JONENG
A typical Armstrong stainless steel thermostatic SS304 superheated steam flange steam trap follows industry material and dimensional standards, with a body made from stainless steel (e.g., ASTM A240 or A351 Grade CF8M) for corrosion resistance in high‑temperature steam service. Typical dimension standards conform to common flanged connections for industrial piping (e.g., ANSI/EN flange norms). These traps generally operate over a pressure range up to around 40–62 bar (580–900 psig) and handle steam temperatures up to approximately 315–482 °C (600–900 °F) depending on model and rating. Such specifications ensure reliable condensate removal in superheated steam applications while maintaining structural integrity.
The Armstrong stainless steel thermostatic SS304 superheated steam flange steam trap operates using a thermostatic element that reacts to temperature changes in the steam system. When condensate or cooler fluid enters the trap, the element contracts, opening the valve and allowing condensate to discharge. As live superheated steam reaches the trap, the element expands due to the higher temperature, closing the valve tightly to prevent steam loss. This cycle repeats continuously, ensuring that condensate is efficiently removed while maintaining superheated steam in the system. The design provides precise temperature-based control, energy efficiency, and reliable operation under high-pressure, high-temperature conditions.
