Casting Mild Steel TD3 Thermodynamic Steam Trap, Brand Name : N-TORK

Description:

The TD (Thermodynamic) steam trap operates on the principle of pressure and temperature difference between steam and condensate. It has a simple design—usually a flat disc on a seat inside a chamber.

🧩 Main Components:

1. Body: Typically made of stainless steel or carbon steel, designed to withstand high pressure and temperature.

2. Disc: Moves up and down based on pressure differences.

3. Seat: The sealing surface for the disc.

4. Cover: Houses the disc and provides access for maintenance.

🔧 Working Principle:

1. Condensate Entry: When condensate enters, it lifts the disc, allowing discharge through the outlet.

2. Steam Arrival: When steam reaches the trap, the pressure above the disc increases rapidly.

3. Disc Closes: The high-pressure steam above the disc holds it closed until the steam cools and condenses.

4. Cycle Repeats: Once the steam condenses, pressure drops, the disc lifts again, and the process repeats automatically.

📐 Key Features:

• Compact, simple, and robust construction

• Suitable for high pressure and high temperature applications

• Operates in any position (horizontal or vertical)

• No moving parts other than the disc — low maintenance

• Resistant to water hammer and vibration
