8mm copper tube condenser condenser drain oil-free pneumatic brass Aerospace

Custom processing: No Model: 8mm Size: 8 (mm) Material: Copper Usage: phosphorus deoxidized copper can be used in refrigeration and air conditioning, heat exchangers, radiators, cylinder head gasket and other purposes. The brass used as a gasoline or gas pipes, drains, cold brand: Aerospace due to the special nature of this baby, is supported by the requirements of buyers cut by the meter cut by jin said, it must be before buyers communication job, so they do not communicate directly shot refuse the shipment! If there is no quality problems, will not be returned, Thank you for understanding. So baby are semi-finished products, the surface scratches or abrasions, please be careful. * For buyers please inform the customer, price negotiable! Brass hard, difficult to corrosion, and high temperature, high pressure, can be used in a variety of environments. In contrast, many of the shortcomings of other pipes is obvious, such as the last residential multi-galvanized brass, easy to rust, not a long time there will be running water yellow, water and other smaller issues. Some material strength at high temperatures will rapidly decrease will have hidden dangers when used for hot water pipes, and the copper melting point of 1083 degrees Celsius, the temperature of the hot water system of copper pipes insignificant. Archaeologists found within pyramids of Egypt dating back 4500 years ago, copper pipes, still can use. Spec sheet copper brass weight formula, copper is copper: Copper was purple, also known as copper. Copper density is 8.96, melting point 1083 ℃, mass is calculated as follows: G = 8.96πδ (D-δ) / 1000 G: Quality kg δ: pipe wall thickness mm D: pipe diameter mm in line with the specifications of copper copper : weight per meter (kg) = 0.02796 * thickness * (OD - Wall Thickness) Type: Φ4 Φ6 Φ8 Φ10 Φ12 status: OL (light soft state) Sales unit: by the meter cut, by jin said, the entire disc sales , 1300-1600 m / disc (specific Advisory Service) production process: continuous casting, rolling process, pull triple combination with anti-resonance disc pull Alias: phosphorus deoxidized copper (TP2), R410A refrigerant tube, oil-free brass, brass refrigeration, air-conditioning brass Product Uses: mainly used for air conditioners, the master-mounted air-conditioning units, refrigerators, freezers, solar water heaters, fireplaces, etc. Product Features: This product has inner and outer surfaces of the high brass clean, ultra-bright, organization uniform and compact size, high precision, high heat transfer efficiency, easy welding, corrosion resistance, good formability use, each dish has suppressed. Buyers: What is phosphorus deoxidized copper (TP2), R410A refrigerant tube, brass oil-free? Seller: This is the difference between three basic elements of good and bad of brass. Phosphorus deoxidized copper (TP2): high purity raw materials are melted, the oxygen produced by melting copper oxophilic phosphorus (P) deoxidation to reduce the oxygen content to less 100PPm, thereby improving ductility, corrosion resistance , thermal conductivity, weldability, drawing workability, does not occur in the high temperature hydrogen embrittlement. Phosphorus deoxidized copper can be used in refrigeration and air conditioning, heat exchangers, radiators, cylinder head gasket and other purposes. The brass used as a gasoline or gas pipes, drains, condenser, torpedo tubes, condensers, evaporators, heat exchangers, train box parts. R410A refrigerant special brass: R410A refrigerant is a high-pressure refrigerant. Its easy to make a bad compression performance or thick enough brass pipe burst occurred case. R410A refrigerant is subjected to an extrusion process special brass casting, brass density is 2000 tons extruder can be absolute protection, and corrosion resistance, clean, high compressive strength, its long life, increase the air-conditioning work effect, is the choice for air conditioning connecting pipe. Oil-free brass: brass in the production process will inevitably be harmful sulfur oxides, dirt, dust, debris, oil, water, gas and other impurities appear. These impurities may cause deterioration of refrigerant residual oil, the cooling effect is reduced; also may enter the circulatory system, leading to deterioration of the oil, compressor failure, resulting in damage to the air conditioning. It is called oil-free brass, is a degreasing process which increases the program finished stage. 3, the buyer: the difference between thick and thin brass of brass? Seller: Although the thickness of the wall of the same size brass differ only 0.2mm, but it directly affects the future operation of the air conditioning cooling (heating) effect, could not see anything unusual in the short-term effect, but over time difference cooling effect of slowly emerged, and while there is a thin brass pressure leak easily breakdown, cause problems, and finally give customers a lot of unnecessary trouble.
