It is meant & designed to clean newly erected pipeline before commission
It is specially designed to travel to a max distance without losing sealing with an eye on safety of the newly laid pipeline.
The pigs can easily negotiate during travel pipes of different diameters without losing its sealing ability.
The discs of the pigs are designed to ensure sealing ability thought-out its running length in both the directions
We Offer BIDI Pigs of sizes varying from 3” – 72” of different pipe schedule.
BIDI PIGS WITH BRUSH
These pigs are supplied with brush assembly both of metal & nylon bristles.
In case of pipelines with heavy wax/deposit on the inner side, these pigs with bristles are used to remove them.
The circular wire brushes are either fitted at the front portion of the pigs or at the middle of the pigs.
Spring loaded brushes are fitted on the circumference of the steel mandrel to effectively cover 360 degrees of the pipeline.
Bi-Di Magnetic Pig
The steel Mandrel Pigs are fitted with permanent Ferro Magnet along the circumference of the mandrel to attract loose metal particles even in dust form, or any metal objects, nails commonly found in pipelines.
The no of magnets & its spacing depend on the running length of pigging, types of particles normally found inside the pipeline, these are preferably cleaned after every run for cleanliness during subsequent run.
Bi-Di Gauge pig
The gauging pigs are fitted with aluminium gauge plates. These pigs are used mainly during commissioning of new pipelines to evaluate the circularity of the pipeline, for any welding penetration, etc..
When the pigs are received after a successful run the condition of the aluminium gauge plate will reveal the condition of the inner side of the pipeline,
The damaged caused to the aluminium gauge plate is an indication of the pipeline condition.
