Extra large flanges are to be completed by a segmented production process. Then splicing to the construction site. Different standard large carbon steel flanges for large carbon steel flanges refer to flanges that exceed the dimensions specified by the relevant national authorities. Large flanges refer to flanges of sizes above DN2000.
The production of such flanges is to be produced by the construction party. General flange standard system
