G-Type finned tubes, also known as grooved finned tubes or embedded-fin tubes, are one of finned tube types where the "G" stands for grooved. These tubes are formed by twisting a fin strip, typically made of copper or aluminium, into a machined groove on the outer surface of the tube. The fin strip is then back-filled to securely lock it in place, ensuring a tight fit. The base tube material is completely surrounded and filled by the fins.
The specific materials, dimensions, and groove designs of G finned tubes can vary depending on the application requirements and operating conditions. Factors such as fluid characteristics, operating temperature, and pressure influence the selection of materials to ensure optimal heat transfer performance.
In summary, G-Type finned tubes are a robust and effective solution for high-temperature heat transfer applications. Their grooved design and secure locking mechanism provide strength and durability, enabling efficient heat exchange and contributing to overall system performance.
