Model No.: ASD-10
Brand: ASD
Uncontrolled flash steam escape and unstable pressure separation often cause energy loss and piping corrosion for industrial boiler rooms, raising site safety risks and wasting recoverable heat. Our Stainless Steel Continuous Blowdown Vessel achieves reliable two-phase separation for boiler blowdown streams. This Blowdown Expansion Vessel in Stainless Steel stabilizes internal pressure, while the Stainless Steel Container Expansion Vessel resists hot water and condensate corrosion. It belongs to our Pressure Vessels portfolio, paired with durable Stainless Steel Containers and certified High-Quality Pressure Vessels for thermal power and process heating stations.

| Application Scenario | Buyer Type | Local Pain Point | Our Advantage (Quantitative) |
|---|---|---|---|
| Industrial steam boiler continuous blowdown heat recovery system | Boiler system integrator for food and beverage plants | Local environmental and energy codes restrict raw hot blowdown discharge; carbon steel vessels corrode rapidly, requiring replacement every 24 months | Blowdown Expansion Vessel in Stainless Steel extends service life by 130%; efficient steam separation recovers up to 14% of waste heat, lowering plant fuel consumption |
Thermal system designers frequently match this Stainless Steel Continuous Blowdown Vessel with other Stainless Steel Containers and Pressure Vessels from our range to build unified heat recovery packages using High-Quality Pressure Vessels.
A food processing plant system integrator based in Auckland, New Zealand supplies steam boiler packages for dairy and beverage production facilities. Previously, their blowdown treatment setups used carbon steel expansion vessels. Hot oxygenated blowdown water triggered fast internal rusting. Before upgrading, roughly 24% of installed vessels needed full replacement within two years. Corrosion debris blocked drain lines, causing 11 unplanned boiler shutdowns annually. Maintenance crews spent an average of 12 working hours per vessel on internal inspection, descaling and corrosion repair. Local discharge regulations also demanded lower thermal discharge temperature, which older vessels struggled to achieve consistently.
They adopted our Stainless Steel Container Expansion Vessel for all new boiler blowdown skids. Across 16 months of field deployment, vessel corrosion-related failures dropped to zero. Effective steam-water separation stabilized drain temperature output and helped the sites meet local discharge standards reliably. Heat recovery from separated flash steam cut natural gas consumption for feedwater preheating by 12%. Planned maintenance hours for blowdown vessels fell by 86%, and blockage-related boiler outages were eliminated. This Stainless Steel Continuous Blowdown Vessel integrated neatly into their standard skid layout alongside other Pressure Vessels and Stainless Steel Containers, simplifying compliance documentation for each delivered boiler system.
Custom sizing and port layout are available to fit individual boiler capacity.
Optimized for continuous blowdown; it can handle intermittent blowdown with modified internals.
Material certificates and hydrostatic test documentation are supplied for each unit.
