The general rule for the cleaning requirement of any pipeline is that the cleaner the line the better the inspection result and less chance of any problems during inspection. Cleaning of a pipeline can be achieved in many ways, normally hard or soft bodied cleaning pigs would be run through the line until the pipe is cleaned to the desired level.

Polyurethane pigs
We supply 4 basic types of polyurethane foam pigs: drying, wiping, cleaning and scraping, all manufactured from high quality open cell polyurethane foam in sizes from 2 inches to 144 inches and coming in four different densities.
1 – 2 lb/ft3 Drying, Cleaning and Scraping.
5 – 8 lb/ft3 Regular Wiping and regular Scraping.
9 – 10 lb/ft3 Heavy Wiping and heavy Scraping.
Up to 20 lb/ft3 Special applications - Batching, Special

Cleaning and Scraping.
All polyurethane foam pigs are able to negotiate 90 degree Ells, Tees, Valves and pipe internal diameter changes. They will travel in almost any piping system with adequate flow and volume to move the pig.

Solid Cast Pigs
Pigs of solid cast polyurethane with multiple discs and/or cups of various durometers to suit specific applications. They give a good quality seal which make them ideal for product batching, line displacement and product evacuation . They also can be used to control paraffin build up in crude oil lines.

Spheres
Spheres are available in size 2 inches to 36 inches and are used for separating batches, hydrostatic testing, dewatering and line maintenance with corrosion inhibitors. Different durometers can be used when additives are present in the line.

Steel Mandrel pigs
Can be manufactured in sizes 2 inches-48 inches and are used for cleaning, batching and gauging in Uni or Bi-Di modes by using different disc and cup arrangements. When used for gauging an aluminum disc is added. Cleaning pigs can have spring loaded brushes and/or scrapers attached to the pig body for various applications. Steel mandrel pigs are mainly used for batching, displacement, hydrostatic testing, paraffin removal and cleaning.
