A tube bundle is a core component of a shell-and-tube heat exchanger, consisting of multiple parallel tubes held by tube sheets and supported by baffles. It facilitates heat transfer between two fluids.
Materials on file include stainless steel, carbon steel, copper alloys, and titanium. Specific grades, such as ASTM A312 304–316L, are listed as reference; confirm with the manufacturer.
Key parameters include number of tubes, tube length, outer diameter, wall thickness, heat transfer area, design pressure, design temperature, tube pitch, layout angle, tube-to-tubesheet joint type, and weight. These are reference ranges.
Check the design against your process requirements, confirm compliance with applicable standards (e.g., ISO 4200, GB/T 151), and obtain material certifications and dimensional inspection reports from the supplier.
