Which hardness should be chosen for different pipeline fouling?

Silt, sediment, algae, and soft scale: use a soft sponge ball—gentle on pipe walls and ideal for underfloor heating systems and thin-walled plastic pipes. Scale, sticky mud, and light rust on pipe walls: opt for the medium-hard, lightly abrasive model—suitable for HVAC circulating water pipes. Thick scale, oxide layers, and severe rust in aging pipelines: choose the hard, abrasive or particle-enhanced model—best for metal steel pipes and galvanized pipes. Dust and debris in dry pipes: use a high-density, closed-cell dry-cleaning ball.

Silt, sediment, algae, and soft scale: use a soft sponge ball that won’t damage the pipe walls—ideal for underfloor heating systems and thin-walled plastic pipes.
Scale, slime, and light rust on pipe walls: medium-hardness + lightly abrasive grade, suitable for HVAC circulating water pipes;
Old pipelines with thick scale, oxide layers, and rust: use the hard abrasive / grit-containing model, suitable for metal steel pipes and galvanized pipes.
Dry pipe dust and debris removal: high-density closed-cell dry-cleaning balls.

Will prolonged soaking in hot water cause it to deform or deteriorate?

Qualified, high-temperature-resistant specialized models will not soften, crack, swell, or flake off; in contrast, low-quality, standard rubber balls will soften, stick together, and break down after prolonged exposure to high temperatures, leading to secondary blockages in the piping system. Therefore, it is essential to select specialized models that are explicitly labeled with their temperature-resistance ratings.

What is a pipeline cleaning ball?

Pipeline cleaning balls, also known as sponge pigs or projectile cleaning balls, are primarily made of high-density open-cell or closed-cell polyurethane sponge, with options for varying hardness and density, and featuring either a matte or rubberized coating on the outer layer. Driven by compressed air or water pressure, they frictionally engage with, adsorb to, and dislodge contaminants within pipelines, making them a non-invasive, consumable cleaning tool specifically designed for HVAC systems, water supply and drainage networks, and industrial piping.

What types of dirt can high-temperature-resistant rubber balls remove?

Effectively removes: sludge, rust, biofouling, mild carbonate scale, suspended particulates, oxide layers on pipe walls, and adherent impurities in high-temperature water pipes; Not suitable for: extremely thick, hard crystalline scale, protruding hard scale on pipe walls, and large blockages caused by weld slag.

How should high-temperature-resistant rubber balls be stored and maintained?

Store in a cool, well-ventilated, and dry place; avoid prolonged exposure to direct sunlight, high-temperature baking, and corrosion from oil or grease. Do not subject to crushing or heavy pressure during long-term storage to prevent permanent deformation that could compromise the fit.

What are the differences between acid- and alkali-resistant rubber balls and ordinary sponge balls or ordinary rubber balls?

Ordinary sponge balls readily swell, fracture, shed debris, and undergo corrosive degradation when exposed to acids or bases; ordinary rubber balls exhibit poor corrosion resistance and are prone to hardening, cracking, and sticking in strong alkaline or acidic environments. In contrast, acid- and alkali-resistant specialized rubber balls offer superior chemical corrosion resistance, remain non-swelling and non-degrading, and maintain stable elasticity, making them ideal for long-term cleaning in corrosive operating conditions.
