Tees .62 lin. meters of same size and thickness
Branch
Fittings 0.62 lin. meters of same size and thickness
Reducers,
Caps and Termination Points 0.47 lin. meters of same size and
thickness
*Hangers (hot) 0.31 lin. meters of same size and
thickness
*Including shoe supports and brackets. Excludes
guides and anchors.
Hangers (cryogenic/anti-condensation)
0.31 lin.
meters 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
multiply all
factors
by 3.
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:
| 12.5 mm to 125
mm
|
Multiply factors
3 times
|
|
| 150 mm to 300 mm
|
Multiply factors 5 times
|
|
| 350 mm 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 0.62 lin. meters of same size and thickness
When penetrations
occur at fittings:
Each cut out 0.93 lin. meters 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
HEIGHT ALLOWANCES

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.
