Large Fitting Needs Temporary Internal Bracing During Handling
Preserve approved transport or temporary bracing until the fitting is supported and ready for installation. Large transitions, plenums, and fittings can rack or collapse when moved without enough stiffness.
This large transition has internal shipping braces and the open end racks when moved. Do they stay until it is supported in place?
Watch out
Do not remove internal bracing just because it appears temporary, and do not add unapproved bracing that damages liner, coating, or internal components.
Check
Check shop marks and instructions before removing any brace, angle, spreader, or blocking.
Look for wide unsupported panels, open ends, and connector faces that can rack.
Move and support the fitting at strong points without crushing panels or reinforcement.
Remove temporary bracing only when the fitting is stable and the installation sequence requires it.
