NDT HDPE

[JR 166]

Hi,

I need to know what the mandatory standard is to perform non-destructive tests on HDPE, and what tests they would apply, I understand that ultrasonic testing can be done, but I need a code to indicate it, could you tell me what code speaks about it.

Please, I need your experiences to make the best decision

It all starts with (and probably is determined by) your code of construction. Do you have that information available?

If not, can you share a bit more on the application?

the hdpe will be for a project in a refinery (process pipe), which will be buried to supply water for a fire system, the HDPE is SDR 11, IPS = 6 "

What is the design code, aka code of construction? ASME...? NFPA?

 

[JR 166]

ASME

 

[XL83NL]

And which section of ASME? B31.3?

I'm not familiar with how well it covers testing ,but I think you're going to want AWWA C901 or C906 for polyethylene pressure pipe. ...and for firewater, our insurer requires it be FM approved pipe and fittings.

Fire water HDPE piping systems in the substantial number of jurisdictions in States of the USA where we have installed them are hydrotested only. They would be classified under B31.3 as Category D and again be hydrotested only.
