Dear all, In cement plant, we have one air line made of 3 mm thick plate and diameter is 350mm. Now we has to install a butterfly valve DN350 in this line. As per valve supplier, we should use the flanges ISO 7005-1, PN10. But the thickness of flane is 28 mm. So is it feasible to weld this flange to pipe of 3mm thick plate. Or we should go for thinner flange then recommeded. Please advice as early as possible. Modified by Sanjay Sharma at Sat, Jul 22, 2006, 01:33:03 |

You can weld the flange to the pipe , despite it's thick.
Seem to be your air is at low pressure. The main concern about installing a buterfly valve is that it shall be open when tighting the nuts on screw , if not you can not open the valve after ajusting the nuts. Of course you can use a slim flange if you can get it The manufacturer tell you to use such flange as to macht with the rated pressure of the valve |
