Why TEKE Cleaning is the Smarter Choice?

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 🌬️ > 💦
✅ Removes hygroscopic chloride deposits without adding water → less re-wetting/flash rust
✅ No wastewater/sludge; no chloride-rich liquid seeping into crevices
✅ Shorter downtime → faster return to service
✅ Better long-term protection: clean, dry metal = fewer moisture/Cl⁻ cells

Superheater – Engineered for Performance & Reliability

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
✅ Increase Steam Temperature – raises steam above saturation point for higher plant efficiency
✅ Ensure Dry Steam – protects turbines and piping from erosion & water hammer
✅ Improve Efficiency – reduces fuel use per kWh by boosting Rankine cycle performance
✅ Protect Equipment – prevents moisture-related corrosion and extends service life
⚙️ Types of Superheater
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
🏭 AGON Pacific Capability
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
✅ With certified engineers and skilled fabrication teams, AGON Pacific delivers Superheaters built for safety, quality, and long service life – ready for power plants, biomass, and industrial boilers.

Hot Bend vs Cold Bend – Key Differences

Cold Bend – Bend at ambient temperature using mechanical force
✅ Faster, no heat distortion
⚠ Risk: Wall thinning & ovality if radius is tight
Hot Bend – Heat tube (induction/furnace) before bending
✅ Lower stress, more uniform thickness, ideal for tight radius & hard materials
⚠ Requires temperature control, PWHT, oxidation protection
📐 Rule of Thumb
• Cold Bend: R/D ≥ 1.3
• Hot Bend: R/D < 1.3, thick wall, low ductility, alloy steels
⸻
📏 Extrados Thickness Check (UTM)
1️⃣ Reference Thickness
• Measure straight tube wall (before bending) → baseline tthckness of straight tube.
2️⃣ Measurement Points
• Readings at Apex (180°), ±30°, ±60°, ±90°
• Record extrados (12 o’clock) thickness
• Optional: check intrados (6 o’clock) & neutral sides (3 & 9 o’clock)
3️⃣ Acceptance Criteria
• Wall ≥ design minimum thickness
• Ovality ≤ 10%
⸻
🔎 At Agon Pacific, every bend is controlled by ASME & OEM tolerances for ovality, wall thinning, and hardness. With UTM verification, we ensure bending precision and reliable service life.
✅ Precision bending = Longer service life

Boiler Pressure Parts Fabrication – AGON PACIFIC

📌 Image 1–2: Tube Bending for Superheater Coils
Material: ASTM A213 TP347H
These austenitic stainless steel tubes are precisely bent and subjected to post-bending heat treatment to relieve residual stresses and restore material properties. The discoloration seen is typical of heat-treated surfaces, indicating controlled thermal exposure to meet high-temperature service requirements.
📌 Image 3–4: Water Wall Panel Assembly – Spare Parts for Boiler
Fin-welded membrane panels fabricated to tight tolerances to ensure pressure part integrity and optimized heat absorption in the furnace zone. All welding joints are prepared for further NDT prior to final painting and dispatch.
At AGON PACIFIC, we ensure all fabrication processes strictly follow ASME Section I and customer specifications, including WPS/PQR, material traceability, and dimensional QC.
