2.1. Amount of works on isolation of pipelines materials,
the considered norms, except for isolation
limy and silicic products, asbestoperlitovy isolation
by dusting method, is defined by pipeline length, including
fitting. Fittings and flange connections in pipeline length not
join.
Norms and quotations on isolation of pipelines with a diameter up to 820 mm
are calculated on 10 m of pipelines.
Amount of works on isolation of fittings and flange connections
it is considered separately. Norms and quotations are made on 10 pieces of fittings
and flange connections.
2.2. Amount of works on isolation by the limy and silicic
products, by method of a dusting follows asboperlitovy isolation
to estimate on isolation design volume "in business" according to the project,
without plaster coat thickness.
2.3. The volume of isolation of separate places at the control and measuring
devices and fittings, and also near any hatches, unions,
openings on the equipment it is considered by norms and thus length of the isolated
pipelines it is measured without deduction of the specified places.
2.4. Amount of works on isolation of cold surfaces construction
designs is defined by multiplication of the area of the isolated surface
on isolation thickness according to the project. The volume of fire-prevention belts in
the volume of isolation doesn't join as their device is provided
separately (tab. 26-29, 26-32).
2.5. Amount of works on isolation the bezbalochnykh of overlappings from below
it is necessary to estimate in slabby heaters separately for overlappings and
for columns, thus isolation of capitals has to be considered in volume
isolation of overlappings.
