Heat Exchanger Cleaning Powder — Scale removal

Description

1. Product Overview

This product is a high-activity, acid-based cleaning compound formulated specifically for the chemical dissolution of calcium carbonate, iron oxide, and silicate scales in heat exchangers. It is deployed in circulating or soak-cleaning protocols for shell-and-tube, plate, and finned-tube exchangers. The key value proposition is maximum scale removal with minimal base metal corrosion (inhibited formula). Strategically, it reduces unplanned downtime and energy penalties—critical as global industries face tightening emissions and efficiency regulations.

2. Key Specifications & Technical Characteristics

• Chemical composition: Sulfamic acid (primary) + citric acid (secondary) + proprietary ternary inhibitor system (copper/steel-safe) + anti-caking agent

• Purity grade: ≥99.2% active descaler content, industrial reagent grade

• Physical characteristics: White to off-white free-flowing powder; 98% passes through 200 mesh; bulk density 0.85–0.95 g/cm³

• Packaging options: 25 kg laminated HDPE bags (palletized, shrink-wrapped), 500 kg supersacks, custom 1,000 kg bulk bags

• Shelf life: 24 months in unopened, dry storage (<60% RH, 5–40°C)

3. Core Industrial Applications

• Primary industries: Oil & gas refineries, thermal power plants (condensers & coolers), chemical processing, district heating, marine engineering, and food-grade dairy pasteurizers

• Operational use cases: Online circulating cleaning of carbon steel exchangers; offline immersion cleaning of stainless steel and titanium bundles; removal of hard scale before hydrotesting or turnarounds

• Performance advantage: Unlike liquid acids (HCl), it produces no harmful acid fumes, is non-volatile, and enables safer transport and storage. Compared to mechanical cleaning, it eliminates tube wall erosion and reaches blind passages—reducing cleaning time by 50–70% and improving post-cleaning U-values back to ≥95% of design.

4. Competitive Advantages

• Quality consistency: Batch-to-batch UOP and ASTM D808 test compliance; third-party COA with every shipment

• Supply reliability: Dual-sourced raw materials with 50 MT safety stock at regional hubs (Rotterdam, Houston, Shanghai)

• Logistics capability: 3-day dispatch for LTL; 10-day lead time for full container loads; temperature-controlled warehousing option

• Price competitiveness: 12–18% lower delivered cost vs. European and Japanese equivalents due to direct manufacturing and port-to-port consolidation

• Sustainability: Biodegradable surfactants; no heavy metals or APEOs; packaging is 100% recyclable LDPE

• Technical support: Free cleaning protocol optimization via digital twin simulation (upon NDA); onsite dosing and neutralization assistance available

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 5 metric tons (MT)

• Bulk loading capacity per 20FT container: 20 MT (net) — maximizes freight economics ✅
