FIELD: shell-and-tube equipment.
SUBSTANCE: shell-and-tube equipment (10) comprises casing (12), which surrounds multiple tubes (16). At least one end of each tube (16) is connected to inlet tube plate (18) provided with appropriate holes (20) of the tube plate. Inlet tube grid (18) is provided by first side (24) and second side (26). Inlet tube grid (18) is connected to each tube (16) of tube bundle (14) on its second side (26) so that each tube (16) does not pass inside appropriate hole (20) of tube plate. Inlet tube grid (18) is provided at least on part of its holes (20) of tube grid by corresponding tubular protective devices (32). Each tubular protective device (32) is made in the form of a protrusion or part of the tube, which passes from first side (24) of the inlet tube grid (18) on corresponding hole (20) of the tube plate.
EFFECT: shell-and-tube equipment is proposed.
