Rechniques for checking internal surface of piping 12" and 16" for natural gas supply

[Mohammed Ghani]

Dear Experts,

please let me know there is any technique available for checking internal surface of piping (in service fuel natural gas)

And also if there is nay technique for checking internal surface of piping during shutdown please let me know.

Thanks and Regards, ?

Dear friend,

For checking internal surface of piping, we can use Borescope or Fiberscope. This is an instrument, which is available in market or vendor places.

Dear friend,

snake eye -iii is one type of instrument  used to check internal surface defects,welding defects.vt-level-ii engineers used that instrument.you can approach ndt agency to collect  that instrument and inspect that piping.

Thanks and regards.

Dear,

its a 40 mtr. continous in service pipe line. i need two options.

1. with out shutdown any chances of internal surface inspection?.

2. with shutdown what are the various types of instruments available for checking internal surface of piping of 40 mtr. length.

Thanks and Regards,

Mohammed Ghani.

Dear Sir,

You can use UT thickness survey and LiXi profiling to monitor the piping while in service. Once offline, during shutdown Boroscopes may be used.

for a continuous pipeline you can use LRUT online and again boroscope offline.

Hello

 

You can use a NDT technique called ultrasound guided waves (UTGW)

 

This technique can detect a serious kind of defects in pipelines, internal and external. Depending of pipe conditions, this NDT can inspect even 50 meters of pipeline in just one test.

 

As is based in ultrasonic principle, this use longitudinal and torsional waves to detect indications which are categorized quantifying the transversal loss of area in pipe. As complement, then you can use single beam of ultrasonic thickness measure to check any indication

 

This can be used with pipeline in service

 

Attached you can find a little information about this NDT

 

There are a lot of services in NDT which offer this one
