INSPECT COMPONENTS PRIOR TO ASSEMBLY
Hub and seal ring seating surfaces must be clean and free
from foreign matter. Damage to hub seats and seal lips is
not acceptable, and should be rectified before assembly. |
 |
LUBRICATE
Usually seal rings are coated which acts as lubricant during
make-up. If required light oil or MoS2 spray can be used.
Take care that no solid particles are present in the lubricant. |
 |
| |
|
CHECK SEALRING STANDOFF
The sealring should rock slightly against hub face. Stand-off
dimensions given below in inches. |

ASSEMBLE COMPONENTS
Install sealring into the hubs, and assemble clamps around the hubs.
Lubricant applied to the hub/clamp contact area will aid assembly.
The studbolts should be fitted ensuring that spherically faced nuts
locate into spherical seats of the clamps. Lubrication of nut faces
and bolt threads is recommended.
TIGHTEN BOLTS IN UNIFORM MANNER
Bolting should be tightened to keep spacing between clamp halves
approximately equal. Clamp segments should be shocked with suitable
soft faced hammer to aid assembly. Always re-tighten bolts after
shocking to the torque/preload values given below.
ALIGN HUBS
Hubs should be aligned so that seal ring can be installed between
hubs. DO NOT attempt
to correct badly mis-aligned piping by clamping
force alone; piping pulling forces should only be
released when clamp
is fully assembled.

These values are the minimum recommended. For normal piping
fabrication increase values by 1.5.
For severe piping mis-alignment increase values by 2.0 except for thin walled
hubs - contact Vector International for assistance.
