The tube sheet is the core pressure component of shell-and-tube heat exchangers; hole accuracy directly determines the sealing reliability of expanded and welded tube joints.

Process Highlights

• Integral forged blanks with dense microstructure;
• Precision CNC drilling with controllable hole tolerance;
• 100% inspection of hole diameter and pitch per drawings;
• 100% visual inspection after welding with PT / UT NDT.

Tiancheng tube sheets cover OD φ200 ~ φ3000 mm and thickness 30 ~ 300 mm in carbon steel, alloy steel, stainless steel, titanium and nickel-based alloys.
