Description owens corning fiberglas pipe insulation is molded of heavy density resin bonded inorganic glass fi bers that come in one piece 36 914mm long hinged sections.
Pipe insulation material density.
Grade 3 formulation does not contain any leachable chlorides fluorides or polyvinyl chloride or any halogens.
Thermal conductivity of the insulation material for the temperature range of the pipe can be taken as 0 04 w m k.
For pipe insulation the r value varies not only with the insulation thickness and thermal conductivity k value but also with the pipe outer diameter and the average material temperature.
Upper and lower temperatures within which the material must retain all its properties.
The r value thermal resistance compressive strength moisture etc.

Understand a typical works specification.
The heat loss from steam per meter of pipe length has to be.
In commercial practice two or three layers of fibreglass 450 g m 2 density mat and resin or two layers of 450 g m 2 mat and a finishing layer of 300 g m 2 mat and resin are applied over the insulation material.
Insulation materials and properties mp 3 2 3 1 thermal properties of insulation thermal properties are the primary consideration in choosing insulations.
Pipe insulation fits around hot water pipes and reduces heat loss to save energy and lower energy costs.
