Percentage of RT As Per ASME B31.3

[Mukul]

Dear Experts,

Can anybody help me by telling the RT percentage in ASME B31.3 ? Is the percentage is mentioned in the code or not ?

Regards,

Mukul Samad

[George Dilintas]

start reading 341.4

for normal fluid services, RT is 5%.

For severe cyclic conditions, it is 100%

For elevated temperature service there is a requirement for the NDE during the fabrication of the pipes in the mill. 100% RT on longitudinal or spiral welds if base metal is Pno 4 or 5

Hi Mukul,

It's a project requirement, ASME B31.3 will indicates the fluid service categories.

Percentage of radiography is normally mentioned in the NDT requirements of Client/Welding and NDT Specification.

Also, you can refer project (PMS) Piping material specification / Piping line list / Isometric Drawing.

The requirements are mentioned in the approved line list is the final and follow the same.

Thanks

Ok.I got your point. So for category M fluid service what will be the RT percentage?

We can't decide this,  Piping  Design / Process Engineering team decides the percentage requirement of RT and indicated the requirements in the piping line list.

I believe we can't simply follow ASME B31. 3.

[atul khatri]

Minimum  NDT % is governed by applicable fluid service as per chapter VI of ASME B31.3.

Client can always ask for more stringent requirements.

I am attaching the NDT extent as per chapter VI for quick reference.

The minimum% NDT is governed by the applicable fluid service per ASME B31.3 Chapter VI.
The client can also request less stringent requirements, based on their own criteria and interests, this is totally valid, in the vast majority of countries the Code does not have legal implications, these criteria can be described in contracts, I mention it, since I am in a paper mill project, where most of the pipes carry water or water with pulp and therefore the interested company only requires 20% RT in the welded joints of the pipe systems. In other words, only some parts of the Code apply, it is only a reference, it is not mandatory in all its sections or parts.
