ansi use of gavavanised bolts
tabi (visitor)22 jul 02 20:54
can galvinised bolts (a320)be used on duplex stainless steel & 316ss piping where the chances for moisture are present during the years by means of raining (30 days a year) & fall of temperatures affacts ( evening to morning for the period of approx. 30-40 days)?.
if some has the same experience, please can he mention the corrosion effects (bi-metallic corrosion) on the zinc coated bolts & nuts?. we are expecting severe consumption of the zinc coating due to higher cathodic to andic area ratio.
