RE: stainless steel sparking

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Yes stainless on carbon or stainless can cause sparking.  

In a highly combustible atmosphere you should consider brass bolts.  Another possibility is Loctite.  Loctite is an epoxy that could provide adequate insulation on stainless steel to prevent sparking.  I am not sure if there is any research on this.  The API might be able to help on this.  Also consider using special tools.  The tools can be a source of sparking.  It is the static electricity during installation that is the problem.

This is follow up question to the stainless to carbon steel question thread
of a few days ago.
Will stainless steel rubbing against carbon steel (or stainless steel) cause
sparking? Sparks would be a problem since it would occur in a rich solvent
atmosphere. I myself cannot think of a reason why it won't cause sparking
but someone asked me this question and I just was wondering if anyone else
could explain.
