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.

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.
YUHONG GROUP Studded Tube main technical parameters:
1. Rated input capacity: 90KVA
2. Rated input voltage: 380V±10%
3. Diameter of welded steel tubes: 60-220mm
4. Diameter of welded studs6-14mm (and other abnormally shaped
studs)
5. Effective length of welded steel tubes: 13m
6.Axial spacing of welded studs: can be freely adjusted
7. Arrangement of radially welded studs: even number
8. While welding stainless steel materials, preheater is required
(made by user self).
