Definition Of Overlay Flange:
Flange overlay is used to connect different – material pipeline,for example,if we want to connect carbon steel pipe to 304 steel pipe,we could use A105 flange,and weld SS304 overlay to flange face.Pls check below drawing to get a better understanding.
The only difference from regular flange is to weld overlay to flange face.
The overlay material: SS304,SS316,API line material etc.
