5-15m ASTM B28 C12000 Red Copper Tube 22mm Coil Copper Pipe For Radiato

Red copper pipe is a kind of non-ferrous metal pipe. It is pressed and drawn into a metal tubular material hollow along its longitudinal length. Can have one or more closed through holes, wall thickness, uniform cross section, in straight line or roll delivery.

Copper coil tube is a kind of copper tube. Divided by shape: square copper coil, round copper coil, shaped copper coil. According to the production mode, it is divided into drawn tube, rolled tube and extruded tube. Generally, middle and low pressure pipes are drawn tube. According to the standard, it is divided into: seamless copper pipe for air conditioning and refrigeration equipment GB/T 17791-2007. Seamless round copper tube for electric conductivity for cable GB/T 19850-2005. Oxygen free copper tube for magnetron GB/T 20301-2006. Seamless copper pipe with internal thread GB/T 20928-2007.

The advantages of copper pipe

Copper pipe has high low temperature strength. It is often used to manufacture heat transfer equipment (such as condenser, etc.). It is also used for assembling low-temperature pipelines in oxygen production equipment. Small diameter copper pipe is often used for conveying pressure liquid (such as lubrication system, oil pressure system, etc.) and used as instrument pressure tube, etc. Copper pipe with strong, corrosion resistant characteristics, and become modern contractors in all residential commercial housing water pipes, heating, refrigeration pipeline installation.
Pure copper - red copper tube T2 (Japanese standard red copper tube C1100) : also known as pure copper, copper purity ≥99.9%. Good thermal conductivity, processing, ductility, corrosion resistance and weather resistance. It can be used in chemical industry, hVAC, mechanical equipment, water supply system and other industries with pipes and fittings.

Pure copper - T3 red copper tube, copper purity ≥99.70. Good electrical conductivity, heat conduction, corrosion resistance and processing properties, can be welded and brazed. However, it contains more impurities that reduce electric and thermal conductivity, and oxygen content is higher than T2, which is more likely to cause "hydrogen disease" and can not be used at high temperature (such as gt; 370℃) in reducing atmosphere processing (annealing, welding, etc.) and use.

Phosphorus deoxidized copper tube TU1/ The United States copper C10200/ Japan copper C1020: also known as 1# oxygen-free copper, copper purity is greater than 99.95% oxygen content is not greater than 0.03%, the total content of impurities is not greater than 0.05%, is a kind of high conductivity, processing performance and welding performance, corrosion resistance and low temperature performance are good materials.

Phosphorus deoxidized copper - copper tube TU2 (Japanese standard copper tube C1011) : also known as oxygen-free copper, copper purity purity 99.95%, oxygen content is not greater than 0.003%, the total content of impurities is not greater than 0.05%. No hydrogen embrittlement, high conductivity, good processing and welding performance, corrosion resistance and low temperature performance. Suitable for power supply, communication and electronic products and other industries with pipes and fittings.

Oxygen-free copper - gb red copper tube TP1 (Japanese standard red copper tube C1201), GB red copper tube TP2 (Japanese standard red copper tube C1220) : also known as phosphorous deoxidized copper, copper content ≥99.9%. Good ductility, extrusion, welding, corrosion resistance, weather resistance, thermal conductivity, electrical conductivity, especially suitable for welding. Suitable for air conditioning, refrigerators, heat exchangers, refrigeration and heating industries with pipes and fittings.
