Tube Sheets and Custom Flanges

Henan Beibang Steel Co., Ltd. specializes in the production of tube sheets.
Tube Sheet: The "Skeleton" and "Sealing Wall" of Heat Exchange Equipment
The tube sheet is a crucial component in shell and tube heat exchangers. It not only precisely fixes hundreds or even thousands of heat exchange tubes, but also strictly isolates the media in the tube side and shell side.
Our professional capabilities are reflected in:
Wide range of material selection: We can process various materials such as carbon steel (Q235R, Q345R), stainless steel (304, 304L, 316, 316L), composite plates (stainless steel composite, titanium composite, copper composite), duplex steel, Hastelloy, etc., to meet various corrosion conditions.
Ultra-high precision hole processing: This is a reflection of our core competitiveness. We use advanced deep hole drills and CNC vertical drilling machines to ensure:
Precise hole position: The hole spacing error is controlled within ±0.05mm to ensure smooth insertion of the heat exchange tubes.
Consistent hole diameter: The hole wall has high smoothness, laying a solid foundation for subsequent expansion or welding.
Uniform hole bridge: Strictly ensure the minimum wall thickness between holes to meet high-pressure design requirements.
Advanced tube hole structure: We can process smooth holes, slotted holes (for strength expansion), and accurately control the groove depth and groove width to ensure the reliability of the expansion joint seal.
Perfect sealing surface treatment: We can process sealing grooves (such as O-ring grooves) according to requirements, and perform polishing or spraying on the sealing surface.
