Large diameter copper pipe, can be called large caliber copper pipe, large caliber copper pipe can also be divided into: seamless copper pipe and straight seam (can also be called welding), large caliber copper pipe specifications are generally in the external diameter of 89mm or more; can be collectively referred to as large caliber copper pipe.
Large-diameter copper tube products are: large-diameter thin-walled copper tube, large-diameter thick-walled copper tube, large-diameter copper square tube, large-diameter rectangular copper tube and other products.
Large-diameter copper pipe is divided into: drawn tube and extruded tube according to the production method. According to the shape is divided into: square tube, round tube, shaped copper tube. According to the thickness: thin-walled copper tube and thick-walled copper tube. According to the use of points: seamless copper tube and copper welded tube. Large caliber copper pipe specifications general outside diameter of 89mm or more can be called large caliber copper pipe.

Group.
Pure copper - T1 copper tubes: copper purity ≥ 99.95. The grade of copper tubes have good electrical conductivity, thermal conductivity, corrosion resistance and processing performance, can be welded and brazed. Contained in the reduction of electrical conductivity, thermal conductivity impurities are less, trace amounts of oxygen on electrical conductivity, thermal conductivity and processing and other properties do not have much impact, but easy to cause "hydrogen disease", should not be in the high temperature (such as > 370 ° C) in a reducing atmosphere processing (annealing, welding, etc.) and use.
Pure copper - T2 copper: also known as pure copper, copper purity ≥ 99.9%. It has good thermal conductivity, processability, 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 copper: copper purity ≥ 99.70, has a better electrical conductivity, thermal conductivity, corrosion resistance and processing performance, can be welded and brazed. However, containing reduced conductivity, thermal conductivity impurities, oxygen content is higher than T2, more likely to cause "hydrogen disease", not at high temperatures (such as > 370 ℃) reducing atmosphere in the processing (annealing, welding, etc.) and use.
Oxygen-free copper - TU1 copper: also known as 1 # oxygen-free copper, copper purity greater than 99.97% oxygen content of not more than 0.03%, the total content of impurities is not more than 0.05%, is a kind of high electrical conductivity, processing performance and welding performance, corrosion resistance and low-temperature performance of the material are good.
Oxygen-free copper - TU2 copper tubes: also known as 2 # oxygen-free copper, copper purity purity of 99.95%, oxygen content of not more than 0.003%, the total impurity content of not more than 0.05%. No hydrogen embrittlement, high electrical conductivity, processing performance and welding performance, corrosion resistance and low temperature performance are good. Suitable for power supply, communications and electronic products and other industries with pipe and fittings.
Phosphorus deoxidized copper - TP2 copper tubes: also known as phosphorus deoxidized copper, copper content ≥ 99.9% or more. Ductility, extrusion processing, welding, corrosion resistance, weather resistance, thermal conductivity, electrical conductivity are good, especially for welding. Applicable to air conditioning, refrigerators, heat exchangers, refrigeration and heating industries with tubes and fittings.
Copper tube is a kind of non-ferrous metal tube. It is pressed and drawn seamless tube. Lighter weight, good thermal conductivity, high strength at low temperature. Commonly used in the manufacture of heat transfer equipment (such as condensers, etc.). Also used for oxygen equipment in the assembly of low-temperature piping. Large diameter copper pipe is commonly used in manufacturing equipment, building decoration projects, refrigeration piping. Copper pipe has a strong, corrosion-resistant properties, and has become a modern contractor in all residential commercial housing water piping, heating, refrigeration piping installation.
