Marking issues for stainless steel flanges
Thread Content
Can steel stamp markings be applied to stainless steel flanges?
Flanges have steel stamps stamped on their sides. All the flanges I bought are like this.
If you purchase flanges produced by standard manufacturers, there will be a steel stamp on the side of the flange, indicating mainly the material, specifications, and pressure rating.
Reply to 3# Junior Clerk: I think there’s a rule stating that large stamps cannot be used on stainless steel, right? What’s going on here?
Reply to 4# wswshishui: This refers to the practice of marking areas near the welds of the main pressure-bearing components during the manufacturing of pressure vessels. This is generally not allowed in stainless steel vessels in order to prevent corrosion.
Reply to 5# Wen Bing: Should transplantation be marked? Is stainless steel also not allowed in pressure vessels?
The flanges produced by our company are generally stamped with a steel mark.
Stainless steel flanges can have stamps applied to their side surfaces.
Markings can be made on the outer circumference of the flange
Strictly speaking, it is not allowed to use stamp printers; there are specialized printers with dedicated ink.
Stainless steel printing is generally done on the cylinder body, at the weaker areas of the welds; flanges are acceptable, as long as it does not affect sealing on the sides.
