Steel Mandrel Discs and Cups
Steel Mandrel Pigs / Batching , Gauging , Cleaning & Displacement Pigs ( Cups / Discs )
Steel body equipped with easily replaceable cups and discs. Capable of being fitted with Brushes or blades and gauging plate machined to specifications. Primarily used for evacuating air and liquid before and after hydrostatic testing, routine batching operations, and product removal. Equipped with gauging plate, pig is used to prove roundness of pipe and to ensure excessive weld penetration or construction debris does not exist. Also used to prove minimum bend radius prior to intelligent pig use. This pig is able to perform all operations of pigging, including filling, dewatering, separating, pre-commissioning, on-streaming, batching, cleaning, gauging, and product removal.
Steel mandrel Pigs Types
Uni directional Cup Pigs
Scrapper cup Pig
Scrapper cup design allows for greater surface forces to be exerted on the pipe walls, especially in less than oval shape pipe while maintaining its ability to seal. These cups can reduce, on average, 15-20% of design diameter.
TWO CUPS SCRAPPER PIG
TWO CUP WITH BRUSH / GUIDE DISC SCRAPPER PIGS
Conical cup Pig
Conical cup allow for maximum sealing with minimum scraping to remove solids. This type is normally seen on gauging plate pigs and multi diameter and out-of-round pipelines. Conical cups can reduce up to approximately 30-35% and maintain adequate seal.
