Q:About the import and export of aluminium pipe 50
Hello, I have a product introduction to see if I can help you with this problem. The main uses of this product are. 1 、 water based organic pore sealing agent is a kind of product in organic sealing treatment process. It uses the charge action of some polar groups of organic fat, and soon adsorbed on the surface of the film to form a sealing protective film. Experiments show that the sealing film has anti fingerprint, anti greasy dirt and self purification.2, this product can replace all kinds of solvent baking sealing products, suitable for all kinds of metal products over long period of rust prevention, aluminum has a good sealing effect. And for the metal copper, alloy steel, stainless steel, steel and other metal materials have excellent adhesion and anti rust properties; for lamps, metal crafts, fine locks, car and motorcycle accessories, such as electroplating tank hardware antirust bright decoration etc..
Q:Which friend has the national standard about seamless copper tube and aluminium tube, some help to send, very grateful, urgent!

Q:Seamless tubes and welded aluminum performance is what is the difference between
In the case of aluminum tubes of the same material:1, seamless aluminum pipe can be used for fluid parts, such as: water stamping, air, hydraulic, machining, grinding and other important parts.
Q:Why is copper pipe used instead of copper aluminum composite tube or aluminium pipe?
Generally, there are dimension indexes, inner diameter, outer diameter and wall thickness.Strength index, pipe strength indicators have radial compressive strength, that is, ring stiffness, flexibility index, bending index, impact strength, etc.For drinking water pipes, there are technical aspects of health indicators, as well as water pressure indicators.For the communications industry, there are other technical requirements.
Q:Can anodized aluminum 6061-T6 surface be oxidized?
The so-called T6 is a kind of heat treatment, the main process is rolling solid solution and aging, these steps is to let the inner Aluminum Alloy changed, the metal can reach high strength and long deformation, anodic oxidation of our workpiece can have better conductivity and not the impurity content of workpiece the 6061 is too high, a low impurity content of his aluminum alloy aluminum is much less than, so the conductivity of aluminum has good ductility and high anodic oxidation and chemical polishing, is a good choice.
Q:Haier refrigerator is now using aluminum tube material,
The aluminium material used in refrigerator is because:Aluminum costs lower prices.Now the processing of aluminum tube material (such as molding, surface oxidation treatment, copper aluminum joints, etc.) have reached a relatively advanced level.In the assembly design, are basically installed in a relatively hidden and protected place.
Q:Who has good refrigerator, aluminum tube butt joint method, welding technology?. Thank you
I can weld the copper tube and the aluminum tube, but I'm not sure I can make it clear. Pipe butt welding to argon arc welding, in the middle two aluminum tubes with a brass copper aluminum welding, because just a little bit more simple.
Q:Which pressure is high between titanium tube and aluminium tube?
It depends on how to compare, pure titanium tube or titanium alloy tube? Pure aluminum tube or aluminium alloy tube? Titanium alloys and aluminium alloys are divided into many grades.
Q:Will the aluminum tube (6063) anodized after the local needle hole shaped point, what is the reason for it, is the material problem or oxidation plant corrosion?
You are the light, or the fog, if light, are certainly no oxidation treatment, that is, if the surface is like fog, that is normal.
Q:What is the difference between the aluminum tube connection and the copper tube connection of the air conditioner?
Links are used almost, but the effect of the. Copper is high cost, good ductility, resistance to oxidation, bellbottom do good pressure resistance, not easy leakage of refrigerant, disadvantage is high cost, use for a long time will be aging hard aluminum biggest advantage is cheap, and good bending and bending resistance than copper, we all know that when we installed air conditioning, pipeline is often there is no need to bend the copper tube bending resistance, the cooling effect will not be affected, but the disadvantage is that the pressure difference can not do bell, not resistant to oxidation, it is prone to leak, if not good insulation cotton, it is a hidden danger. Now the beautiful GREE is using copper tubes.
