Q:Can aluminum plastic pipes be used for solar energy pipes?
Can, but must pay attention to the inner tube of plastic pipe material shall be PEX or PERT, is usually orange (or orange), ordinary white plastic pipe inside the PE material, can only be used in the 40 degrees below the water.
Q:Can 6061 aluminum tubes be bent?
6061 of the aluminum tube can bend. It does not harden for a long time.You can bend it with a pipe bender. You should choose a slightly larger bend radius when you choose the radius of the curve.As a kind of high strength aluminum tubes, can be strengthened by heat treatment, annealing, quenching and heat under the condition of rigid plasticity, good welding, gas welding and argon arc welding in aluminum has the tendency of intergranular crack formation; aluminum hardening in quenching and cold after the cutting performance is good, bad in annealing state. The corrosion resistance is not high, in order to improve the corrosion resistance of anodic oxidation treatment and often used methods of paint or aluminum surface layer. Can also be used as a die material.
Q:Will the size of the aluminum tube become smaller after oxidation?
Will aluminum tubes become smaller after oxidation? Or after the oxidation section factory again suppressed shaping? Arguably, aluminum oxidation texture should become loose, profile factory should also be a set of professional solutions to deal with the possible problems in the deformation of metal products processing, but also should have their own set of data and tolerance of quality control and evaluation... If he can not control the oxidation number of products lead to invalid they can only say, technology has not yet reached the precision products...
Q:Air conditioning copper aluminum tube is good?
The use of copper aluminum tube is due to copper prices in recent years is too high, the adoption of cost reduction measures, the use should be little difference, compared to pure copper pipe is better.
Q:I would like to invest in this line of production.
Sapa heat transfer (Shanghai) Co., Ltd. pipe division any electrical engineer, project and process engineer, technical director, proficient in German sholar welding pipe production line, welding of various high-frequency tubes (flat tube, rectangular tube, pipe) technology and equipment are very fine, well versed in the world's most advanced tubes (especially thin-walled aluminum tubes, wall thickness of 0.20-0.32mm) welding technology.
Q:How to obtain hollow aluminum tubes such as drawings by rolling?
The length can be rolled, but must be the middle groove turning or milling.Chasing the answerThe pipe wall is thin and the requirement of accuracy is not high. The rough car will do. The precision requirement is high, so the numerical control car will be needed!AskBut how thin is the lathe?Chasing the answerIn copper, three claw clamping, after the car, and then cut to the required length.
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:What is the difference between the extrusion process of seamless aluminum tubes and conventional aluminum tubes?
The short rod, high temperature, slow extrusion process, especially to control the "three temperature", aluminum rod, extrusion cylinder, and the mold must be kept clean, aging time and temperature are adjusted according to the wall thickness of a size of it
Q:What happened to the mold sticking when drawing the aluminum pipe? How do you make the mold?
1. apply mold release agent on the mold.2. the necessary taper shall be taken into account in the design of the die.3. punch opening and exhaust hole.4. charging and discharging device.5. improve the mold finish.6. mold surface treatment of titanium.The main purpose of the mold surface treatment is to improve the surface hardness, wear resistance and corrosion resistance, etc., so as to improve the quality of mold products, and extend the service life of the die. Reasonable application of surface treatment technology to obtain high precision mold surface is the necessary condition of high precision and good surface quality products. The cost of the surface strengthening process is lower, but the service life of the die can be improved by 5~10 times or even several times, and the economic benefits are obvious.According to the present application status of China's mold surface treatment technology, I published by the user survey found that, at present, surface treatment technology of mold manufacturing enterprises mainly used or in surface hardening, carburizing / traditional nitrogen technology, electroplating and chemical plating technology, and these technologies have varying degrees of surface hardness distribution all the heat treatment deformation and other aspects of the problem difficult to solve. For the future technological transformation, the common concern is the application of new technologies, such as surface coating technology, TD coating treatment technology, laser surface strengthening technology and electron beam strengthening technology. Below we specially invited several industry technical experts, respectively, the user's attention to these deep into the discussion, and hope to benefit the general mold enterprise technical upgrading.
Q:Unique aluminum plastic pipe and folder tubes which do Kaitai warm water pipe is better?
Italy Ke Yi's pure import aluminum plastic composite pipe is good. In Europe, with imported Swiss good, ground heating pipe is a competitor.
