Pipeline Engineering
Foam Pigs
Foam Pigs are used in pipelines for liquid removal, swabbing, drying, product separation, cleaning and as part of progressive pipeline cleaning campaigns.
These foam pigs are ideal for all pipelines, including complex piping systems with tight radii or mitred bends and pipelines where significant variations in internal diameters exist.
Foam Pigs - Types
- Bare Foam Pigs
- Single Spiral Foam Pigs Criss Cross Foam Pigs
- Criss Cross Abrasive Foam Pigs Fully Coated Foam Pigs
- Wire Brush Foam Pigs
- Total Wire Brush Foam Pigs
Applications
- Proving
- Swabbing / Wiping
- De-watering
- Drying
Sizes Available
- 2” to 60” - Foam pigs are supplied for all pipe sizes
Density Range
- Foam pigs are supplied in all industry standard densities.
- We can adapt our foam pigs for different operational requirements.
Pipeline Spheres
Pipeline Spheres are predominantly used for batching or separation operations in pipelines and removal of liquids from gas pipelines.
Pipeline spheres are extremely adaptable and ideal when negotiation of short radius bends in pipelines is required.
Applications
- Liquid Removal Batching
- Meter Proving Automated Pigging
Spheres –
- Types & Sizes Available
- Solid Spheres - 2” to 12” Inflatable Spheres - 3” and above
Uni-cast Polyurethane Pigs
Uni Cast Pigs are produced from our high grade all-polyurethane formulation which gives them excellent chemical and abrasion resistance.
Typically, Uni Cast Pigs are used as sealing pigs to remove debris and to keep pipelines clear of deposit build-up. Uni Cast Pigs are also used for batching operations. They do not require maintenance and are designed to be disposable, making them the preferred type of pig when metal bodied pigs are unsuitable.
The flexibility of our Uni Cast Pigs makes them ideal for use in complex pipeline geometries and small diameter pipelines, typically found in process plants.
Applications
- Product removal
- Batching
- Hydrostatic testing
- Debris removal
- Displacement
- Commissioning / Decommissioning
Sizes Available
- Uni cast pigs are supplied for pipeline sizes ranging from 2” to 14” and larger where required
Density
- Depending upon operational parameters Solid Cast Pigs are supplied as 65A to 75A shore hardness.
Metal Bodied Pigs
A market leader in the design and manufacture of metal bodied pigs, with our expertise having been gained over many years of operating in the Oil and Gas sector.
In-house expertise means that we can produce metal bodied pigs to meet the specific requirements of pipelines where they will be used. This is achieved by designing these
Metal Bodied Pigs with a combination of components including Cups, Discs, Brushes, Plough Blades, Gauge Plates, Magnets and Tracking Equipment.
Our Metal Bodied pigs are used during all phases of a pipeline life cycle
- Pre-commissioning
- Commissioning
- Production
- Decommissioning
Metal Bodied Pigs - Types
- Uni-directional Standard Cup Pigs
- Uni-directional Conical Cup Pigs
- Bi-directional Disc Pigs
- Cleaning Pigs
- Batching / Separation Pigs Gauging Pigs
Sizes Available
- Metal Bodied Pigs are available for pipelines ranging from 6” - 60”
- Other sizes are available on request
Specialty Pigs
designs and builds specialty pigs to meet the specific pigging requirements of complex and demanding pipelines. This is achieved through analysis of the existing pipeline issues including assessment of all pipeline features.
Using this information we design, prototype, test and produce bespoke pigs for specific pipeline pigging requirements.
Using specialist pigs developed this way enables innovative and highly effective solutions to be provided, as well as ensuring safe and efficient passage of the pig through a pipeline.
Computer Aided Design
- State of the art 3D CAD design capability allows us to initially develop specialty pigs and simulate their functionality.
Pig Development and Testing
- Specialty pigs are routinely tested in our purpose built test loops. This process allows analysis of performance against the predetermined criteria. It also allows further design refinement to be implemented to benefit specialty pig performance when in fully operational conditions.
Specialty Pig Manufacture / Assembly
- On completion of successful trials, specialty pig designs are transferred to our computer aided manufacturing system for production and assembly.
Specialty Pigs - Types
- Multi-diameter Pigs Articulated Pigs Isolation Pigs
- High Friction Pigs
- Descaling / Dewaxing Pigs Powder Removal Pigs Extended Length Pigs Bespoke Operational Pigs
