Functions
Structural Support – Holds tubes in place under high pressure/vibration.
Fluid Separation – Isolates shell-side and tube-side media (e.g., water/steam, chemicals).
Heat Transfer – Maximizes thermal efficiency via optimal tube alignment.
Common Types
Fixed Tubesheet: Permanently welded to the shell (cost-effective, for low thermal expansion).
Floating Tubesheet: Allows expansion (for high-temperature differentials).
Double Tubesheet: Prevents cross-contamination (pharmaceuticals/food industry).
Manufacturing Proces
Material Cutting – Plasma/waterjet cutting of plates.
Drilling – CNC or laser drilling for precision holes.
Welding – Tube-to-tubesheet welding (expanded, seal-welded, or strength-welded).
Application
Quality Control Process Chart
Quality control test
During raw materials，manufacturing，inspection and delivery process，all norms are strictly abided by and process control will be well carried out.All reports will be issued timely to do analysis.
We have devoted a great deal of effort to the process control and management practices in accordance with traceability and consistency of quality will be continually implemented.
In-house control quality inspection：
Spectrometer Detection and Analysis of Chemical Elements
Metallographic Analysis
Mechanical Property Testing(Hardness, Tensile Strength, Yield Strength, Elongation, Reduction of Area, Charpy-Impact)
Ultrasonic, Portable Direct Reading Spectrometer, Macro Erosion Test, Intergranular Corrosion Test, Penetration Test, Magnetic-particle Inspection, Size Inspection, Visual check, We’ll do special tests as per clients'demand and accept the third party inspection actively.
