About Our Company
Pipeline Pigging Specialties Ltd. is a 100% Canadian manufacturer of Urethane pipeline cleaners, known to the trade as “Pipeline Pigs” or “Poly Pigs”. Pigs are designed to remove any kind of product build up, gauge pipe, dry water or change line product, and more, we can accommodate almost all of your application requirements. Pipeline Pigging Specialties has been an independent business since 1994 and growing every year. With over 30 years of combined experience, expertise, research and development. We pride ourselves on quality high grade materials and service in Foam Pigs, Poly Urethane Pigs, Specialty Urethane and Specialty Foam Products. We understand that every pipeline was built different and has it’s own needs, therefore customizing to accommodate those differences is a big part of our structure. Our goal is to keep a close working relationship with all of our customers and supplying knowledge & products you and your changes in the future.
What Is A Pig?
A pig is a device inserted into a pipeline which travels freely through it, driven by the product flow and/or other applications to do a specific task within the pipeline. These tasks fall into a number of different areas: (a) Utility pigs which perform a function such as cleaning (i.e. corrosion, wax build up from crude and/or other matter which may slow the production of the line), batching (either changing the line content or running a cleaning fluid between two pigs), filming (lining the pipe walls with a corrosion inhibitor), separating products in-line, de-burring newly welded lines, hydro testing or dewatering the line; (b) Inline tracker pigs which electronic sensors have been inserted inside the pig then used to provide the location of damaged pipe or other blockages in the line; (c) Steel body construction pigs with aluminum plates for de-burring a newly constructed lines followed by gauging the pipes roundness after burying it in the ground to ensure the back fill has not damaged the line, and for proving a de-commissioned lines.
Pigs are chosen specific to each line and applications involved. It is important to set the objective and define the task that the pig has to perform. The pipeline layout will dictate the geometry of the pig largely. The pig must be long enough to span features such as wyes and tees yet must be short enough or flexible enough to negotiate bends. Changes in the internal line diameter will influence the design effort required for the pig. In summary, the correct type is chosen for the task but then the pipeline design and operating conditions will affect the actual design of the pig.
The pigs shown here are samples of assorted coating applications to Polyurethane Foam Pig products which are manufactured in variety of densities (super soft, like chair cushion to medium density, like a nerf ball to hard density, comparable to cork material) Also shown is an assortment of styles and durometers of Poly Urethane pigs (urethane is a material in between plastic and rubber – it has more flexibility than plastic and has a longer wear resistance than rubber) There is a wide variety of features to offer in urethane, namely style and durometers. Durometers determine the hardness of the urethane, we range from as soft as a men’s shoe heal to as hard as a plastic pen.
Pipelines represent a considerable investment on behalf of the operators and can prove strategic to countries and governments. We are generally accepted as being the most efficient method of transporting fluids across distances. In order to protect these valuable investments, maintenance must be done and pigging is one such maintenance tool.
