Re: [MW:28348] testing of inaccessible welded joints

It is not possible since all of joints butied.

Does anybody know about high resolution MFL would be useful in evaluting of joint

Regards.

Do you have any file for presenting this method?

I said in previous emails, pressure testing may not detect some rejected defects that don,t cause leak.

Borodcope you can identify internal defect. otherwise pressure test

Thank you for responding but our line is long& we want to know about internal defects and visual in that situation doesn't have good sensitivity.

Actually, I am wondering about mechanised ultrasonic that syncronised with crawler.

If you know any equipment or company that have simillar technology.

Regards.

for smaller length, a surface inspection with boroscope can be possibly made. Now a days boroscope with robot manipulator (pipe crawler) also available which can be remotely controlled although a costly matter.

The above system can be used upto 500 mm however diameter restriction is applicable.

Shared more details about the joint types, pipe dia length etc would be better for the understanding.

Thanks & regards

Dear Kumar.

this line is piggable but I don't think the pig with considering pf it's velocity don't have ability to scan welds?if you know information or experience, please let me know.

pressure testing can only detect defects that cause leak or rupture, and other rejected defects can be undetected.

Regards.

If it is a pipe line, best option is to do hydro test with 1.25 times of the working pressure to ensure the integrity 

Also can go with ultrasonic pig in case of pig possible lines

Thanks and Regards

Dear All.

Does anybody know there is NDT method that can inspected welded joints which are buried and not accessible?our concern is about finding of construction defects either surface and internal that have a good detect ability for linear ones particularly Transverse Crack.

Regards.
