Inner Grooved Copper Tubes

An internal thread refers to a copper tube with a smooth outer surface and an inner surface featuring a specific number of regularly arranged threads.

Copper Pancake Coils

Copper Pancake Coils are high-cleanliness, ultra-smooth, uniformly dense, and dimensionally precise copper products. They are lightweight, easy to carry, and install.

Capillary Copper Tubes

Capillary Copper Tubes very fine copper tubes with small inner and outer diameters, typically made from high-quality copper such as TP2 and TU1. Applications include: a: Refrigeration systems: Capillary copper tubes are widely used in small Freon refrigeration units below 10KW. Length and diameter can be adjusted to meet different operating conditions and cooling capacity requirements. b: Gas transmission: Suitable for cold water and environmental engineering. c: Daily life: Widely used in building water supply systems due to their excellent thermal conductivity and low-temperature strength.

Copper Straight Tubes

Copper, with a copper content of over 99%, has excellent ductility and is easy to process into various shapes. Copper tubes are widely used in refrigeration, plumbing, and electromechanical industries. Copper refrigeration tubes have excellent thermal conductivity, are easy to process, simple to weld, and have a long service life. Copper plumbing tubes have excellent bactericidal properties for drinking water, a service life of up to 100 years, and are nearly 100% recyclable. Pure copper has excellent electrical conductivity and is widely used in power, electric furnaces, and nuclear power industries.

Plastic-Coated Copper Tubes

Plastic-coated copper tubes are composite pipes made of seamless copper tubes coated with wear-resistant and corrosion-resistant polyethylene plastic. These pipes are widely used in various pipeline projects, including indoor cold and hot water pipes, buried and wall-embedded pipes, and pipes used in corrosive environments. They are also suitable for transporting gas or other gases.
