Internal grooved copper tube/Internal thread copper tube refers to the internal grooved copper with smooth outer surface and a certain number of regular threads on the internal surface.
The internal thread copper pipe is also called non smooth copper pipe, and its English name is inner grooved copper tube (IGT), which refers to the internal thread TP2 Copper Pipe with smooth outer surface, a certain number of regular threads on the inner surface.
Due to the increase of the internal surface area of the internally threaded copper tube, its thermal conductivity is 20 to 30% higher than that of the bare tube. With the world energy shortage and the implementation of the domestic energy efficiency ratio air conditioning access system, internally threaded copper pipes will be widely used in the air conditioning and refrigeration industry.

Inner Grooved Copper Tube Performance Advantages
High dimensional accuracy
Inner grooved copper tube is manufactured with high precision, ensuring its dimensions is accurate and consistent. This makes them ideal for use in applications where precise measurements are critical.
High heat dissipation performance
The inner grooves of copper tubes increase the surface area, allowing for better heat transfer. This makes inner grooved copper tubes ideal for use in heat exchangers, where efficient heat transfer is essential.
High cleanliness
Inner grooved copper tubes are manufactured using high-quality materials and advanced production techniques, ensuring they are free from impurities and contaminants. This makes them ideal for use in applications where cleanliness is essential, such as in the food and beverage industry.
Lightweight
Inner grooved copper tubes are lightweight compared to other materials, making them easy to transport and install. This makes them ideal for use in applications where weight is a concern, such as in aircraft and automotive industries.
