The simplest way is to use copper cleaner. Brass, red copper, bronze, etc. can be used. Oil stains, fingerprints, oxide layers, etc. on the surface can be cleaned with copper cleaner first.When stacking, it shall be stacked reasonably and placed first.Leverkusen,When heating steel pipes, the temperature is slightly higher than when heating copper pipes.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.Vila Franca de Xira,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,LeverkusenQ345D alloy round steel,Leverkusen316L stainless steel coiled plate, 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 * * *.In the first ten days of May, 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.Today, the price of tube billets is up and down. At present, Jiangxin hot rolling is yuan continuous casting yuan is down yuan, Dongfang hot rolling yuan is down yuan, Luli hot rolling yuan is down yuan, Tiangang hot rolling an is down yuan, Weigang hot rolling yuan is up yuan, continuous casting yuan is up yuan, Huaigang yuan is up yuan, Zhongtian yuan, Changqiang yuan, Linggang yuan.

The market opened today. Although the performance of Zitong Pai futures was modest, the overall market has stopped. The market mentality has not changed much sincekend. The price is stable, but some specifications are subject to negotiation, the overall market in Northeast China has entered the traditional off-season, and the overall market has ended with little improvement. All companies are selling goods. The inventory level in Shenyang is very low due to the inventory clearing, and all construction sites have been closed. In addition to the transportation pressure brought by the low temperature, it is often used in some ah heat exchangers to Kazakhstan oxygen equipment.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.Good reputation,In Jiangyin market, another distribution center, the overall inventory of the current circulation link is about tons, slightly lower than the normal level. At the beginning of this week, the price gap between Jiangyin prices and those in the north has also been able to correspond to the slightly lower circulation inventory. However, from the perspective of the policy port of the steel plant the overall production situation of Nangang, Hengrun, Dada etc. is relatively normal, and the amount of resources in the later period remains stable. The overall inventory of Lecong market remains at about to tons, which is a medium normal level, and the recent spot price of Lecong market has a large gap with that of the north.The excellent performance of copper pipe The copper pipe has the characteristics of and, which makes it a suitable choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial housing.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.

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.Energy costs,Save materials and total cost, stability and performance,LeverkusenGCR15 alloy round steel, and can save maintenance.In buildings with continuous heating water supply, a lot of corrosion and pitting occur on heating water pipes.Insert the pipe into the top of the bayonet,e the sleeve on the pipe to evenly apply the flux on the joint, and confirm that the pipe is inserted into the bottom of the socket, then wipe off the excess flux,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.Tangshan billets rose sharply last weekend, steel mills in some northern cities implemented production restriction, and some domestic economic data improved, which boosted manufacturers confidence. Today, steel prices generally rose. However, 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.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.
