Threaded Flange Heater Factory

-- Steady & Reliable Manufacturer --

Introduction

Sinton Electric is a precision threaded flange heater factory, manufacturing robust and easy-to-install immersion heaters for a wide range of industrial tanks and pressurized vessels. Our threaded flange heaters combine the powerful, direct heating of an immersion heater with the convenience of a threaded connection, eliminating the need for a separate flange and gasket. Engineered for durability and performance, they are the ideal solution for heating water, oil, chemicals, and other process fluids.

SINCE 2001

Sinton Electric Co.,Ltd.

Applications

  • Chemical Process Vessels

  • Freeze Protection for Vessels

Our Advantages

  • Easy Installation: The threaded design allows for simple screw-in installation, saving time and labor costs compared to bolted flange heaters that require gaskets and multiple bolts.

  • Leak-Free Design: The heater and flange are a single, welded unit, and the threaded connection provides a secure, leak-free seal when installed correctly with sealant.

  • Customization: We can customize the wattage, voltage, element material, and length of the heating elements to perfectly match your tank and process requirements.

Payment & Shipping

We accept T/T and L/C. We ship globally via sea and air freight. The threaded connections are protected during shipping to prevent damage.

Frequently Asked Questions

  • Q: What is the difference between a threaded flange heater and a standard flange heater?

  • A: A threaded flange heater screws directly into a threaded tank opening. A standard flange heater bolts onto a matching flange on the tank, requiring a gasket. Threaded is simpler; bolted is more common for larger sizes and higher pressures.

  • Q: How do I choose the right thread size?

  • A: The thread size must match the existing opening in your tank. Common sizes are 1.5", 2", and 2.5" NPT. You must also ensure the heater's power is appropriate for the volume of fluid you are heating.

  • Q: Can I use a threaded flange heater on a pressurized vessel?

  • A: Yes, but you must ensure the heater's pressure rating and the pressure rating of the tank connection are compatible with your operating pressure.

  • Q: What is the best way to prevent corrosion?

  • A: Choose the correct sheath material. Use copper for clean water, steel for oil, and stainless steel or Incoloy for corrosive water or chemicals.

  • Q: Can a thermostat be added to a threaded flange heater?

  • A: Yes, we can equip our threaded flange heaters with a built-in, adjustable thermostat for basic temperature control. For more precise control, we recommend using an external controller with a thermocouple.

  • Q: What is a thermowell and should I get one?

  • A: A thermowell is a protective pocket that holds a temperature sensor. We highly recommend adding one so you can accurately measure the fluid temperature and remove the sensor for replacement without draining the tank.

  • Q: Do you offer different thread types like BSP?

  • A: Yes, we can manufacture heaters with NPT (American), BSP (British), or other standard thread types to meet your requirements.

  • Q: How do I size a heater for my tank?

  • A: You need to calculate the required kW based on the volume of fluid, the desired temperature rise, and the heat loss from the tank. Our engineers can assist you with this calculation.
