What is the difference between a tie rod and a spacer tube? Please tell me
The spacing tube is used to determine the position of the baffle, while the tie rod is used to fix the spacing tube in place.
The spacing tube is interrupted by baffle plates and support plates; the tie rod is a single piece, and the spacing tube is fitted over the tie rod to work together in determining the distance between the baffle plates.

Also, depending on the stress, there is tensile stress in the tie rod and compressive stress in the spacers
The outer diameter of the spacing tube must be larger than the diameter of the holes in the baffle plates; these holes determine the distance between the baffle plates. The tie rod is a single rod that runs from one end plate to the last baffle plate at the other end, and the spacing tube is fitted over this tie rod to fix its position.
The tie rod fixes the position of the tube sheet, while the spacing tube determines the position of the baffle
The tie rod is made of round steel, while the spacing tube is made of steel pipe.
The tie rod serves a fixing purpose, while the spacing tube, as the name suggests, is used for positioning – it functions like a simple clamping device in the machinery industry.
