Pipeline Pigging Guide
What Is Pipeline Pigging? The Complete Australian Guide
Pipeline pigging is the practice of inserting a device called a 'pig' into a pipeline and propelling it through the line — using the existing product flow or an external mediu
Types of Pipeline Pigs Explained: The Complete Guide
There are two main categories of pipeline pigs: utility pigs (foam pigs, disc pigs, cup pigs, solid cast pigs, dual diameter pigs, and gel pigs) used for cleaning, dewatering, batchin
How to Select the Right Pipeline Pig: A Practical Guide
Selecting the right pipeline pig requires seven key inputs: pipeline internal diameter, product type, pipeline geometry (bend radii, valve types, bore changes), debris type and volume
Foam Pig Density Explained: The Complete Australian Guide
Foam pigs are available in four standard densities: low density (16–32 kg/m³) for line proving and drying, intermediate density (40–56 kg/m³) for light cleaning and batching, mediumd
Pipeline Commissioning: The Complete Pigging Sequence
Pipeline commissioning pigging follows a 10-step sequence: (1) gauge plate run to confirm bore, (2) flood pig, (3) hydrostatic pressure test, (4–5) dewatering passes, (6–7) cleaning p
Pipeline Dewatering After Hydrostatic Testing: Best Practices and Pig Selection
Pipeline dewatering after hydrostatic testing uses a sequence of foam pig runs to progressively remove test water from the pipeline bore. The standard sequence is: low density bare fo
Gel Pigging vs Foam Pigs: When to Use Each
Foam pigs are solid physical objects that sweep debris and liquid through the pipeline bore — they are the right choice for line proving, dewatering, drying, and general cleaning. Gel
Pipeline Integrity Management in Australia: What Operators Need to Know
Pipeline integrity management in Australia is the systematic process of identifying, assessing, and managing threats to the safe operation of a pipeline. For gas and liquid petroleum
Australian-Made Pipeline Pigs: Why Local Manufacturing Matters
Australian-made pipeline pigs offer three critical advantages over imported alternatives: lead time, technical support, and supply chain resilience. Royal Poly Products manufactures t
Case Studies
Progressive Pigging of 16” x 89km Timi Gas Pipeline
Royal Poly Products was selected for the progressive pigging campaign of the 16” x 89 km wet gas pipeline as part of the Timi Field Development, supporting Shell and its partners.
Emergency Foam Pig Deployment – Scarborough Wet Buckle Recovery
Following a wet buckle incident during offshore pipelay operations on the Scarborough Project, a section of the subsea gas export pipeline was flooded with raw seawater
Bespoke Foam Pigs for Large-Bore Pipelines with Over 100 Bends
Royal Poly Products was engaged to design and manufacture a bespoke foam pig capable of navigating over 100 consecutive 90-degree, small radius bends in an onshore pipeline system.
