How to do the budget of pipeline insulation project?

First of all, according to the calculation rules of engineering quantity, the cubic number of insulation layer and the flat number of protective layer are calculated according to the engineering quantity of pipeline, and it depends on whether the design requires external painting of fire retardant paint.

Then check the local quota, and check the cost of insulation layer, protective layer and fire retardant coating (if any) in turn, so that the man-hour cost per meter of pipeline insulation can be calculated. Of course, the labor cost in the quota is not quite consistent with the actual labor cost. If it is outsourced, the pure labor cost is about 60-70% of the labor cost in the quota, and it must be in accordance with local standards.

Material cost:

The insulation layer is probably centrifugal glass wool, rubber and plastic, rock wool, whether it is a shell or not;

Glass fiber cloth and paper are more used for protective layer; Do we have to go to the local area to inquire about the price? According to thickness, quality, etc. There are still considerable differences from place to place.
