In the complex systems of heat exchangers, boilers, and filtration systems, tube sheets are essential components that determine efficiency, safety, and service life. Often described as the backbone of these systems, tube sheets are precision-engineered sheets, typically round in shape, drilled with precisely aligned holes that support, separate, and seal the tubes. As a leading manufacturer in China, SN Valve specializes in advanced engineering and produces high-quality tube sheets that meet the most stringent industry standards.
A tube sheet is a critical structural element that acts as a bulkhead, securing hundreds or even thousands of tubes within a shell. Its main functions include:
Support: It maintains precise alignment and spacing between tubes, preventing vibration and sagging under operational stresses.
Isolation: It creates a barrier between two different fluid streams—one flowing in the tubes, the other in the shell—ensuring they do not mix.
Seal: The tubes are connected to the tube sheet holes by mechanical expansion or welding, creating a tight seal that can withstand high pressure and temperature differentials. Corrosion Resistance: The tubesheets can be plated with a corrosion-resistant alloy, providing superior protection without the expense of purchasing solid alloy plate, resulting in significant cost savings and improved performance.
The design and manufacturing precision of the tubesheets directly impacts the thermal efficiency, pressure drop, and overall reliability of the entire unit.
For applications where absolute prevention of fluid cross-contamination is crucial, such as pharmaceutical, food and beverage, or chemical processing, the double tubesheet design is highly recommended.
How It Works: This design features two separate tubesheets at each end of the tube bundle, with a small gap between them.
The outer tubesheet resides outside the shell pressure boundary.
The inner tubesheet is the primary structural component within the shell.
Leak Detection: The space between the two tubesheets is vented to the atmosphere. If a leak occurs on the shell or tube side, it is vented directly to the outside, providing immediate visual detection and preventing mixing of the two process fluids.
Safety: This design virtually eliminates the risk of hazardous fluid mixing, ensuring product purity and operational safety.
