A: It depends on the acidity and temperature. SS304 is suitable for general water heating; SS316L is preferred for mildly corrosive liquids or food applications; Incoloy 800 is best for high-temperature oil and aggressive chemical baths.

A: In water, we can often reach 60-100 W/in², but in heavy oil, we must stay below 20-30 W/in² to prevent coking (carbonization) on the sheath surface. Wattheat provides specific calculations for each medium.

A: Yes. Our heaters are equipped with NPT or BSP threaded plugs and high-pressure welding to ensure they remain leak-proof at rated system pressures.

A: We use hermetic seals (Epoxy or Silicone) at the lead exit point. For high-moisture or wash-down areas, we recommend PTFE leads and specialized moisture-proof potting.

A: Common options include threaded connections, flanges, screw plugs, and custom mounting solutions for specific vessels.

A: Absolutely. We can embed Type K or J thermocouples or RTDs (PT100) inside the heater core for the most accurate measurement of the internal temperature or the surrounding fluid.
