Galvanized stud bolt
Galvanized stud bolt
(OP)
Hi all,
I have a material specification where the stud bolt used for steam, condensate and hot-water at 300 ºC and 20 barg is CK35 galvanized.
I would like to know if the stud bolt material given is ok for these services.
On the other hand, is it possible used the galvanized piping, fittings, bolts, for high temperature services??
Thank you very much,
Regards,
Rocio

I use hot dipped galvanised bolting without any problem at 192 deg c, not sure about 300 though.

But, is not it better to use galvanized bolts than black carbon steel bolts for this service? and, is not it better the behaviour of the galvanized bolts than black carbon steel under the same environment conditions?
On the other hand, I would like to know if the bolts whose material is A 193 B7 is carbon steel or alloy steel because I don´t understand well the ASTM rule.
Thank you very much,

RE: Galvanized stud bolt
Your temperature would normally require an alloy bolt like the A193 B7 or a A193 B16.
What piping code are you installing this piping under?
