Re: code for NDT in Hydropower plant
In order to help you, you have to be a little more specific in to what you want to do! There are many different codes that are applicable to power plant.

Thank you Mr. Michel.
Please help me by advice which code or spec. maybe used to NDT examine the penstock of Hydropoer Plant, for example. I think, ASME code B31.1, B31.3 or B31.4 are not really proper for this case. Thanks for your soon reply

Dear Mr. Jawed Ahsan,
Thank you for your response. But I'm affraid that using B31.1 in this case is not very suitable as the scope I refer to below:
100.1.2 Power piping systems as covered by this
Code apply to all piping and their component parts
except as excluded in para. 100.1.3. They include but
are not limited to steam, water, oil, gas, and air services.
"(A) This Code covers boiler external piping as defined
below for power boilers and high temperature, high
pressurewater boilers in which: steam or vapor is generated
at a pressure of more than 15 psig [100 kPa (gage)];
and high temperature water is generated at pressures
exceeding 160 psig [1103 kPa (gage)] and/or temperatures
exceeding 250°F (120°C)."
I hope I may receive the advice in more detail.
Thank you very much.

Dear DAO DUY DUNG
My Friend Tuberosa give me two norm-project on hydraulic machinery but in the meantime i see that you are interesting in penstocks-inspection. I remember that our electricity company have specification on penstock inservice inspection. If you are yet interested I will reserch for you that specification, but attention, they are in italian!!
I look to your response, ciao, Ezio

nresolved asset integrity problem in the industry. Current methods for measuring wall thickness with liftoff, without removing insulation, all have severe limitations. Eddyfi introduces Lyft — a reinvented, high-performance pulsed eddy current (PEC) solution. The patent- pending system features a state-of-the-art portable instrument, real- time C-scan imaging, fast data acquisition with grid-mapping and dynamic scanning modes, and flexibility with long cables. It can also scan through thick metal and insulation, as well as aluminum, stainless steel, and galvanized steel weather jackets. Who else but Eddyfi to reinvent an eddy current technique and redefine CUI programs. Got Lyft?
