S170, L170 Sponge Rubber Cleaning Ball for Special Water Conditions

Description

The S170,L170 Sponge Rubber Cleaning Ball is specially designed for copper and brass tubes operating in low-salinity water and other special water conditions. It is particularly suitable for online tube cleaning systems where effective removal of soft biological fouling is required while minimizing wear on tube surfaces.

Physical Properties

• Density: 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 flexibility
• 100% tube pass-through rate
• Minimizes the risk of ball blockage
• Specially developed for copper-alloy tube systems and special water quality applications
• Suitable for cleaning soft biological deposits without damaging tube surfaces
• Due to the relatively rough inner surface of copper-alloy tubes, the S170,L170 cleaning ball can also be used as a long-life cleaning ball (L170), providing improved wear resistance and extended service life

Recommended Applications

• Copper tubes
• Brass tubes
• Copper-alloy condenser tubes
• New copper tubes
• Thin-wall titanium tubes
• Small-diameter tube bundles
• Cooling water systems with low salinity or special water quality characteristics
• Applications 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 water quality analysis and operational testing

Typical Fouling Removed

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

Application Notes

For low-salinity cooling water systems, the S170,L170 cleaning ball is recommended for use with a controlled dosage of ferrous sulfate (FeSO₄) to maintain clean tube surfaces and optimal heat transfer efficiency. It is particularly suitable for copper and brass tube condensers operating under special water quality conditions.
