What is Tubesheet Flange

A Tubesheet Flange is a thick circular plate or forged flange component with multiple precision-drilled tube holes. It is mainly used to support, locate, and seal tubes in shell-and-tube heat exchangers.

Unlike standard pipe flanges, tubesheet flanges require accurate tube hole layout, strict flatness control, precise sealing surface machining, and reliable material performance. The tube holes are usually arranged according to triangular pitch, square pitch, or customized tube layout.

Tubesheet flanges can be supplied as forged tubesheets, clad tubesheets, drilled tubesheets, or integrated flange-type tubesheets according to equipment design.

Tubesheet Flange Materials & Grades

Tubesheet Flange Dimensions

Tubesheet Flange Dimension Drawing

Tubesheet flanges are usually manufactured according to customer drawings because tube hole layout, thickness, sealing face, groove design, and material selection depend on heat exchanger structure, working pressure, temperature, and medium.

Advantages of Tubesheet Flange

Accurate Tube Hole Drilling

CNC drilling and precision machining ensure accurate tube hole diameter, pitch, and layout.

Strong Structural Support

Thick forged or machined construction provides stable support for tube bundles and pressure vessel connections.

Reliable Sealing Performance

Precision sealing face machining helps reduce leakage risk in heat exchanger and pressure vessel systems.

Custom Tube Layout

Triangular pitch, square pitch, rotated square pitch, and special tube patterns can be produced according to drawings.

Cladding and Overlay Options

Stainless steel or nickel alloy cladding improves corrosion resistance while controlling material cost.

Suitable for Complex Equipment

Tubesheet flanges are suitable for heat exchangers, condensers, boilers, evaporators, and chemical process equipment.

Applications

Shell and Tube Heat Exchangers

Used to fix and support heat exchange tubes in shell-and-tube heat exchanger systems.

Condensers
