Installation Guide


Ensure both pipeline flanges are aligned before installation.

Insert bolts diagonally and tighten gradually to prevent stress concentration.

Do not exceed the allowed axial, lateral, and angular movement.

Avoid direct sunlight and sharp objects during storage and installation.

For higher pressure systems, consider using limit rods to prevent overextension.
