Coated Super Havelina Polly Pig Super Havelina Polly Pig Havelina Polly Pig 142 Figure 7-7. Bullet-shaped pigs. (Courtesy of Knapp Polly Pig, Inc.) Inexpensive Foam Sweege Pigs are now available to temporarily remove oxide that cause red water. The standard Sweege Foam Pig StyleV-B, is an inexpensive, ex- pendable Knapp Polly-Pig s of extremely soft foam designed specifically for temporary sweeping of a line to eliminate oxides that cause red water. The are easily inserted into water mains by hand, require no special devices, no line shut offs, and are propelled by nor- mal water pressure. , , Figure 7-8. Foam sweege pig.

The diameter of Polly-Pigs is usually one and a half times the length. As a rule, ~/8" is added to the pig body size for coating. Some pigs with diameters less than 6" have mesh for internal reinforcement. Some are equipped with a rope on one or both ends for ease in handling and pulling. Dished ends add to the effective fluid removal while pointed ends are used for bi-direc- tional changes. The ends may be either shorter or longer for extreme valves or launches. They also come in either soft or hard for variations in density (Figure 7-9), which is measured in pounds per cubic foot. Some styles of Polly-Pigs made by Knapp are de- scribed in Figure 7-10. They are color-coded by type of cover for identification and some are criss-crossed.
