In our Swedish utilities do we normally use UT for all advanced volumetric testing. UT is often combined with ET in order to be sure to detect all surface breaking defects.
When UT is applied for primary systems, is it in the absolute majority of the cases mechanized systems that are used...
One interersteing aspect is that the AREVA-NP EPWR is a 1600 MWe plant, present being erected in Finland is approximately 20 % more expensive than the AP1000 but gives 40 % more energy, thus being more cost effective.
Concerning China, as far as I know, they are planning on building more than 20...
Depending on geometry and thickness, possibility to fasten the object etc, FSW might be used.
FSW stands for Friction Stir Welding.
An introduction can be found using the links below:

First off all – there is always a risk of cracking when welding cast iron.
When preparing the damaged area, use arc gassing in order to obtain a good welding geometry.
This method will prevent carbon from being smeared on the surface and therefore reduce the risk of cracking when weld material...
After a discussion with one of my friend who is working at a company manufacturing these type of components for the pulp industry, I was given the following recommendation, in accordance to there normal practice:
They use thermal coating, but coating using plasma also possible (plasma...
This is one case we studied during my traning to become an IWE.

16MnCr5 is a case hardening steel in accordance with European Standard (EN).
Carbon 0.16, Manganese 1.00, Chromium 1.00
If there is a need for machining, consider using 16MnCrS5 with a specified amount of Sulphur.
One method of examining the need for elevated working temperature is using the European standard 1011-2:2001.
Calculate the carbon equivalents (CET).
CET = C + (Mn + Mo)/10 + (Cr + Cu)/10 + Ni/40 (%).
It applies to the following range of concentrations (percentage by weight):
- Carbon 0,05 to...
Is it anybody out there who knows the specific compositions for API SPEC 5L materials?
I am specially interested in X60, X65, X70 and X80.
If some do have information of > X80, information is gratefully accepted.
