Back ground music bahut jyada hai sir esko agli video me kam rakhe apki voice clear sunai nhi de rahi background music ki vajah se...

[@saputrajput9994]

Good

[@nileshkumar5439]

Good 👌👍

[@realroyalsantosh3861]

Thanks

Ideal pig speed 0.5 mtsec

[@realroyalsantosh3861]

The pig velocity shall be 2 to 3 Km/hour
The pig velocity shall be controlled by using the valve at the receiving end to maintain the back pressure 0.5 to 2 bar as required

[@amirjamal2598]

Thank you

[@talibansari8133]

What is the back pressure?

[@realroyalsantosh3861]

Back pressure is pressure it is used to maintain pig velocity

How to select gauge plate size for gauging?
Whether CGD mainline is piggable or not? If not, why we do piggaing in cross-country n why we can't CGD? Pls explain

[@jayantidey5644]

Gaugr plate size 95% of pipeline ID..CGD mainline always piggable....

[@amirjamal2598]

Gauge plate radial cutt lagta ha use depath ka calculation ha ya koi standard value

[@jayantidey5644]

Gauge plate usually 95% of pipeline ID rehta hai, usko aap 93%-96% tak ho sakta hai

[@borunkumarbiswas2013]

Pipe book ke bare mei btaiye sir PartA or part B

[@realroyalsantosh3861]

Ok

[@yakoobism]

Before you precleaned by pig, but after that you use gauge plate for what purpose?

[@realroyalsantosh3861]

Pipeline Gauging
Pipeline gauging is the process of locating and identifying internal defects such as dents, debris or other internal restrictions that affect the I.D. of the pipeline. Why is this important? The pipeline is designed to deliver a certain throughput based on a minimum diameter. It is in the best interest of the construction company to ensure the minimum diameter isn’t lost before finalizing the project. Pipeline pigs are used to accomplish this task, but not just any pig, the pig must be dressed with a gauge plate.
In the early days of pigging, gauge plates were made from steel. Today’s gauge plates are made from aluminum to avoid causing damage to the pipe walls.

[@realroyalsantosh3861]

How Does a Gauging Pig Work?
While traversing the pipeline, if the Gauging Pig passes through any obstructions or restrictions, the plate will show wear. Examining the wear on the plate and tracking the pigs location allows for isolating problem areas in the line. Once problem areas are identified in the line, the appropriate next steps can be taken to correct the issue, such as implementing a more aggressive pigging program to remove the debris, or making pipeline repairs to correct line damage causing the restriction.

[@jayantidey5644]

Gauge plate basically used for identifying pipe deformation, before EGP or ILI run

Hii

[@amirjamal2598]

App ka pass hydrotest procedure ka PDF file to please send me how to calculate speed of pig
Gauge plate acceptance criteria or rejected criteria

[@jayantidey5644]

Please mail your requirement I will provide u [e-mail]

[@amirjamal2598]

How to run pig in pipeline

[@realroyalsantosh3861]

By compressed air

[@jayantidey5644]

By Air, water or by product....For EGP & ILI water is best option.
