摘要： A shell-and-tube equipment (10) comprises a shell (12) that surrounds a tube bundle (14), wherein the tube bundle (14) comprises a plurality of tubes (16). At least one end of each tube (16) is joined to an inlet tube-sheet (18) provided with respective tube-sheet bores (20) for inletting a fluid (22) in the shell-and-tube equipment (10). The inlet tube-sheet (18) is provided with a first side (24), which receives the fluid (22), and with a second side (26), which is opposite to the first side (24) and from which the fluid (22) is delivered into the tubes (16). The inlet tube-sheet (18) is connected to each tube (16) of the tube bundle (14), on its second side (26), by means of a butt-weld joint (28) made from inside a respective tube-sheet bore (20) of the inlet tube-sheet (18) in such a way that each tube (16) does not extend inside the respective tube-sheet bore (20). The inlet tube-sheet (18) is provided, on at least part of its tube-sheet bores (20), with respective tubular protection devices (32) for protecting the tube-sheet bores (20) from high local turbulence and erosion due to the fluid (22) flowing into the tube-sheet bores (20). Each tubular protection device (32) is made in the form of a butt, or a piece of tube, that extends from the first side (24) of the inlet tube-sheet (18) at a respective tube-sheet bore (20) in such a way that there is no physical contact between the tubular protection devices (32) and the tubes (16) of the shell-and-tube equipment (10).
