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 excellent performance of copper pipe The welded copper pipe has the characteristics of firmness and corrosion resistance, which makes it a suitable choice for modern contractors to install the water pipe, heating pipe and refrigeration pipe in all residential commercial houses.Some steel mills in Liaoning are interested in purchasing pig iron, but the local resources are tight, and the iron mills quotations are on the high side, resulting in a stalemate between supply and demand. The demand for cast iron and ductile iron in Jiangsu, Shandong, Shanxi, Hebei Henan and other regions is sluggish, and the inventory pressure of iron mills is increasing. As the price of raw materials decreases, the quotation of iron mills continues to decline. At present,Awb ā r ībrass tube, the demand and cost support are weak, and there is no positive boost. The short-term pig iron market is weak and difficult to change.Quality inspection report,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.In the morning trading today the price of domestic copper bar fell. According to the monitoring data of Lange Steel s cloud business platform, the average price of * mm hot rolled strip in key cities in China is , down yuan from yesterday. Futures prices fluctuated,Awb ā r ībrass plate, and the prices of spot market manufacturers eased slightly today. According to the feedback, the market was mainlysee yesterday, which caused the overall transaction blocked and the mainstream manufacturers prices fell today.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 market s 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, environmental protection phenomena such as steel mills are still going on, and black series speculation is still taking place. But personally, the fluuation range of the market in this region is limited, and businesses can operate flexibly on a short-term basis, and the shipment transaction is * * *.
The copper tube shall be heated and welded first, and then the joint shall be heated until the heated part turns dark red. At this time, when the filler metal contacts the tube, the filler metal shall melt.High value,It can be wrapped with moisture-proof paper for moisture-proof protection. It can also prevent oxidation to a certain extent. If cracks or serious corrosion are found, the pipe is only used to produce small air conditioning copper rods.Awb ā r ī,Because of the characteristics of copper itself, it is very easy to rust and corrode in places with high ambient humihumidity. If we often use it, the problem will be smaller, but if it is placed for a long time, the copper will be damaged. Many people do not know how to treat the copper surface? Now let the staff answer for you.It can be wrapped with moisture-proof paper for moisture-proof protection. It can also prevent oxidation to a certain extent. If cracks or serious corrosion are found, they must be isolated.To sum up, due to the influence of factors such as the current spot market price is much higher than the expected winter storage price of merchants, the gradual emergence of supply and demand pressure, and the weakness of raw material support, among which the contraction of market demand has a greater impact. Therefore, the author believes that in the short term, the spot building materials do not have the possibility to rise significantly, and the price of building materials may mainly operate in shock, the supply and demand pressure becomes prominent, However, considering the influence of winter storage and other factors, it is still possible for merchants to lower the spot price in November.
