Pipe Insulation Material Density

The r value thermal resistance compressive strength moisture etc.

Pipe insulation material density. Insulation body material closed cell foam 10 closed cell glass 37 epdm 85 fiberglass 112 halogen free nbr 13 melamine foam 80 mineral wool 34 nbr pvc. An alternative method for the use. All three grades are flexible and resilient closed cell expanded foam insulation. Grade 3 formulation does not contain any leachable chlorides fluorides or polyvinyl chloride or any halogens.

Will vary by density and. The maximum water vapor permeability is 0 10 perm inch and the maximum thermal conductivity at 75 f temperature is 0 28 btu in h ft 2 f for grades 1 and 3 and grade 2 is 0 30 btu in h ft 2 f. This article provides a table of insulation values and properties for various insulation materials useful in procedures to measure or calculate heat loss in a building defines thermal terms like btu and calorie provides measures of heat transmission in materials building insulation design data and heat loss in a building. For this reason it is more common to use the thermal conductivity value when comparing the effectiveness of pipe insulation and r values of pipe.

Refer to the following glossary for definitions. Xps extruded polystyrene is a closed cell rigid foam insulation for low temperature 168 f pipe insulation systems for chilled water and refrigeration. Xps is manufactured by dow chemical blue styrofoam and owens corning pink foamular. The pipe size is 8 and the maximum allowable temperature of outer wall of insulation is 50 0 c.

Understand a typical works specification. Insulation r values of various materials. Identify the hazards associated with insulation materials. Calculate insulation thickness minimum value required for a pipe carrying steam at 180 0 c.

Owens corning is a worldwide leader in building material systems insulation and composite solutions delivering a. The polyester resins are applied with a roller until a lining about 4 5 mm thick is obtained. 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. Thermal conductivity of the insulation material for the temperature range of the pipe can be taken as 0 04 w m k.

Fiberglas pipe insulation. 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. Insulation materials and properties mp 3 2 3 1 thermal properties of insulation thermal properties are the primary consideration in choosing insulations. Upper and lower temperatures within which the material must retain all its properties.

The heat loss from steam per meter of pipe length has to be.
