Good afternoon all,
Does someone knows good literature/books regarding the failure mechanisms (example blistering, delamination, corrosion, cracking) of FRP pressure vessels with photo's ?
For metallic pressure vessels we have for example the corrosion atlas, is there something similar...
May i ask why you dont agree?
According ASME IX , QW 256, T qualified is an essential variabel (see QW-403.8). QW403.8 refers to QW-451, which states range base material thickness T as 2*T.
All thanks for the reply.
As i understood the deposit thickness t is not similar to the base material thickness T. According to m the base material thickness T should withon the limits on the PQR. When the base material is thicker as in the PQR we might have a difference in material structure...
Dear Don56,
Thank you for your response.
The in this case the flange face has been repair welded by a company which holds a PQR (groove weld) which is valid for material thickness T=25mm.
In practice the component has a material thickness T=45mm. The PQR is normally not valid for this material...
Hello all,
Can the restore welding/build up welding of a flange face be seen as fillet weld?
This in context of the ASME IX QW202.3 (range of qualification for material thickness).
