Steel Pigs
Steel-mandrel pigs are a more long-term, long-life pig. They consist of a steel mandrel body with replaceable sealing elements (cups and discs). They can also be equipped with abrasive components (brushes and blades) for removing deposits on the interior pipe wall. The advantage of steel pigs is the ability to replace the wearing components.
Following are the most common styles of steel pigs with model numbers and best suited applications.

Batching, Gauging & Displacement Pigs
2" - 48" Conical-cup pigs (2 cup design with or without brushes or blades. A versatile pig with limitless configurations for almost any pigging application)
Description: Sturdy carbon-steel body equipped with easily replaceable conical cups and steel brushes or urethane blades mounted on wear-compensating flat springs, providing 360o coverage of internal pipe surface. Capable of being fitted with gauging plate machined to specifications. Designed to be versatile with the ability of being fitted with two, three, or four cups and spring-loaded brushes or blades in field with ease. 2" through 14" are center-rod type and 16" through 48" are bolting pattern configuration.
Design Function: The design allows this pig to perform all operations of pigging, including filling, dewatering, batching, cleaning, gauging, and product removal. Equipped with conical cups, pig can negotiate up to 15% reductions and deformations.
Options: Carbon steel, stainless steel, or aluminum body; cups manufactured from polyurethane or other elastomer compounds for special services; aluminum or steel gauging plate of varying thickness, with or without slots; two-cup, three-cup or four-cup pig design; carbon steel, stainless steel, prostran brushes, or polyurethane blades; transmitter or pinger cavity; magnets; configurations can be modified to include discs for increased sealing capabilities; customized dimensions for special pigging applications.
