Higher heat transfer efficiency due to increased turbulence. Better mechanical strength (studs resist erosion & vibration). Easier cleaning compared to tightly wound spiral fins. Customizable stud pitch & height for optimized performance.
TP304: Lower cost, good general corrosion resistance. TP316: Contains 2-3% Molybdenum for better chloride & pitting resistance (e.g., seawater, acidic environments). Choice depends on environment--TP316 is preferred for harsher conditions.
Yes, A312 TP304 tubes are rated for high-pressure use, but the operating limits depend on wall thickness, temperature, and stud welding integrity.
Not ideal for prolonged high temps (>500°C/932°F) due to carbide precipitation (sensitization). Weaker chloride resistance than TP316--may suffer pitting in saltwater or acidic chloride environments. Higher cost than carbon steel, but longer lifespan in corrosive settings.
Studs are resistance-welded or arc-welded onto the base tube in a staggered/helical pattern. Materials: Base tube (A312 TP304) + studs (usually same or higher-grade SS). Testing: Hydrostatic, ultrasonic (UT), or eddy current (ET) testing for quality assurance.
Consider fluid type (corrosive, abrasive, high-temp), pressure & temperature requirements, stud pitch/density (affects heat transfer & pressure drop), and material upgrade options (TP316L, 321, or duplex SS for harsher conditions).
Specialized manufacturers of heat exchanger tubing (e.g., FinTube, Salem Tube, Wieland Thermal Solutions). Custom orders are available for specific stud patterns, lengths, and testing requirements.
