Tube bundle heat exchanger - has horizontal assembly of parallel tubes held by plates and tie rods

摘要

The exchanger has parallel tubes (7) held in an outer covering (12). The tube ends are fixed on thick plates (6) and divided into sections by intermediate perforated plates (1). These are discs with a cylindrical rim of smaller dia. than the covering interior. The discs are welded on (13). Longitudinal tie rods pass through the plates to hold via stops fixed on them. The stops are rings welded onto the rods, positioned below plates (1). The stops can be stay tubes threaded over the rods. The plates are about 10mm thick.
