S160、L160 Sponge-Type Cleaning Ball

Description

The S160、L160 Sponge-Type Cleaning Ball is a standard cleaning ball designed for online tube cleaning systems. It is particularly suitable for copper-nickel and brass condenser tubes operating with low-salinity cooling water. When used together with a controlled dosage of ferrous sulfate (FeSO₄), it effectively removes soft bio-fouling deposits while protecting the tube surface.

Physical Properties

• Density: 1.03–1.06 g/cm³
• Hardness: Shore C 23–28
• Aging Coefficient: ≥ 0.70
• Maximum Water Temperature: 80°C

Key Features

• Ultra-soft sponge structure
• High porosity and excellent comprehensibility
• 100% tube pass-through rate
• Minimizes the risk of ball jamming
• Ideal for delicate and thin-wall tubing

The S160、L160model can also be used as a long-life cleaning ball (L160) due to the relatively rough inner surface of copper-alloy tubes, providing extended service life and improved wear resistance

Applications

Recommended for:

• New copper and copper-alloy tubes
• Brass tubes
• Thin-wall titanium tubes
• Small-diameter condenser tubes
• Systems requiring removal of biological soft fouling only

Cleaning Frequency

• Low-salinity water: 12 cleaning balls per tube per hour
• Seawater applications: Cleaning frequency should be determined based on site conditions and operating tests

Typical Fouling Removed

• Biofilm
• Slime deposits
• Soft organic fouling
• Early-stage biological growth

The S160、L160 cleaning ball is specifically designed for continuous online cleaning of heat ex-changer and condenser tubes, ensuring optimal heat transfer efficiency while minimizing tube wear and maintenance costs.
