Custom Tube Sheet

Custom tube sheet is also called baffle plate, which is one of the main parts in a shell and tube heat exchanger systems.

Custom tube sheets have different sizes and a series of holes are done to create a place where the tube ends are welded.

Manufacturing raw material including stainless steel, duplex stainless steel, titanium, carbon steel, super nickel alloy, etc.

Whatever size at whatever tight tolerance of custom made tube sheet you demand, SEATHER here is sure to have it!

Custom Tube Sheet Fabrication Techniques

Custom tube sheet design and production is largely automated these days with computer software (like CAD) performing the calculations and the tube sheet drilling done on computer numerical control (CNC) machines.

Tube Sheet Surface: Anti-rust oil, clear lacquer, Black lacquer, Yellow lacquer, hot-dipped Galvanized, electrical galvanized

Technical: Forged, Casting, Machining

Heat Treatment: Normalizing, Annealing, Quenching, Tempering

Material: The tube shapes include round, oval, square, inclined and special ones, with the hole dimension accuracy to 0.01mm, hole wall roughness Ra0.6, and the tube plate’s sealing side roughness Ra0.4. The accuracy of positioning of the holes can reach 0.002mm, and the hole dimension can be any of that above 1mm.

Size: Customized

Custom Tube Sheet: The Ultimate Guide

When you choose to buy custom made tube sheet, there have some important points we need to know before we get started.

So enjoy the read…

What are Custom Tube Sheet?

Custom tube sheet is usually made from a round flat piece of plate, sheet with holes drilled to accept the tubes or pipes in a accurate location and pattern relative to one another.

The tube sheets are used to support and isolate tubes in heat exchangers and boilers or to support filter elements. Tubes are attached to the tube sheet by hydraulic pressure or by roller expansion.

Custom Tube Sheet Applications

Tube plate sheet is widely used in tubular heat exchangers, boilers, pressure vessels, steam turbines, large central air conditioners, condensers, evaporators and other products.

The stainless steel and nickel alloy material makes it not only rigid, but also has great heat conduction performance.

The precision of tube plate processing, especially the tolerance of hole spacing and diameter, perpendicularity, and finish greatly affect the assembly and performance of the equipment listed above.

Typical Hole Patterns of Tube Sheet

The most common types of holes experienced in tube sheet drilling are triangular, rotated triangular, square and rotated square.

See typical pattern types below:

Features of Custom Tube Sheet

  • Corrosion resistant
  • High tensile strength
  • Very durable
  • Temperature resistant
  • Easy formability and fabrication
  • Low-maintenance
  • Attractive appearance
  • Environmentally friendly (recyclable)

What Are Custom Tube Sheet Surface Treatment?

Surface treatment is one of the major part in whole production.

Different surface finish will be used for different custom tube sheet.

With methods including anodizing, passivation, brushing, polishing, blackened, plating, painting, powder coating, heat treatment, surface phosphating, hot dip galvanizing, other surface treatment, etc.

Key Considerations When Buying Custom Tube Sheet

When purchase the custom tube sheet from China manufacturer, you should know the standards, size, materials grades, production process, drawings details, etc.

Below Is One Sample Purchasing Tips For Your Reference

  • Standards: ASTM A240
  • Material Grade: 904L stainless steel
  • Size: As your drawing request
  • Usage: Pressure vessel
  • Production Process: CNC machined
  • Tolerance: -1mm/+1mm
  • Requirement On Properties: As your request
  • Order Quantity, Delivery Time, Shipping Method, Place Of Delivery, Packaging Requirement, etc. should be considered.


Unquestionably, it is quite apparent that custom tube sheet revolves around numerous aspects, some of which we haven’t looked into here. But for now, at least you have the idea of what it takes to buy and install a functional tube sheet that yields efficiency.

We are hopeful that this guide has been significantly helpful to you in many ways. And for that reason, it would be prudent if you also feel free to share it on your social media handles.

You know what, someone might also be looking for this kind of valuable information and you may be of considerable help too.
