Large copper tubes with an outer diameter of 28-54mm

Large copper tube with an outer diameter of 28-54mm possess excellent pressure resistance and a stable structure, specifically designed for high-load, high-pressure piping systems. They are widely used in critical areas such as building water supply and drainage, large industrial heat exchangers, and power plant conduits. As a high-performance piping material, they possess natural corrosion resistance, enabling long-term stable operation in humid, corrosive gas or liquid environments. Their strong pressure resistance makes them particularly suitable for piping systems in high-pressure and high-flow environments, ensuring the safe and stable operation of the system.

In building water supply and drainage systems, large copper tubes are often used as main pipelines. Their excellent corrosion resistance ensures that water quality is not contaminated and effectively resists corrosion from the external environment, extending the service life of the pipeline. In industrial applications, especially in large industrial heat exchangers, copper tubes, due to their superior thermal conductivity and corrosion resistance, are often used as transmission pipelines for heat exchange media, helping to improve heat exchange efficiency and reduce energy loss. Furthermore, in the power industry, particularly in power plant conduit systems, these copper tubes can withstand high-pressure transmission and high-temperature environments, ensuring the stable operation of cooling and steam systems and effectively preventing equipment downtime due to pipeline failures.

The wall thickness of this copper tube can be customized to meet specific needs, ensuring its safety and stability under high-pressure environments. Whether for large-scale industrial projects or customized requirements in the construction sector, this copper tube provides an efficient and stable solution.

Industry knowledge

Copper tubes are the "blood vessels" of the refrigeration system, mainly used in condensers, evaporators and connecting pipelines. Its high thermal conductivity (with a thermal conductivity coefficient of approximately 400 W/m·K) enables rapid heat transfer, enhancing the energy efficiency ratio of air conditioners and refrigerators. The promotion of environmentally friendly refrigerants such as R410A has further driven the development of copper tubes towards high pressure resistance, thin-walled and lightweight. Industry standards such as ASTM B280 (Copper Tubes for Air Conditioning) have strict regulations on indicators such as cleanliness and tensile strength to avoid refrigerant leakage and system blockage.
