16-32mm small size rubber foam ball for condenser cleaning

Product Description :
The standard stripping rubber ball is especially suitable for various condenser copper tubes, and it is also the most commonly used rubber ball in power station/power plant. The rubber ball is made of natural rubber plus foaming and special additives.

Standard stripping rubber balls can be used in a variety of rubber ball cleaning equipment and water quality.

Rubber sponge balls effectively remove biofouling and high viscosity biofouling. Suitable for stainless steel tubes and titanium alloy tube heat exchangers.
