Fittings require an STL coating on the inner wall
Thread Content
Fittings require an STL coating on the inner wall; does anyone familiar with this area know something about it?
I don’t understand; is it an STL alloy coating?
Well, this can be achieved through thermal spraying, but that doesn’t help much~~~ I’d like to ask: what kind of connection method is used for these pipe fittings? For welding, the temperature of the heat-affected zone... only flange connection is possible~~~ and the DN value must be at least 80~~ (greater than, not greater than or equal to)
For butt welding connections, is STL Stellite alloy?
Stellite~~~abbreviated as STL~~~
