How To Install Expansion Joint Tie Rods?

The installation steps for expansion joint tie rods are as follows:

Inspect the tie rod: Ensure it is free from deformation and the threads are intact.

Pre-install nuts: Tighten one end of the nut first, leaving some adjustment allowance.

Positioning installation: Align both ends of the tie rod with the flange holes and insert the bolts.

Adjusting the limit: Tighten the nuts symmetrically to maintain even force on the tie rod (torque range is typically 50-100 N·m, refer to the manufacturer's data for specific details).

Reason: Tie rods are used to limit excessive displacement of the expansion joint; improper installation can lead to failure. For example, loose tightening in chemical pipelines may cause leaks.
