What is a Studded Tube?
Studded tubes are a type of metal tubes. These tubes have studs welded onto the metal tube. These studs are arranged in a specific formation throughout the length of the tube. They are often used in boilers and refineries. As they increase the surface area for higher heat transfer they are used for reheating.

应用
The nail head tube group is especially suitable for compact waste heat boilers, oil-fired, gas-fired boilers and oil heaters. Under the same heat exchange, its weight and external dimensions are greatly reduced. The anti-fouling performance of the nail head tube group is greatly improved compared with other conventional enhanced heat transfer boiler tubes. In the case of low flue gas temperature, the nail head tube can still recover waste heat economically, and has broad application prospects in heat exchange and energy saving projects.
