Sponge balls

Showa's sponge ball technology

Our company carries out in-house production of sponge balls.
Our company's sponge balls remove any slime, sludge, scale or other contaminants which are formed on the inside surfaces of narrow pipes while the plant continues operating, which improves the heat transfer performance of the pipes while also preventing corrosion that can be caused by these same materials. A variety of characteristics are tested in our company's research labs, and strict quality management is carried out on abrasion resistance, sphericity, tear resistance, stability, water absorbing qualities, sedimentation qualities and other properties to ensure uniformity of the sponge balls in order to provide a selection of sponge balls which are optimum for the narrow pipe materials, dimensions and inner surface types.

Standard ball (NB)

Washing ball for aluminum brass pipes, titanium pipes, etc.
External shape Ivory colored ball
Material Natural rubber foam
Ball shape 1mm pitches in a range of 13mm-41mm for finished external diameter and nominal diameter
Manufacturing tolerances +0mm to -1mm for nominal diameter dimensions
Qualities Uniform interconnected cells which can absorb water to the interior

Functionality and characteristics

Uses natural rubber which has superior abrasion resistance as a raw material and has a slightly higher specific gravity (when submerged) than water so it is pushed along by the water flow. We have a standing supply of general use size standard sponge balls, so time is required for shipping inspections and shipping, but there is a prompt delivery system in place.

Resin coated ball (PC)

Ball for removing comparatively hard scale which cannot be removed with the standard ball
External shape A brick colored ball consisting of hard plastic (polycarbonate and ABS) particles adhered to the surface of the standard ball
Material Body – natural rubber foam
Abrasives – polycarbonate and ABS
(Particles are 1.4mm or smaller)
Ball shape 1mm pitches in a range of 15mm-42mm for finished external diameter and nominal diameter with abrasives applied
Body – PC nominal diameter -2mm
Manufacturing tolerances +0mm to -1mm for nominal diameter dimensions
Qualities Uniform interconnected cells which can absorb water to the interior

Functionality and characteristics

Abrasive power is increased by adhering hard plastic particles to the surface of the standard ball as abrasives which allows the ball to remove comparatively hard scale that the standard ball cannot remove.

Full surface carborundum ball (CC)

Ball for removing hard scale and corrosive materials that cannot be removed even with the resin coated ball
External shape A black colored ball consisting of carborundum (silicon carbide) particles adhered to the surface of the standard ball
Material Body – natural rubber foam
Abrasives – carborundum (silicon carbide)
(Particles are 0.5mm or smaller)
Ball shape 1mm pitches in a range of 15mm-42mm for finished external diameter and nominal diameter with abrasives applied
Manufacturing tolerances +0mm to -1mm for nominal diameter dimensions
Qualities Uniform interconnected cells which can absorb water to the interior

Functionality and characteristics

Abrasive power is increased by adhering carborundum (silicon carbide) particles to the surface of the standard ball as abrasives which allows the ball to remove hard scale and corrosive materials that even the resin coated ball cannot remove.

Cone ball (CB)

Washing ball for aluminum brass pipes, titanium pipes, etc.
External shape Ivory colored ball with embedded particles
Material Natural rubber foam
Hard botanical particles
Ball shape 1mm pitches in a range of 23mm-38mm for finished external diameter and nominal diameter
Manufacturing tolerances +0mm to -1mm for nominal diameter dimensions
Qualities Uniform interconnected cells which can absorb water to the interior

Functionality and characteristics

Has higher cleaning capacity that the standard ball because hard biodegradable botanical material particles are mixed into the main body of the sponge ball to improve abrasive power. The hard biodegradable botanical material particles are broken down by microorganisms in seawater, promoting the breakdown of outflowing balls.
