STANDARD RED SERIES: 5-8 lb/cu.ft. (80-128 kg/cu.m)
Medium density foam with a tough red coating yields a strong resistance to wear, yet remains flexible. The 5A, IA and IC may be used in pipelines with minor cross sectional diameter reductions or restrictions. (Please consult Corrosion Control Products Company before applying a 1B, 1D or 4A where line reductions are present.

1A Red Plain Spiral (RPS)
1B Red Spiral Silicone Carbide (RSSC)
1C Red Criss Cross (RCC)
1D Red Criss Cross Silicone Carbide (RCC-SC)
4A Javelina (Wire Brush) (RCC-WB)
DURABLE CRIMSON SERIES: 9-10 lb/cu.ft. (144-160 kg/cu.m.)
Hard density durable foam and toughest crimson coating give maximum wear resistance.
2A Crimson Bare Squeegee (CBS)
2B Crimson Criss Cross (CCC)
2C Crimson Criss Cross Wire Brush (CCC-WB)
2D Crimson Criss Cross Silicone Carbide (CCC-SC)
FLEXIBLE BLUE SERIES STANDARD: 5-8 lb/cu.ft. (80-128 kg/cu.m)
Same medium Density foam as Red Series with a softer, more flexible blue coating. Ideal for use in lines with major reductions in cross sectional area and short radius bends. (Please Corrosion Control Products Company for extreme diameter reduction applications.)
3A Blue Plain Spiral (BPS)
3B Blue Silicone Carbide Spiral (BSSC)
3C Blue Plain Criss Cross (BPCC)
3D Blue Silicone Carbide Criss Cross (BSCCC)
MAXIMUM CLEANING SERIES: Various Foam Densities & Coatings
Maximum cleaning series are available in various densities and designs. The Super Javelina is totally covered with wire brush straps in a slight spiral pattern. The Power Brush, totally coated with wire brush straps in a straight pattern design, allows sufficient by-pass to clean the brushes and suspend debris ahead of the cleaner. Both the Super Javelina and Power Brush cleaners are designed for long runs. The Shark is totally covered with Silicone Carbide chips and is designed for shorter runs. The Stud cleaner has steel studs embedded in durable foam for removing hard scales.
(Use caution in using maximum cleaning series where short radius bends, reduced cross sectional conditions, and low flow rates are present).

Information on Polyurethane Foam Pipeline Cleaners
Can be molded in diameters from 112" to 108" (12.7 to 2743 mm) by increments of 1/8" (3.17 mm). Standard length from base to shoulder is approximately 1.5 times diameter. Other lengths available upon request.
Wire brush designs are available with light or heavy wire. Can be used bi-directionally. Standard brushes are made from steel hardened bristles. Stainless steel or brass bristles are available upon request.
Silicone carbide designs are available in fine, medium or coarse grit.
No additional charge for: Polypropylene 16" and over, Double Dished, or Double Nose design.
Additional charge for: Cleaners with transmitter cavities, additional lengths, steel cable ropes instead of polypropylene, and for polypropylene ropes on designs under 16" are at extra charge.
Custom designs available for the majority of pipeline operating conditions.
