Aqueous and Glycol based Gel Pigs

Alchemy produces a full range of Gel Pigs which can be used either alone, or in combination with conventional pigs, for debris removal, hydrotesting, dewatering, removing stuck traditional pigs, and condensate removal.


  • AGPP 2 – Aqueous Gel Pig
  • GGPP – Glycol Gel Pig
  • HTGP – High Temp Pig

AGGP 2 – Aqueous Gel Pipeline Pig

Alchemy AGPP2 (Aqueous Gel Pipeline Pig) is a solid gel pig system. It is used in lines where there is no requirement for hydrate suppression or where the pig will have to degrade within the pipeline system. This gel system is primarily used in oil pipeline applications. The gel is biodegradable so will be less stable and normally is used within 4 weeks of supply. After use the gel will breakdown or can be placed in a production stream where heat and low pH will destroy the gel pig. Alchemy AGPP2 is made in various diameters to suit pipeline requirements and is supplied in a custom built canister to the clients own specification.


GGPP – Glycol Gel Pipline Pig

Alchemy GGPP (Glycol Gel Pipeline Pig) is a solid gel pig which can be used in temperatures of less than 30 deg C to pig out lines and create temporary barriers for pipelines. The gel pig is manufactured in a former which is sized for the internal diameter of the pipeline. The pig and former are delivered to the pipeline site where the gel pig is inserted into the pipeline. The pig can be propelled with water, methanol, monoethylene glycol or gas. At the end of the pipeline the pig can be removed or sent to the production stream where it will dissolve with heat and low pH. This type of pig is also used to create sections of liquids within pipelines. Alchemy GGPP is resistant to biodegradation and so is ideally suited to projects where the time scale of deployment is not assured. The product is normally stable for up to 6 months in its original packaging. Alchemy GGPP is made in various diameters to suit pipeline requirements. 


HTGP – High Temperature Pipeline Pig

Alchemy HTGP (High Temperature Gel Pig) is a solid gel pig which can be used in temperatures of greater than 30 deg C to pig out lines and create temporary barriers for pipelines. Used in similar way to the Glycol Gel Pipeline Pig this Gel Pig system will be stable in temperatures in excess of 50 deg C. The gel pig is manufactured in a former which is sized for the internal diameter of the pipeline. The pig and former are delivered to the pipeline site where the gel pig is inserted into the pipeline. The pig can be propelled with water, methanol, monoethylene glycol or gas. At the end of the pipeline the pig can be removed through a pig trap receiver, small diameter outlets or sent to the production stream where it will dissolve with high temperature. This type of pig is also used to create a pack off to prevent sea water ingress or create sections of liquids within pipelines. Alchemy HTGP is presently being tested for biodegradation in long term tests. Please contact Alchemy for samples and further information on the exciting new development.
