plate Plant was not ideal. According to the monitoring data， the overall order intake of medium and heavy plate mills in Tianjin Hebei Henan region in the first ten days of May remained stable and weak. Due to the weak market shock， the overall order intake of the spot steel market was relatively weak. The total quantity of orders received in the first ten days of May is only about tons， while at the end of April， the total quantity of post settlement agreements of main steel plants can exceed tons.

However， it is difficult to change this situation too much in the short term. It is expected that the domestic strip steel price will mainly rise in the short term. It is reported that in order to pursue profits Tangshan Iron and Steel Group Co.， Ltd. is currently increasing the supply of hot coils. It does not rule out that more steel mills in the future are inclined to one end of the plate in pursuit of profits， or to lay hidden dangers for the decline. As far as tomorrow is concerned， the price may still maintain a narrow range of shock operation pattern.
알 룬 달Five of the five major application fields of copper plate copper bar and copper tube: copper is used in medicine. In the s， Chinese medical inventors Liu Tongqing and Liu Tongle found that copper has extremely strong s， and successfully developed the corresponding "Cancer Suppressing "， which is successful in the near future.
