A stainless-steel tube bundle is the heat-transfer core of a shell-and-tube heat exchanger. Hengke supplies drawing-based assemblies for coolant distribution units, facility-water interfaces and industrial thermal-management systems.
Hengke Casting operates under ISO 9001 and IATF 16949 quality systems and supports applicable BV, DNV and PED documentation requirements for customer projects.
Tube diameter, wall thickness, length, pitch, baffle layout and heat-transfer area are determined from the required duty and allowable pressure drop. Tube-side and shell-side operating conditions must be specified separately. Tube sheets, headers, supports and connections are manufactured to the approved drawings.
The tube-to-tube-sheet joint, weld procedure, cleanliness level and corrosion-control treatment are agreed before production. Stainless castings can be used for custom headers or manifolds, but the tube bundle itself is a fabricated heat-exchanger assembly—not an investment casting. Casting tolerance VDG P690 D2 therefore does not apply to the completed tube bundle.
Please provide heat load, fluid composition, temperatures, flow rates, pressure, allowable pressure drop, envelope dimensions, connection standards, inspection requirements and annual quantity.
