Product details

Tube Sheet Flange is an integrated tube sheet and flange forged pressure component, widely used in shell and tube heat exchangers, condensers, boilers, reactors, and other pressure vessel equipment.

Unlike conventional piping flanges, the Tube Sheet Flange combines two essential functions in one forged structure:

The outer flange section provides a bolted sealing connection for equipment opening, maintenance access, and external piping connection.

The tube sheet section is precisely machined with a large number of tube holes for fixing heat transfer tubes, separating the tube-side and shell-side fluids.

It is a critical pressure-bearing component for special equipment and follows a completely different design philosophy from standard pipeline flanges.

Product Specifications

Note: The flange inner diameter (B) is determined by the wall thickness of the steel pipe and shall be specified by the user at the time of ordering.（Unit: mm）
