Note:
1. Pressure: 0.25 - 10.0MPa connection mode: flange (according to gb9112-9131) or welding.
2. The expansion clearance and installation length can be made according to the user's requirements.
Installation precautions:
1. Before installation, loosen the gland bolts, pull the wear-resistant retractor to the installation length (see the table above), and then tighten the bolts diagonally without bias.
2. The expander shall be installed between two fixed supports on the straight section of the pipeline. In order to ensure the normal expansion of the expander and prevent pulling off, guide supports and stops shall be set.
