High-Precision Tubesheets for Heat Exchangers & Pressure Vessels
Product Description
The Critical Component for a Leak-Proof Seal
The tubesheet is the heart of a shell and tube heat exchanger. It provides the mechanical support for the hundreds or thousands of tubes and, more importantly, creates the seal that separates the shell-side and tube-side fluids. A single leaking joint due to poor material quality or inaccurate machining can lead to process contamination, equipment failure, and costly unplanned shutdowns.
Yile Machinery is a specialist manufacturer of custom-machined tubesheets, baffle plates, and support plates, engineered to the highest standards of precision and reliability.
Our Manufacturing Process for Flawless Tubesheets
We understand that there is no room for error in a tubesheet. Our manufacturing process is tightly controlled to guarantee a perfect fit and a long service life.
1. Certified Material Sourcing & Verification
It all starts with the right material. We procure our raw materials (forged billets or heavy plates) from reputable mills, complete with full Material Test Reports (MTRs) . We work with a wide range of materials compliant with international standards:
Carbon Steel (e.g., SA-516 Gr.70)
Stainless Steel (304/304L, 316/316L)
Duplex & Super Duplex Stainless Steel
Nickel Alloys (Inconel, Monel)
2. Precision CNC Drilling & Machining
The accuracy of the tube holes is paramount. We utilize advanced CNC gun drilling and multi-spindle drilling centers to machine the tube hole pattern.
Extreme Accuracy: We achieve tight pitch tolerances, ensuring perfect alignment for automated tube installation.
Superior Hole Finish: Our process produces a high-quality hole surface finish, which is critical for achieving a secure and leak-proof seal during tube expansion (rolling) or strength welding.
Complex Features: We can machine complex features, including double tubesheets and pass partition grooves for multi-pass exchanger designs.
3. Final Inspection & Quality Assurance
Every tubesheet undergoes a rigorous final inspection before shipment. Using Coordinate Measuring Machines (CMM) and other precision instruments, we verify:
Hole diameter, position, and concentricity.
Gasket surface flatness and finish.
Overall dimensional accuracy against your drawing.
We provide a full dimensional inspection report and 100% material traceability with every part.
