Tees 2. lin. feet of same size
and thickness
Branch
Fittings 2. lin. feet of same size and thickness
Reducers,
Caps and Termination Points 1.5 lin. feet of same size
and thickness
*Hangers (hot) 1 lin. feet of
same size and thickness
*Including shoe supports and brackets. Excludes
guides and anchors.
Hangers (cryogenic/anti-condensation)
2. lin. feet of same size and thickness
Removable Covers multiply fitting
factors by 2.5, or a price per cover established by tender.
Screwed
/ FRP Fittings:
Specified flexible insulation, multiply all factors
by 2. Specified preformed or rigid insulation – 3 linear
feet per fitting.
Vitaulic Fittings:
These fittings require special consideration because
of size and complexity. Therefore the conversion table factors
are to be multiplied as follows:
| 45 Elbows
|
Multiply factors
3 times |
|
| 90 Elbows
|
Multiply factors 3 times |
Tees, Fittings:
| 1/2"
to 5" |
Multiply factors
3 times
|
|
| 6" to 12" |
Multiply factors 5 times
|
|
| 14" and over |
Multiply factors 7 times
|
Penetrations:
Items which interfere with the insulation system,
e.g., conduits, handrails, ancillary hangers, uninsulated pipe
or tubing, etc.
Each cut out 2. lin. feet of same size and thickness
When penetrations occur at fittings:
Each cut out 3. lin. feet of same size and thickness
Obstructions
Where insulation thickness has to be shaved or
cut for walls, sleeves, equipment or other interferences:
Multiply the length of interference by factor
of 2

If labour component has not been identified apply
only 50% of the above to the unit prices. These percentages are
to compensate for loss of productivity, however safe working conditions
shall take precedent.
