Steam Engineering Guides
Practical engineering guides for steam system designers, plant engineers, and HVAC professionals. Each article links to the relevant free online tool.
Pressure Locking in Float & Thermostatic Steam Traps
Why a mechanically sound F&T trap stops passing condensate — and how to specify around it. Covers the physics of pressure locking, how to distinguish it from air binding and collapsed ball float, and concrete selection guidance.
Sizing Steam Mains for Warmup Loads: Why Your Running Load Calculation Isn't Enough
Steam mains must be sized for startup warmup loads, not just steady-state running loads. This guide covers how to calculate warmup condensate rates, why they dwarf running loads, and how to size traps and drip legs correctly.
Heat Exchanger Stall: What It Is, Why It Happens, and How to Prevent It
A complete guide to steam heat exchanger stall — the conditions that cause it, how to calculate the stall point, and when a condensate pump is required to prevent flooding and water hammer.
How to Size a Steam Trap: A Practical Guide
Learn how to select the right steam trap for heat exchangers, heating coils, and tracer lines. Covers condensate load calculation, safety factors, trap types, and common sizing mistakes.
