Topaz offers many types of pipeline pigs to satisfy diverse cleaning, dehydrating, batching, and gauging functions.

Polyurethane foam pigs are recognized in all piping industries as the most economical and durable product available for the effective cleaning and dehydration of pressurized piping systems. We sell low, medium, and high-density foam pigs for increased service life in various length-of-run categories up to twelve hundred miles. All densities are available in a variety of bare, rubber-coated, abrasive, and cavitied configurations for use in drying, wiping, scraping, and tracking operations. These foam pigs will pass through 90° ells and reduced port valves. We can supply foam pigs for any nominal pipe size, as well as custom units in special shapes and sizes up to nine feet in diameter.

Solid cast polyurethane pigs in various durometers are available in 2" through 30" pipe size. Disc, cup, or disc/cup combinations are designed to provide effective removal of liquids or product from pipelines. Their superior sealing capabilities allow navigation of out-of-round pipe and pipe runs with varying wall thicknesses.

Besides polyurethane foam and solid cast polyurethane pigs, inflatable polyurethane pipeline spheres and steel mandrel pigs with replaceable polyurethane cups, discs, and bolt-on accessories, such as wire brush assemblies, can also be supplied.
