ASME SA516 Gr.70 Carbon Steel Tube Sheet for Shell and Tube Heat Exchanger
ASME SA516 Gr.70 Carbon Steel Tube Sheet for Shell and Tube Heat Exchanger
Product Overview
ASME SA516 Gr.70 tube sheet is manufactured from carbon steel plate specified by ASME SA516 for pressure vessel service. It is widely used in shell and tube heat exchangers, condensers, boilers, and pressure vessel equipment to support tube bundles and separate shell-side and tube-side fluids.
Tube sheets are precision-machined according to engineering drawings, with accurately drilled tube holes, gasket grooves, and sealing surfaces to meet the assembly requirements of heat exchanger systems.
