The CYL light-density bare swabs are constructed of light density foam and are NOT coated with polyurethane elastomer on base as with the LB series. They are primarily used for drying and sweeping of loose debris. However, other functions include using as a gauging pig for determining internal pipe conditions prior to extensive pigging, using as a sealing pig behind a stuck pig, using for batching and product removal, as well as, using in concrete pumping trucks between batches.
Standard light density foam is 1.2 lbs/ft3 foam. Various light density foam options are available upon request.
WARNING: This type of pig should NOT be used where extreme low pigging pressures or volumes are present because the propelling medium may permeate through the foam, rather than push it through the line. Options and other configurations include bullet nose, double-nose, pulling rope or cable, customized diameters and lengths for special pigging applications.
