Professional Installation Guidelines
Displacement Limits
Never exceed specified displacement limits to maintain joint functionality and system safety.
Bolt Installation
Align bolts with flange holes and tighten gradually using symmetrical pressure distribution to prevent leaks.
Pressure Requirements
For systems exceeding 1.6MPa working pressure, use elastic pressure pads to maintain bolt tension and sealing integrity.
