ASTM A335 P11 Alloy Steel Studded tube For Heat Exchanger
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.

Application
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.
