1. What is Steam Condensate Pipe Sizing?

Steam condensate pipe sizing involves determining the appropriate pipe diameter to handle condensate flow while maintaining proper velocity. Proper sizing ensures efficient condensate removal and prevents water hammer or drainage issues in steam systems.

2. How Does the Calculator Work?

The calculator uses the fundamental velocity formula:

Where:

• \( Velocity \) — Fluid velocity in feet per minute (fpm)
• \( Flow \) — Condensate flow rate in pounds per hour (lb/hr)
• \( Area \) — Pipe cross-sectional area in square inches (in²)

Explanation: For steam condensate systems, recommended velocity ranges from 4000 to 8000 fpm to ensure proper drainage while minimizing pressure drop and erosion.

3. Importance of Proper Pipe Sizing

Details: Correct condensate pipe sizing is crucial for system efficiency, preventing water hammer, ensuring proper steam trap operation, and maintaining system pressure integrity. Undersized pipes can cause flooding while oversized pipes may lead to inadequate drainage.

4. Using the Calculator

Tips: Enter condensate flow rate in lb/hr and desired velocity between 4000-8000 fpm. The calculator will determine the required pipe area and corresponding diameter.

5. Frequently Asked Questions (FAQ)

Q1: Why is velocity important in condensate piping?
A: Proper velocity ensures condensate is carried away efficiently without water accumulation, prevents steam locking, and minimizes the risk of water hammer.

Q2: What happens if velocity is too high?
A: Excessive velocity can cause erosion, increased pressure drop, and potential damage to piping components and steam traps.

Q3: What happens if velocity is too low?
A: Low velocity may lead to inadequate drainage, condensate pooling, water hammer, and reduced system efficiency.

Q4: Are there other factors to consider in pipe sizing?
A: Yes, consider pipe material, system pressure, temperature, elevation changes, and the presence of flash steam in the condensate line.

Q5: Can this calculator be used for other fluids?
A: This calculator is specifically designed for steam condensate. Other fluids may require different velocity ranges and calculation methods.
