Start with C12200 Copper C12200 copper contains 99.9% copper and trace amounts of phosphorus, and it is characterized by its ease of cutting, bending, and welding. Nitrogen Gas Charging Process The purpose of the nitrogen gas charging process is to remove impurities,deoxygenate,and achieve antioxidation and corrosion prevention effects. Leakage Inspection with ET ET (Eddy Current Testing) is conducted to verify the integrity of copper tubing, ensuring it is free from cracks and defects. Annealed Seamless Tubing Each copper coil is well wrapped and packed in seal bag,prevents from potential temperature variations,moisture,and physical damage. Precisely Cut and Well Packed Typical Applications of Refrigeration Copper Tubing Is "ASTM B280" an established standard? Yes.But ASTM B280 does not specify a fixed wall thickness range but offers multiple available specifications to meet various refrigeration and heating applications. What are the common copper tube sizes used in air conditioning units? Liquid line(LL) typically ranges from 1/4" to 5/8" ID, with common sizes of 1/4", 3/8", 1/2", and 5/8". Vapor line(VL) ranges from 3/8" to 7/8" ID, with common sizes of 3/8", 1/2", 5/8", 3/4", and 7/8". Is "tube size" the same as "OD" (outside diameter)? No."Tube size" pertains to inner diameter(ID), while "OD" refers to outer diameter. Both are crucial in different contexts, impacting tubing performance. When using copper tubing, consider both dimensions. What are the typical applications for refrigeration copper tubing? Refrigeration copper tubing find widespread applications in air conditioning systems, refrigeration and freezing equipment, heat pump systems, cooling systems, industrial refrigeration, and more. How to maintain refrigeration copper tubing? Regularly maintain the entire condenser system, which includes checking and replenishing refrigerants, inspecting pressures, ensuring electrical wiring and connections are in order, to ensure the system operates at its best.
