Resin leakage at the bottom of the screen changer in the polypropylene extrusion granulator (Nippon Steel)
Thread Content
I was wondering if there is any solution?
In the image above, leakage in static seals is usually caused by a failed gasket; take a close look at the internal structure diagram
Are there any drawings? We’re from Kobe Steel; let’s see if they’re the same or not
The drawings are probably lost. I don’t know if it’s filled inside.
Is it solved? We’ve encountered similar problems as well, but the leakage isn’t as severe as yours
First, you need to identify the source of the leak – whether it’s at the sealing surface, in the form of pores, or in the welds – before you can proceed with further assessment
