PIPE LINE CLEANING PIG
SARA INDUS PRODUCTS manufacturing three types of Pipe Line Cleaning Pig, based on designs.
- PU Foam Pig
- Steel mandrel discs and cups
- Solid cast urethane
PU FOAM PIG
ADVANTAGES OF PU FOAM PIG
The PU foam pigs are usually made in the full OD of the pipeline. Foam pigs have the ability to negotiate short radius, ells and bends, miter bends, tees, multi-dimensional piping and reduced port valves. Length can be increased to allow maneuverability through large tees, some older Orbit valve designs and other type gate valves. PU foam pigs are great for sealing and light abrasion removal and can reduce in diameter up to approximately 35%.

STEEL MANDREL PIG
Steel mandrel pigs are built around a steel-constructed mandrel body. These 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.
There are three basic models available:
There are three basic models available:
- Cleaning Pigs
- Batch and Gauging
- Conical Cup
CUP PIGS
There are two types of cup pigs available in SARA INDUS PRODUCTS
SCRAPER CUPS
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.
CONICAL CUPS
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.

CONICAL CUPS
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.
GAUGING PIG ( OPTIONAL 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 hydro static 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, de-watering, separating, pre-commissioning, on-streaming, batching, cleaning, gauging, and product removal.
