AS1579 - Arc welded steel pipes need for NDT?

[rgvrider]

Hi,

For people familiar with AS 1579.

I'm looking at using this standard for a pump application with ~250 m of head, ~1000mm ID pipe. I haven't used this standard before (much more familiar with AS4041) so would like some clarification on what I seem to be reading.

Is my understanding correct that if the pipe is to be Hydrostatically tested, there is no requirement for any NDT for welds? This seems to be my understanding, but it seems very risky?

Cheers

You might want to read through thread378-258939. While it doesn't answer your specific question about the standard, it provides some good information about the overall subject.

The degree of NDE or hydrotesting is dictated by AS 4041,AS 2885 or AS2556 or whatever standard you are using for the design, installation and testing of the pipeline.
