Q:Seamed tubes and seamless tubes under which good?
A pipe is better than pressure welded aluminum tube, seamless aluminium pipe texture is relatively uniform, there will be a small amount of loss in the part of the chemical composition of weld, so the mechanical properties of poor and seamless, but not big difference.Two, if the elbow pipe would recommend the use of seamless pipe, easy to crack, the bending radius is large enough no problem, that is because although there is high frequency welded pipe welding seam, but it is a composite aluminum tube, which is composed of Aluminum Alloy material more than 2, its surface layer for brazing layer.Three, aluminum tube refers to the use of pure aluminum or aluminum alloy extrusion processing into its longitudinal length of hollow metal tubular material. There may be one or more closed through holes with uniform wall thickness and cross section to be delivered in a straight or coiled form. Widely used in automobiles, ships, aerospace, aviation, electrical appliances, agriculture, machinery and electrical, home and other industries.1, according to the shape of: square tube, round tube, pattern tube, special-shaped tube;2, according to extrusion method: seamless aluminum tube and ordinary extrusion pipe;3, according to precision points: ordinary aluminum tube and precision aluminum tube, in which the precision aluminum tube generally needs to be processed after extrusion, such as cold drawn, fine drawn, rolling;4, according to thickness points: ordinary aluminum tube and thin-walled aluminum tube.Four: Performance: corrosion resistance, light weight.Five, aluminum tubes are widely used in all walks of life, such as: automobiles, ships, aerospace, aviation, electrical appliances, agriculture, electrical and mechanical, home, etc., aluminum pipe in daily life has been everywhere.
Q:What causes aluminium tubes to peel and blacken?
This phenomenon is common when the aluminum pipe is connected with other metals and has electrolyte liquid flow. This is because the electrochemical reaction forms the galvanic cell. Aluminum is the anode, and the surface of the aluminum tube is oxidized to cause blackening and peeling
Q:How can I check the refrigerator for copper tubes,
Generally speaking, the refrigerator pipeline system is divided into high pressure section and low pressure section,From the compressor outlet to dry filter high pressure section, a condenser, a dew proof tube, filter composed of high pressure pipe, the high pressure section is from capillary tube; to press the return pipe low pressure, low pressure with capillary, evaporator, an air return pipe, capillary and return tube are used for copper pipe, evaporator aluminum and iron, but the economic crisis since the price of copper fell, some manufacturers in order to improve product quality and increase the selling point, but also the use of copper tube evaporator, refrigeration evaporator mounted in the installed freezer, said separating rack, plastic drawer on the shelf, you can try to remove Pakistan drawer, copper general refrigeration evaporator buried device in a cabinet, we cannot see.
Q:What is the extrusion process of aluminium tube?
Process flow is:Billet heating, hot extrusion, cutting, boring, wagon, wool two heating, extrusion, tension or straightening roller leveler, cutting chuck - intermediate annealing, corrosion, inspection, repair, scraped the cold rolling, annealing, quenching, stretching, heading to the whole diameter, straightening, cutting and finished product sampling artificial aging, annealing, inspection and acceptance, oiling and packing
Q:Can aluminum tube and aluminium plate be welded? Fifty
The aluminum plate drilling ahead, just put the tube into the principle, and then argon arc welding
Q:How to weld the refrigerator aluminum tube?
Flame brazing of aluminium tube for refrigerator.Because the refrigerator aluminum tubes are relatively small, relatively thin, and more used for copper tube, aluminum pipe or aluminum pipe copper pipe welding, of course, there are aluminum pipe, aluminum pipe welding. From the above three situations, can be divided into the following welding methods1, if it is aluminum brass or brass tubes connected, can choose Wei Odin copper aluminium welding rod flame brazing welding, the welding work at the melting point of 480 degrees, is cored electrode without the use of complex welding powder.2, if it is connected to the aluminum tubes, aluminum welding can be used WEWELDING Q303, with no need to use liquefied petroleum gas spray welding powder, heating WE53 special welding parts to 500 degrees, and then use the wire in welding parts with a wire tip forming flame burn slightly. Can also use ordinary ER4047 aluminum wire with aluminum powder to WE53-F welding, the welding cost is relatively low, but the technique requirements are relatively high. For expert use.
Q:The difference between aluminium pipe and galvanized steel pipe
The aluminum surface has a layer of oxide film, melting point at more than 2000 degrees, and the melting point of aluminum is only about 400 degrees. Galvanized sheet is a sheet of zinc plated on sheet iron or carbon steel.
Q:Can 6061 aluminum tubes be bent?
6061 of the 1.5, if the bend, you have to heat up a try. Too hard! With gas roast roast
Q:How long can the air conditioning aluminum tube take?
Three or four years!! We usually do it here. We need to replace it with copper tubes...
Q:How can aluminum tubes be processed into circles? Five
Rounding machine ah ~ no words can help me you do! I have several sets of rolling machine! The pipe is well made! Your satisfaction is guaranteed.
