|
|
|
|
|
Steel Pigs Steel mandrel pigs' sizes ranging from 2" to 48" nominal pipe diameter with configurations including standard cup, disc, conical, multi-disc, and articulated pigs. All of which cab be fitted with wire brushes or paraffin-removal blades. |
|
|
Cup and Disc Pigs Equipped with cups and/ or discs, these pigs are primarily used for evacuating air and liquid during hydro testing, routine batching, displacement, and product removal. Gauging plates can also be added to prove pipe roundness and minimum bend radius. Multi-disc pig design allows reversing pigging direction. |
|
|
Cleaning Pigs These rugged pigs are equipped with circular brushes or block type brushes or blades mounted on wear-compensating springs. They are used for cleaning rust, mill scale, sand, wax, organic growth, mud, oxides, and other foreign debris. |
|
|
Criss-Cross Pigs This design is typically bullet shaped and constructed of medium or high density foam with a polyurethane elastomer coating applied in a single-spiral or criss-cross pattern. |
|
|
Wire Brush or Plastic Bristle Pigs Equipping the pigs with wire brushes or plastic bristles provides maximum scraping and cleaning of pipelines in a variety of applications. Standard configurations include barber pole or total coverage. |
|
|
Conical Cup Pigs Suitable for the entire range of pigging applications, this versatile design allows for the same pig body to be equipped with 2, 3 or 4 cups or discs and with or without spring loaded brushes or blades for cleaning operations. |
|
|
Spares and Accessories In addition to complete pigs, spare components including cups, discs, blades, springs and other accessories can be manufactured to fit all styles and makes of pigs. |
|
|
Silicon Carbide Pigs By adding silicon carbide in loose grit or strap, moderate scraping action can be achieved. |
|
|
Configuration Options Pigs Unlimited, Inc. manufactures many optional foam pig configurations, such as double-dish, double nose, double length, totally coated, and pulling rope or cable. A transmitter cavity can be incorporated for pig tracking applications.
|
|
|
Product Displacement Pigs The key to the system is in the design of the process displacement pig, which with its multiple discs, virtually eliminates bypass. The pigs is capable of spanning full-branch tees, negotiating full-port valves, and 1.5 diameter bends. The pigs can be manufactured to any diameter, length and configuration as well as from various compounds to be compatible with different products or applications.
|
|
|
Solid Cast Pigs Solid cast pig with three guide discs and eight wiping discs. Effective for product displacement where cross examination and the need for dedicated lines are minimized. Neoprene, urethane, viton and other rubber compounds. Customized sizing of pig dimensions.
