Regarding the installation of the saddle sliding device

This post was last edited by Langji Tianya on 2011-2-12 at 17:07. I am currently working on a U-tube heat exchanger with a DN1200 diameter. The design pressure is 4.5 MPa for the tube side and 1.0 MPa for the shell side; the operating pressure is 4.0 MPa for the tube side and 0.6 MPa for the shell side. The design temperatures are 480°C for the tube side and 280°C for the shell side, while the operating temperatures are 420/250°C for the tube side and 40/220°C for the shell side. The material used for the shell side is Q345R, and the material used for the tube side is 15CrMoR. The length of the U-tube elements is 4500, with the total length of the equipment being around 6000, and the length of the tube box being approximately 1200. I am now considering whether it’s necessary to install rollers on the supports
Given its length, it is recommended to use a sliding mechanism to facilitate installation
Reply to 2# Person on the Road-2007: The problem now is that the saddle is too small, making it difficult to adjust its position properly
Sliding strips can also be installed on the baffle plates of the tube bundle; the original poster might want to take a look at GB151
