Insert the pipe into the top of the bayonet,e the sleeve on the pipe to evenly apply the flux on the joint, then wipe off the excess flux, and the joint is assembled and can be heated.The blowing mouth of the welding tool should not be too small to avoid excessive concentration of heat.Rostock,Many people do not fully understand the storage method of copper tubes in the process of use and production methods.The price of pig iron market rose by - yuan this week,Rostock15CrMo alloy steel plate, and the transaction was fair. With the increase of coke price, 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, the price of iron foundries rises again.Kumi,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.At the opening this morning, the market price of Zhengzhou copper bar was basically stable. 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 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, 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, 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.

Red copper plate has ductility. Pure copper, which is as big as a drop of water can be pulled up to two kilometers of thin wire or rolled into a transparent foil larger than a bed. The most valuable property of red copper row is that it has a very good conductive , second onlyver in common metals. But copper is much cheaper than silver, so it has become the & quot; protagonist& quot; of the electrical industry.As theation effect of copper material on the agent is weak, the dissolved oxygen and air bubbles in it will corrode it.When welding, just add enough filler metal to fill the capillary gap. Too much filler metal will only form a ball at the bottom of the joint or run into the pipe.safety requirements ,The second of the five application fields of red copper plate T, red copper row and red copper tube: copper is widely used in the chemical industry to manufacture vacuum vessels, brewing pots, etc.In addition, it is not easy to be corroded and can adapt to various environments. It can be used normally at low and high temperatures, so copper pipes need to be selected for many times in other places.The blowing mouth of the welding tool should not be too small to avoid excessive concentration of heat.

Remove the flame. If the filler metal does not melt, continue to heat the joint and try again. The melted filler metal is sucked into the casing port according to the capillary effect until a complete filler metal ring appears on the casing port. Remove the flame Pay special attention not to let the flame directly contact the filler metal. It should be the heat at the joint that melts the filler metal. In order to clean the copper pipe, the welding flux must have a degree of corrosivity, and shall be cleaned after brazing. The so-called & quot; self-cleaning& quot; fluxes are generally not recommended because of their corrosivity.Customer first,The composite method of three production methods of copper tube is also a high-tech production method for this method. It is a copper material containing impurities. Those copper materials, copper alloys and composite copper materials are put together by electrochemical reaction to produce a nanocrystalline copper material, and then the material is purified to produce copper tube materials.The storage and transportation of copper tubes in summer should also be paid attention to when controlling the surface of copper tubes.Disadvantages: low output, high production cost and high price. Extrusion copper tube process is a stable and excellent copper tube production method at home and abroad at present. Only the copper tubes produced by this process are more suitable for the field of heating and ventilation, which is the development direction of copper tube industry in the future.Rostock,The main force of iron ore futures closed at in The closing price of the day today was the same as that of the previous trading day including * * * * , * * * , settlement price , trading volume , and position volume . The intraday tradg volume decreased by compared with the previous trading day, and the position volume decreased by compared with the previous trading day. After six consecutive days of downward adjustment, there was a rebound at the bottom of the session today, but it was corrected again later and the closing was flat.Although the opening continued the weak trend, the intraday transactions improved, and the prices of some copper bar manufacturers rose. From the specific situation, although the manufacturer feedback that the shipment is average, the mentality is relatively calm, the market inventory is not much,Rostockcopper Stick,Rostock201 stainless steel plate, and the manufacturer is not willing to significantly reduce the price. In terms of the market, the transaction of strip steel is better than other steel varieties, and the downstream mainly focuses on callback buying without panic inventory clearing. It can be seen that although the steel market continues to shake, the overall demand for strip steel remains in a good state.The application of copper tube The copper tube is generally used in the heat exchange equipment, and the low-temperature pipeline in the oxygen production equipment can also be used. Some relatively thin copper tubes can be used to transport some pressurized liquids, and can also be used as pressure measuring tubes in instruments; In addition, the copper pipe is relatively firm, unlike other metals, which are easily corroded, so now many water pipes and refrigeration pipes used in buildings will choose to use the copper pipe.
