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.Generally, oxygen aylene is used as the gas source and LPG welding tool is used for heating. The torch of the welding tool shall face the joint and then continuously heat the whole joint. This will avoid excessive local heating.Carlton Ville,After welding, it can be annealed at ~ ℃ to prevent & quot; self cracking& quot; by stress.Advantages: good quality, fine structure, high density,Carlton Ville304 stainless steel plate, high pressure resistance, large bending deformation, suitable for frequent cold and heat exchange large temperature difference in working environment, and large size copper tube can be produced.Pak Kret,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.Five of the five major application fields of copper plate, copper bar and copper tube: copper is used in medicine. In the s, and successfully developed the corresponding & quot; Cancer Suppressing & quot;,Carlton VilleGCR15 alloy round steel, which is successful in the near future.Four of the five major application fields of copper plate, pipe fittings and decorative devices in the construction industry.

Do not store too many other products, in the warehouse to prevent mutual reaction.The storage and transportation of copper tubes in summer should also be paid attention to when controlling the surface of copper tubes.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, according to the new statistics of * *, the available days of imported iron ore of steel mills are days, 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.Credit guarantee,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.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,Carlton Ville6061 aluminum tube, which are easily corroded, so now many water pipes and refrigeration pipes used in buildings will choose to use the copper pipe.Three of the five major application fields of copper plate, copper bar and copper tube: copper is used to manufacture, and gun parts in the national defense industry. Every million rounds of copper are produced, - tons of copper are needed.

The conductive production of copper tube is the latest method for this method. It is the production of nanocrystalline copper materials with conductivity. Because this raw material is very special, it is a copper material produced by using nanotechnology, and copper ions can be separated by conductivity, so that copper tubes can be produced with the separated copper ions. This method is very complex, requires high technology and new equipment, so only advanced foreign countries can use this production method.quality index,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.The more residual chloride ions, the deeper the corrosion pit of water.Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.Carlton Ville,First of all, while the humidity should be normal. The room should be kept ventilated.Do not store too many other products, especially other acid materials and alkali materials, in the warehouse to prevent mutual reaction.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.
