What gaskets should be used between stainless steel flanges and carbon steel flanges? What bolts should be used?
It’s not a big issue; it mainly depends on the type of connection between the stainless steel flange and the carbon steel flange, and the gasket should be selected accordingly
It depends on what your medium is. . . . . .
This mainly depends on the type of medium and the medium pressure. . .
Does this even need to be considered? Gaskets are only related to the flange type and pressure rating, not to the material; wound gaskets are generally used
Oh, bolts aren’t a problem either; stainless steel flanges are also secured with ordinary bolts such as 35CrMo, 25CrMoA, and the like – stainless steel bolts aren’t necessary
The flange standards, nominal diameter, and pressure rating must be the same, and the sealing surfaces must be compatible； Gaskets are selected according to operating conditions; ordinary bolts can be used. The flange material is also selected based on the operating conditions; I’m not sure why different materials are needed
Gaskets are selected based on the medium, pressure, and type of sealing surface; they have nothing to do with the material of the flange. The same applies to bolts.
Such questions are rather vague; since the properties of the material and the operating pressure are unknown, it’s not easy to provide an answer. Generally speaking, metal wound gaskets have a wide range of applications. It depends on the medium.
Gaskets are selected according to the flange grade, while bolts are chosen for stainless steel flanges
Select the gasket based on the material properties, pressure, and flange sealing surfaces.
