It often takes time for customers to realize that using a service team without proper standards can affect production results. That’s where we step in — providing reliable, skilled engineers, skilled manpower who know how to get it right.
Right now:
Busy? Yes.
Worth it? Always!
Low-Temperature Chloride Corrosion in Boilers — Small Moisture, Big Damage
When hot gas meets a cool, slightly damp metal surface, moisture condenses and dissolves chloride salts/gases. That kick-starts a rapid corrosion cycle.
Role of Chloride Ion (Cl⁻) in Pitting (Quick Take)
Cl⁻ doesn’t oxidize iron directly; it breaks the protective Fe₂O₃ film, creating local defects → pitting
Cl⁻ penetrates crevices/under deposits, forming soluble iron chlorides → sustained metal dissolution
Key reactions:
Fe²⁺ + 2Cl⁻ → FeCl₂
FeCl₂ + 2H₂O → Fe(OH)₂ + 2HCl
→ HCl acidifies and regenerates Cl⁻, so the corrosion loop repeats
Where it hits hardest
– Pitting on tubes/headers
– Crevice corrosion at gaskets, lap joints, clips
– Under-deposit corrosion beneath sticky ash/salts (economizer, air heater, SH/REH inlets)
Why TEKE Cleaning (Dry) > Wet Cleaning

Message AGON PACIFIC to plan a TEKE Dry Cleaning for your boiler!
The Superheater is one of the most critical boiler pressure parts. Its main job: turn saturated steam into superheated steam – stronger, drier, and more efficient.
Key Functions
Radiant Superheater – absorbs heat directly from furnace radiation
Convection Superheater – heated by flue gas flow after furnace
Combined Superheater – uses both radiation + convection for optimum performance
At AGON Pacific, we ensure mechanical design and fabrication under ASME Code:
ASME Section I – thickness, stress, and allowable design
Materials – SA213 T22, T91, TP347H, creep-resistant alloys
Fabrication – precision coil bending, header welding, nozzle prep
Quality Control – RT/UT, hydrostatic test, dimensional checks
