Applications

Chemical & Petrochemical Plants: Heat exchangers, condensers, and reactors handling corrosive chemicals with resistance to chloride-induced stress corrosion cracking.
Oil & Gas Industry: Heat recovery systems, boilers, and furnaces in refineries and offshore platforms that withstand high temperatures and sour gas environments.
Power Generation: Boilers, superheaters, and waste heat recovery units in thermal/nuclear power plants for efficient steam and high-pressure water handling.
Marine & Desalination: Seawater desalination evaporators and shipboard heat exchangers with excellent pitting resistance.
Food & Pharmaceutical Processing: Hygienic heat exchangers with non-reactive, easy-to-clean surfaces.
Pulp & Paper Industry: Resistance to corrosive byproducts in digesters and black liquor recovery boilers.

Key Features

Material: A312 TP304 (18% Cr, 8% Ni) offers excellent oxidation resistance up to 870°C (1600°F).
Studded Fins: Enhanced heat transfer efficiency through increased surface area and improved turbulence.
Corrosion Resistance: Superior performance in acidic, alkaline, and chloride-rich environments compared to carbon steel.
Weldability & Fabrication: Easily welded and formed into custom configurations for specialized applications.

Frequently Asked Questions

What are the advantages of studded fins over plain or spiral fins?

Studded fins provide higher heat transfer efficiency through increased turbulence, better mechanical strength against erosion and vibration, easier cleaning compared to tightly wound spiral fins, and customizable stud pitch and height for optimized performance.

How does TP304 compare to TP316 for studded fin tubes?

TP304 offers lower cost with good general corrosion resistance, while TP316 contains 2-3% Molybdenum for better chloride and pitting resistance in harsh environments like seawater or acidic conditions. Material selection depends on specific environmental requirements.

Can TP304 studded tubes handle high-pressure applications?

Yes, A312 TP304 tubes are rated for high-pressure use, with operating limits determined by wall thickness, temperature, and stud welding integrity.

What are the limitations of TP304 studded fin tubes?

TP304 is not ideal for prolonged high temperatures above 500°C/932°F due to carbide precipitation, has weaker chloride resistance than TP316, and carries a higher cost than carbon steel though with longer lifespan in corrosive environments.

How are studded fin tubes manufactured?

Studs are resistance-welded or arc-welded onto the base tube in a staggered/helical pattern using base tube (A312 TP304) and studs (usually same or higher-grade stainless steel). Manufacturing includes hydrostatic, ultrasonic (UT), or eddy current (ET) testing for quality assurance.

How do I select the right studded fin tube for my application?

Consider fluid type (corrosive, abrasive, high-temp), pressure and temperature requirements, stud pitch/density for heat transfer optimization, and material upgrade options (TP316L, 321, or duplex SS) for harsher conditions.
