Large-diameter copper pipes have strong corrosion resistance, can withstand strong acids, strong alkalis and other chemical corrosion, are non-toxic, non-corrosive, wear-resistant, impact-resistant, and have strong penetration resistance. The surface of the pipe is smooth and does not adhere to any substance, which can reduce the transportation When the resistance, improve flow and delivery efficiency, reduce delivery pressure loss. Light weight, good thermal conductivity, high strength at low temperature. It is often used in the manufacture of heat exchange equipment (such as condensers, etc.). It is also used to assemble cryogenic pipelines in oxygen generating equipment. Copper tubing with a large diameter is often used in manufacturing equipment.
Shanghai Changjin produces and manages large-diameter brass tubes. It is one of the large-diameter brass tube production bases in China. It uses imported equipment, vacuum melting technology and advanced processing technology for production to ensure that the copper tubes have no blisters, no leakage, smooth surface, Good eccentricity, product quality has reached the international level, annual production capacity of 10,000 tons, exported to the United States, Japan, Europe, Southeast Asia and other countries and regions.
Our large diameter brass tubing is available in convenient stock sizes, but can be precisely cut to your exact requirements. We can also provide customized services according to customer needs.







We also provide forging blanks and CNC precision machining services for our clients, covering industries such as energy, petrochemicals, steel, engineering machinery, plastics, prevention and control, hydraulics, healthcare, and food. Please feel free to send us drawings for inquiries.
