Benefits of Commercial and Industrial Insulation


Conserves Energy by Reducing Heat Loss or Gain
Properly designed and installed insulation systems immediately reduce the need for energy, a costly ingredient of every product made.

Controls Surface Temperatures for Personnel Protection and Comfort
Insulation reduces the surface temperature of piping or equipment to a safer level, resulting in increased worker safety and the avoidance of worker downtime due to injury.

Facilitates Process Temperature Control
By reducing heat loss or gain, insulation can help maintain the process temperature to a pre-determined value. Insulation thickness must be sufficient to limit the heat loss in a dynamic system or limit the temperature drop, with time, in a static system.

Prevents Condensation on Cold Surfaces
Specifying sufficient insulation thickness with a good vapor retarder is the most effective means of controlling condensation and limiting corrosion on cold piping, ducts, chillers and roof drains. Sufficient thickness is needed to keep the surface temperature above the dewpoint temperature of the ambient air.

Prevents or Reduces Damage to Equipment From Exposure to Fire or Corrosive Atmospheres
When used in combination with other materials, fiber glass and rock and slag wool insulation help provide fire protection in firestop systems; grease- and air-duct fireproofing; and electrical and communications conduit and cable protection.

Controls Noise
Special or standard insulation materials can be used to encase or enclose a noise generating source, forming a sound barrier between the source and the surrounding area. Insulation installed in walls and ceilings can provide a barrier to the entry of sound from the outside or other rooms. Click here for literature on noise control.

Frost Protection Systems

Heat tracing can be used to protect exposed pipework from freezing. The most common usage is to ensure prevention of freezing of pipework for water services. However the term frost protection more widely referes to maintain pipe contents at temperatures to stoped the contents solidifying.

 

Fiber Glass Pipe Insulation
Fiber glass pipe insulation is a molded, heavy density, one piece insulation made from inorganic glass fibers bonded with a thermosetting resin. It is produced in 3’ lengths with or without a jacket. It is used on mechanical and process piping in power, process and industrial applications, and in commercial and institutional buildings. Most fiber glass pipe insulations can be used on systems from 0º to 1000º F.

Rock Wool Pipe Insulation
Rock wool (or mineral wool) pipe insulations are precision cut pipe coverings composed of high density mineral wool. It can be used in a wide range of applications for hot and cold piping ranging from –120ºF to 1200º F. This product is frequently used in high temperature industrial process power plants, power stations, petrochemical complexes, etc for steam and process pipe work – and for commercial hot/cold water systems. It is produced in two half cylinders and can be supplied either plain or with a FSK type facings. It comes in 3’ lengths in pipe sizes from 1/2" IPS to 20" IPS.
   

Elastomeric Pipe Insulation

HFoamed resins combined with elastomers produce a flexible cellular material. Available in pre-formed shapes and sheets, elastomeric insulations possess good cutting characteristics and low water and vapor permeability. The upper temperature limit is 104.4ºC (220ºF). Elastomeric insulation is cost efficient for low temperature applications with no jacketing necessary. Resiliency is high. Consideration should be made for fire retardancy of the material.
.The easiest and quickest method to insulate already existing pipework is to use elastomeric (nitrile rubber) insulation material. This highly flexible non-fibrous insulation material makes safe application easy, especially in areas of limited available working space.

Elastomeric insulation’s biggest asset is its excellent thermal efficiency

Foamed Plastic
Insulation produced from foaming plastic resins create predominately closed-cellular rigid materials. "K" values decline after initial use as the gas trapped within the cellular structure is eventually replaced by air. Check manufacturers' data. Foamed plastics are light weight with excellent moisture resistance and cutting characteristics. The chemical content varies with each manufacturer. Available in pre-formed shapes and boards, foamed plastics are generally used in the low and lower intermediate service temperature range -182.8ºC to 148.9ºC (-297ºF to 300ºF). Consideration should be made for fire retardancy of the material.

The temperature range within which the term "thermal insulation" will apply, is from -73.3ºC (-100ºF) to 815.6ºC (1500ºF). All applications below -73.3ºC (-100ºF) are termed "cryogenic," and those above 815.6ºC (1500ºF) are termed "refractory."

Thermal insulation is further divided into three general application temperature ranges as follows:

A. Low Temperature Thermal Insulation

1. 15.6ºC through 0ºC (60ºF through 32ºF) -- i.e. Cold or chilled water.
2. -0.6ºC through -39.4ºC (31ºF through -39ºF) -- i.e. Refrigeration or glycol.
3. -40.0ºC through -73.3ºC (-40ºF through -100ºF) -- i. e. Refrigeration or brine.
4. -73.9ºC through -267.8ºC (-101ºF through -450ºF) -- i. e. cryogenic.

B. Intermediate Temperature Thermal Insulation

1. 16.1ºC through 99.4ºC (61ºF through 211ºF) -- i.e. Hot water and steam condensate.
2. 100.0ºC through 315.6ºC (212ºF through 600ºF) -- i.e. Steam, high temperature hot water.

C. High Temperature Thermal Insulation

1. 316.1ºC through 815.6ºC (601ºF through 1500ºF) -- i.e. Turbines, breechings, stacks, exhausts, incinerators, boilers.
