BOILER TUBE
Founded in 2013, Yantai Xinbaoshang Materials Technology Co., Ltd.
China's leading boiler tube manufacturer and supplier
Boiler tubes are critical tubular components specifically engineered for boilers and high-temperature pressure systems, serving essential functions in heat transfer, fluid conveyance, and pressure containment. Manufactured from high-quality carbon steel, alloy steel, or stainless steel via seamless cold-drawing or hot-rolling processes, they ensure structural stability, creep resistance, and reliability under high-temperature, high-pressure, and cyclic thermal stress conditions. Renowned for precise dimensional accuracy, consistent wall thickness, and exceptional oxidation resistance, these tubes enhance heat exchange efficiency, prevent medium leakage, and guarantee long-term operational safety. Material selection is strictly based on operating temperature, pressure parameters, and medium characteristics, with common materials including low-alloy heat-resistant steel and austenitic stainless steel. Boiler tubes are widely used in critical applications such as power station boilers, industrial steam generators, heat recovery units, superheaters, and heat exchange equipment, forming an indispensable foundation for high-temperature pressure systems in energy, chemical, and power industries.
As a leading manufacturer and supplier of boiler tube products in China, our products cover most application scenarios in terms of size and standards. Our products strictly comply with international standards such as API and ASTM. If you have any other requirements for product specifications, please feel free to contact us for customization.
