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.Heat and insert the copper tube and sleeve, and move the flame nozzle back and forth continuously between two points. Do not touch the flame directly with the flux.The production method of soft copper tube is basically the same as that of hard copper tube, that is, the annealing process is added compared with the hard copper tube. Annealing of copper tubes means that they are calcined in a high temperature furnace to change the arrangement of the elements in the copper tubes. However, after annealing, the copper tubes will become soft, which makes it easier to bend. The copper tubes produced in this way are called soft copper tubes.equipment maintenance ,Chantaburi304 stainless steel plate,The blowpipe shall be perpendicular to the lead pipe during welding,ChantaburiAlloy steel, and the flame shall be moved continuously to prevent local overheating and the flux from carbonizing before filler metal is added.The price of tube billets was adjusted and lowered mainly due to the production restriction of environmental protection and the weak demand for temperature and weather. Recently, the terminal demand has also shrunk due to the sudden drop in temperature, causing a weak shock. According to the communication with local traders in Cangzhou, various good news last week led to the shipment of thermal expansion pipes in Cangzhou in the past two weeks, which is better in the off-season, and the shipment of some specifications has improved. However the trading atmosphere in the small and medium-sized pipe market is still cold, and the demand is slowing down gradually. To sum up, it is expected that the market price of Cangzhou seamless pipe will be stable and weak in the near future.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 blowing mouth of the welding tool should not be too small to avoid excessive concentration of heat.market,After the pipe is cleaned, so that dust and dirt will not pollute the capillary gap.In buildings with continuous heating water supply a lot of corrosion and pitting occur on heating water pipes.Advantages: good quality, fine structure, high density, 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.Chantaburi,Disadvantages: Due to loose tissue and high pressure resistance, the pipe is only used to produce small air conditioning copper rods.I don t know how to keep the copper tube.The price of tube billets was adjusted and lowered mainly due to the production restriction of environmental protection and the weak demand for temperature and weather. Recently, causing a weak shock.
