Studded Tube
The defining characteristic of the studded tube is the presence of numerous short cylindrical studs welded across the tube surface. This stud configuration enhances convective heat transfer while preserving structural robustness.
What is a Stud Tube?
A stud tube is a type of enhanced heat transfer tube widely used in the convection sections of industrial furnaces in industries such as petrochemical and refining. It consists of a plain base tube onto which a series of cylindrical studs are welded. These studs are typically arranged in a staggered pattern, such as square or hexagonal configurations, around the circumference of the tube. This structure increases the external surface area to two to three times that of a plain tube, significantly improving the heat transfer efficiency on the flue gas side, thereby meeting the heat transfer requirements between different fluids inside and outside the tube.
How is it Manufactured?
The primary manufacturing process for stud tubes is resistance welding. The process is precisely controlled by a PLC program. Electrodes press the stud against the surface of the steel tube, and a high electrical current generates resistance heat at the contact point. This heat locally melts the materials, and under applied pressure, the stud is firmly welded to the tube. Automatic stud feeding, precise indexing of welding positions, and parameter control are all managed by the automated system to ensure consistent weld quality for each stud.
Industrial Applications
The studded tube is widely used in:
Power plant boilers
Waste heat recovery units
Petrochemical furnaces
Refinery heaters
Incineration systems
The durability of the stud tube makes the design especially suitable for high-temperature, high-dust, and corrosive gas environments. When mechanical strength and fouling resistance are required, the studded fin tube provides a robust alternative to standard low finned tubes.
