ASTM A106 / ASME SA106 GR.B Carbon Steel Studded Fin Tube for Refineries
Overview:
SA106 GR.B refers to a specific grade of carbon steel material that conforms to the ASTM A106 standard. It is commonly used in high-temperature and pressure applications such as in the oil and gas industry, power generation, and more.
Studded fin tubes are components used in heat exchangers and boilers to enhance heat transfer efficiency. These tubes have small studs or fins attached to the outer surface, increasing the surface area for heat transfer. This design improves the overall thermal performance of the heat exchanger or boiler by facilitating better heat exchange between the fluid inside the tube and the external environment.
When SA106 GR.B material is used to fabricate studded fin tubes, it ensures high strength, corrosion resistance, and reliable performance in demanding conditions. These tubes are designed to withstand high temperatures and pressures while maintaining their structural integrity over extended periods.
Yuhong Group provides a variety of high-quality studded fin tube. Our products are exported to overseas and have won unanimous praise from customers.

Studded Fin Tube application and Work Principle:
1. The equipment is used exclusively for the welding of studded tubes. The studded tubes produced using this equipment is an energy-efficient heat exchange component. It is characterized by high heat transfer efficiency and high bearing pressure, and best adapted to high temperature areas. It is mainly used in waste heat recovery, petrochemical, heat exchange systems of power station boilers and other industries.
The application of studded tubes in heating furnace convection chamber of petrochemical industry can increase smoke side heat transfer coefficient. The area of studded tubes is 2 to 3 times that of light tubes. Under the condition of reasonable design, using studded tubes can obtain the same heat intensity as radiation.
2. Studded tube is an integrated heat exchange part processed using power frequency contact type resistance welding and upsetting force fusion welding.
3. The equipment adopts dual-torch metal tumor-free welding. Stepper motor is used for stud head division; and linear guide uses machine head slide. Welding precision is ensured.
4. The studded tubes welder is a mechanical-electrical integrated welder. The electric control part adopts PLC program control and man-machine interface parameter setting, and the operation is simple and reliable. The welding parameters adopt single board computer settings. Its performance is stable and convenient.
