A bare tube radiator is a highly efficient and energy-saving heating device widely used in industrial, agricultural, commercial, and residential heating systems. It uses steam, hot water, or thermal oil as the heat transfer medium and releases heat into the surrounding environment through a pipe arrangement structure, providing stable and effective heating performance.
Due to its simple structure, strong heat output, long service life, and easy installation, bare tube radiators have become an important heating solution for factories, workshops, greenhouses, warehouses, and large commercial spaces.
A bare tube radiator is a type of pipe heating radiator manufactured mainly from steel tubes. The radiator transfers heat through the surface of the tubes, allowing heat energy from the internal medium to be released efficiently into the air.
Depending on the heat transfer medium, bare tube radiators are generally classified into:
Steam-type models provide higher heat transfer temperatures and are commonly used in large-area heating applications such as industrial workshops, factories, and greenhouse facilities.
Bare tube radiators are usually manufactured using:
The steel pipe structure provides excellent mechanical strength, corrosion resistance, and long-term durability. Some models undergo surface treatment processes to improve corrosion protection and extend service life.
The open pipe design maximizes the heat radiation and convection area. Heat from steam, hot water, or thermal oil is quickly transferred through the tube surface, providing efficient heating for large spaces.
The radiator design can be optimized through engineering calculations and thermal simulation analysis to improve:
