Q:Steel pipe can flange connection, aluminum pipe can flange connection? How about copper tubes?
The steel pipe, the aluminum tube and the copper pipe can be flanged connected.Flange connection is the two pipes, fittings or equipment, each first fixed on a flange plate, and between the two flange with flange pad, finally by bolt two flange of a detachable joint tension so closely together.purposeThis connection is mainly used for cast iron pipe, lining hose, non ferrous metal pipe and flange valve, etc., the process equipment and flange connection is also using flange connection.The main feature of flange connection is convenient disassembly, high strength and good sealing performance. When installing flanges, the two flanges shall be kept parallel and the sealing surfaces of flanges shall not be damaged and shall be cleaned. Gaskets used for flanges shall be selected according to design requirements.Connection modeFlange, threaded connection (wire), flange and welding flange. Low pressure small diameter wire connecting flange, high pressure and low pressure big diameter all use welding flange, different pressure flange thickness and connection bolt diameter and quantity are different.According to the different grades of pressure, the flange pad also has different materials, from the low pressure asbestos pad, high pressure asbestos pad and PTFE pad to metal pad all have.Flange connection, easy to use, able to withstand greater pressure.Flange flanges are widely used in industrial piping. In the home, the pipe diameter is small, and it is low pressure and can not see the flange connection. In a boiler room or production site, flanges are connected to pipes and equipment.
Q:What's the difference between a refrigerator and a copper tube?
Price。 The price of copper tube is higher than that of aluminium tube, so the cost of using all copper tube refrigerator will be raised greatly.Weight. Copper has a density greater than aluminum. Aluminum can reduce the weight of the refrigerator.Corrosion resistance. The corrosion resistance of copper is greater than that of aluminum. Aluminum tube in the sealed refrigerator, easy to be corroded by water and lead to refrigerant leakage, and copper corrosion resistance is stronger, unfavorable corrosion.Thermal conductivity. The heat conductivity of the copper tube is better than that of the aluminum tube, so the heat transfer effect of the refrigerator with the copper tube is good.Generally speaking, physical properties of copper is better than aluminum, but considering the cost factors, now basically do not use the refrigerator refrigeration system used in all aluminum tube, to make the refrigerator, only the key parts, such as capillary, compressor outlet for brass.
Q:We bought the house in 2008 Frestech refrigerator, 2 door, 179L, when the price is 1700 yuan. It's been four and a half years now. The refrigerator is broken. The refrigeration began to heat up in three hours, and the meat in the freezer became soft and soft. Call the customer service, please master home repair, the master told us that the cooling pipe corrosion leak, to add 450 yuan for copper pipe. Also said that after 2008 refrigerators produced, the basic cooling tube is iron or aluminum, in order to control costs. After the bad, you have to pay additional money to buy a new refrigerator, so as to update. Otherwise, like the previous refrigerator is copper tube, 20 years are not bad, manufacturers are unable to survive. Alas, are manufacturers today so black hearted?
Frestech refrigerator belongs to the second tier brands, with the greatest likelihood of iron pipe.At present, the domestic refrigerators are basically aluminum alloy tubes or iron pipes, the main reason is to reduce costs. In addition, the current refrigerant does not have any corrosive, and iron pipe is entirely possible.However, the exposed section, that is, the section of the compressor links, or copper tube, because it leaks in the air, the cold pipe will condense the moisture in the air, forming water droplets, if the iron pipe, it will rust easily. The main pipe is insulated by the insulation layer and is not in contact with the air. Therefore, the water pipe can not be collected, and the iron pipe is feasible.
Q:Why are copper tubes used in household air conditioners and aluminium tubes for automotive air conditioners?
The difference between the copper tube and the aluminum tube is mainly the price difference, and this difference is also very big.The use of aluminum tubes in air conditioning may result in the quality of aluminium and copper welds.
Q:What's the good quality of the aluminum tubes used for air conditioning?
1. pure copper has excellent ductilityAir conditioning has a tube expanding process in the manufacturing process, is put through the fin copper pipe burst, let bobbin and fin precision contact tube expanding technology is the key performance of heat exchanger of air conditioning, the ductility of copper to ensure good not easy in this process is broken.2. copper has an unparalleled corrosion resistanceCopper is much more resistant to corrosion than aluminum in the outdoor hostile environment. Statue of Liberty has been thinned since 1886 for more than 120 years, and that is proof of 0.127mm.4. in the joint place with copper and aluminum composite, two kinds of metal binding sites are likely to occur electrochemical corrosion potential of copper is +0.34V standard, standard potential of aluminum -1.28V, the potential difference between copper and aluminum is +1.62V. If direct contact between copper and aluminum, water in the air and carbon monoxide and other harmful impurities will form electrolyte on the contact surface of the joint, causing electrochemical corrosion, which is called galvanic cell.
Q:Aluminum pipe oval what reason?
The question is not clear and it is suggested to ask again
Q:What brand of aluminium tube is in freezer?

Q:Why is the copper tube of AUX air conditioning aluminum tube?
Copper tubes are often used as connecting pipes for air conditioners. Air conditioning aluminum tube is also a kind of non-ferrous metal pipe.

Q:Now a part of the connecting pipe of the air conditioner from the past to pure copper aluminum copper combined pipe, aluminum copper pipe is better seller says. Is it better in the end? Please help me professional fans.
Air conditioning connecting tube using copper and aluminum composite pipe is certainly not good, but cheaper.The connecting pipe of the copper aluminum composite pipe is an aluminum tube in the middle, and the copper pipe is welded at both ends, and there are several reasons for the bad:1, welding position is easy leaking and physical reaction.2, aluminum tube easy flat, fold.
