In shell-and-tube heat exchangers, the tube sheet is the structural core that secures and aligns hundreds of tubes with absolute accuracy. Each plate operates under high temperature, pressure, and corrosive service conditions where even a minor deviation can lead to leakage or failure.

At Schilthorn Precision Engineering Pvt. Ltd., precision is built into every stage of manufacturing. With over 18 years of machining experience, we produce ASME- and TEMA-compliant tube sheets that deliver consistent dimensional stability, corrosion resistance and long-term mechanical integrity across power, process and marine sectors. Every micrometre of accuracy directly translates into exchanger reliability

*Why Tube Sheet Manufacturing Demands Accuracy *

A tube sheet is a thick, perforated plate that anchors and isolates the tube bundle, maintaining a pressure-tight barrier between shell-side and tube-side fluids. Each drilled hole, groove and sealing surface must adhere to strict GD&T and surface-finish requirements to manage thermal expansion and pressure differentials. The life of a heat exchanger depends directly on how precisely this component is machined.

Schilthorn’s facility integrates all key operations under one roof, drilling, grooving, facing and milling performed on HAAS multi-axis VMCs for stable, repeatable accuracy. Every part undergoes CMM-verified inspection and surface-finish measurement to validate conformance with design drawings and tolerance charts. Through CAD/CAM-based programming, calibrated tooling and process traceability, each tube sheet achieves consistent geometry, perfect hole alignment and controlled surface integrity, batch after batch.learn more...
