First of all, we should set up a warehouse. The temperature in the warehouse should be generally kept at - ° C, while the humidity should be normal. The room should be kept ventilated.This week (-, the market price of red copper bar rose, and the transaction was not ideal. On the bidding day of Shagang last weekend, the price was stable to support the market, and the rising of billets at the weekend drove the market up in a wave, and the price of variety wire rods also rose by yuan at the weekend. However, it was reported that the deal was very poor, which led to the price being s table for the next two days. Until Wednesday, due to the negative outlook on the future market and the reduction of steel billets in the afternoon spiral diving, the market lowered the price. Market price changes, the off-season is coming the demand is weakening, and the market wait-and-see mood is getting stronger. But when winter comes, the environmental protection inspection is becoming more and more strict, which supports the market. It is expected that the price ofety wire rod will be adjusted in a weak way in the short term.Thongwa ,Many people do not fully understand the storage method of copper tubes in the process of use and production methods.When placing, and should not be mixed together. The copper surface may have electrolytes, so it will react, especially with other materials such as rubber, which has a large impact.Budwa,Four of the five major application fields of copper plate, copper bar and copper pipe: copper is used as various pipes, pipe fittings and decorative devices in the construction industry.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.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 Wu an, Jiangyin and Lecong the inventory level remains relatively moderate, and the pressure on the market is relatively small. In Wu an market according to the data, as of May , the total inventory of medium and thick plates in Wu an was close to tons, it reached tons lower in the year, and rose for three consecutive weeks. In terms of the ovquantity, it should be said to maintain a relatively moderate level.

The ex factory price of Linyi Pipe Factory has decreased by yuan for cash Baocheng ( * mm, the same below) yuan, yuan for Jin Zhengyang yuan, yuan for Ruigang Lianlian, yuan for Baoda yuan, yuan for Meixin yuan, and yuan for Taizong yuan.As the inner wall of the pipe rubs with water, its film is damaged, resulting in erosion corrosion. The higher the water pressure, the greater the flow, and the more serious the corrosion.Save materials and total cost stability and performance, and can save maintenance.The cost is reasonable,The blowing mouth of the welding tool should not be too small to avoid excessive concentration of heat.When stacking, it shall be stacked reasonably and placed first.Advantages of red copper tube Durability: copper has stable chemical properties, integrating cold resistance, heat resistance, pressure resistance, corrosion resistance and fire resistance, and can be used in different environments for a long time.

Red copper bars in other regions basically follow the price trend of Tangshan,Thongwa 310s stainless steel round steel, in which the bid of Jiangsu Steel Works tends to be higher, and most of the downstream prices are asked and the overall market transaction is fair. The steel mills in Wu an are limited in receiving orders, and the market resources are tight. Most of the merchants are reluctant to sell. Shanxi billet market offers vary, and it is difficult to clinch a deal. The willingness of downstream customers to receive orders is weak, so they hold a cautious wait-and-see attitude. At prepresent, the steel market is in the & quot; golden third& quot; peak season. The market has a good expectation of the future market and a strong willingness to support prices. It is expected that the prices of Tangshan mainstream billets will be stronger next week.Process inspection,So far as the storage method of copper materials is concerned, we should properly keep the copper products we buy, extend the service life of copper and ensure its performance to avoid unnecessary losses.Brass tube Soft copper tube is called hose, and the tube is used to replace the hard one, so soft copper is widely used. Besides being in a straight line, you can also have coils and coils in the form of long advantages. When used at the connection point is long, cut according to the free length, so as to avoid leakage of copper tube brass welding. Soft copper tube requires local bending of air conditioner, refrigerator, and mechanical oil tube.pper tube Copper tube is easy to heat because of its light weight, and it can also be used normally at low temperatures.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.Thongwa ,For small diameter pipes, when using filler metal, 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, molds, heat exchangers, pumps, etc.The market opened today. Although the performance of Zitong Pai futures was modest,Thongwa Aluminum plate, the overall market has stopped. The market mentality has not changed much sincekend. The price is stable, but some specifications are subject to negotiation,Thongwa 12Cr1MoV alloy steel plate, 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 all construction sites have been closed. In addition to the transportation pressure brought by the low temperature, the market was bleak.Safe and reliable: copper pipe combines the advantages of metal pipe and non-metal pipe. It is harder than plastic pipes and has the high strength of ordinary metals (the strength of cold drawn copper pipes is equivalent to that of steel pipes with the same waess); It is also easier to bend than ordinary metals, has good toughness and high ductility, and has excellent anti vibration, anti impact and anti frost expansion properties.
