How to protect Serration of Flanges during Hot dip galvanization

[senthil aravind]

Dear Sirs,
Presently we are doing hot dip galvanization of pipe spools where we
have to protect the serration of flanges during galvanization.

Can any body suggest what can be applied on serration to protect it
from adhesion of ZINC on serration.

Please Advise.

Regards
Arvind

Just apply silicon gel on the flange face , this is what they did in the galvanizing plant.
