The EMT Bi-directional Pig has a wide range of applications！
The EMT Bi-directional Pig has a wide range of applications, making it an invaluable tool in pipeline maintenance:
Cleaning and Sweeping: These pigs are deployed initially to sweep the pipeline, removing impurities and ensuring a clean interior for fluid transportation after pipeline construction and pre-silicon processes.
Gas Exhausting and Dewatering: Before pipeline hydrostatic testing, the bi-directional pigs are used to exhaust gas, and after testing, they aid in dewatering, preparing the line for operation.
Inspection for Errors: These pigs serve an important inspection role by checking for roundness errors, verifying the accuracy of the live ball valve's position, and ensuring the correct pipeline diameter upon valve opening.
Weld Flash Removal: Specifically at joint locations, bi-directional pigs are employed to remove weld flash, enhancing the integrity and flow efficiency within the pipeline.
Regular Maintenance: The pigs play a crucial role in regular or irregular tasks such as ash discharge, paraffin removal, descaling, and water treatment in used oil and gas pipelines. This maintenance ensures the continued functionality and longevity of the infrastructure.
Fluid Separation: When different fluid mediums are transported in a single pipeline, bi-directional pigs can be used as isolators, effectively preventing cross-contamination.
Pipeline Coating: Applying anticorrosive coatings is an essential aspect of pipeline maintenance. Bi-directional pigs can precisely and evenly apply these coatings along the pipeline walls, protecting the metal against corrosive elements.
