Setting of the lifting ring screws on the tube sheet?
Thread Content
May I ask where the eye bolt screws on the tube sheet are located? On the tube side? Is it inside the tube box? Still on the side? Set a few suitable values – how do I calculate them?
The suspension screw is located on the tube side of the tube sheet, so that it allows the tube bundle to be removed during maintenance. It must be inside the pipe box; 2 should be installed for sizes below DN400, while 4 are recommended for sizes above DN400.
