Thermal Insulation

A provision made to retard heat flow from a hotsurface to a cold environment and from cold surface

to a warm environment.

This simple device in Industry has acquiredenormous importance in recent times for what it can

do for us if we were to give a very little extraattention

SUSTAINABILITY

Thermal transmission, or the transfer of heat

from a warmer body to a colder body may in

principal take place in the following ways:

1) Conduction - Transfer of heat through

solid/liquid material.

2) Convection - The moving of heat through

moving fluid or gas.

3) Radiation - Transfer of heat by means of

electromagnetic waves.

7/30/2019 04 Lloyd

7/107

Heat Conduction

Conduction is heat transfer by means of molecular agitation within a materialwithout any motion of the material as a whole. The higher speed particles will

collide with the slower ones with a net transfer of energy to the slower ones.

For heat transfer between two plane surfaces, the rate of conduction heat

transfer is:

Q = heat transferred in time =

K= thermal conductivity of the barrier

A = area

T= temperature

d = thickness of barrier

The exact rate of Heat Loss is very complicated to calculate on

theoretical ground alone, since it shall be affected by -

Metal Cladding- some important issues.. As can be easily appreciated, all metal cladding materials need

careful selection from external corrosion point of view as a firstconsideration.

However, another important aspect concerns corrosion fromwithin- contributed by condensation of vapours from theinsulation system on the inner surface.

Since most insulants are faintly alkaline, such condensed waterattacks the metal particularly Aluminium and causes it to pit

and fail as a barrier. All metal cladding, as a rule need protection on the inner

surface- like a factory laminated Poly Surlyn treatment.

Vapour Barrier in cold service

Installed on the high vapour pressure side-I.e., thewarmer side of the insulation systemprior tocladding), Vapour Barrier (or Vapour retarder as it isreferred sometimes) is designed to arrest entry ofmoist vapour into the insulation, causing it to soak

and possibly to freezing. Insulating Material, when wet can be 30 times more

conductive and would no longer be an insulant!

Freezing of water is always accompanied by

volumetric expansion resulting in rupture. In cold insulation system, therefore, the

soundness of the VB virtually determines howgood the insulation system is.

METHODS OF APPLICATION

All insulation materials applied, shall be in close contact

with the surface to which they are applied, with the

ends butted to one another.

b) Proper density and thickness of material to be applied.

MULTI LAYER INSULATION

All joints to be staggered and each layer shall be

separately secured.

All fittings shall be insulated separately and should betaken out easily without disturbing the main

insulation.

For pipelines operating above 5000C combination ofCeramic Fibre & Rockwool can be used for reducing

heat loss, taking advantage of lower K-value of Ceramic

Fibre at higher temperature.

APPLICATION SYSTEM

All pipes (upto 14) should preferably be insulated withpipe section. The pipe sections shall be held with pins

or wires at a spacing of not more than 450mm.

When multiple layer to be used, the 2nd layer should bewith mattress and tightly held with wires.

For vertical and near vertical piping metal rings to

be used over pipes to stop downward displacement of

insulation.

Lloyd Standing Seam 2000 Panels The panels are fixed by a concealed metal clips fastening

system held between flanges of panels which are mechanicallyseamed together to result in a robust and water-tight seam.

A seaming tool forms the adjacent panels into a vertical seam

that includes the clip. Clips are fastened to Insulation Support Rings with vertical

spacing of 2000 mm and horizontal spacing of 450 mm

Clips have provision to accommodate thermal expansion andcontraction

The clip cross section is chosen as per wind load requirements.

THERMASEAM PRE-INSULATED PANEL

THERMASEAM Pre-insulated Panels are accepted &established superior product for Thermal Insulation andcondensate prevention on tanks.

On installation, they makean unique tank insulationsystem due to the design,robustness & ease of

application.

THERMASEAM Pre-insulated has a galvanized, galvalume (coloursoptional) or aluminium outer sheet lined with Thermal Insulation(Rockwool / Polyurethane Foam / Polyisocyanurate Foam) on innerside.

These panels areinstalled vertically tothe full height of tank side walls andare also utilized onthe tank roof.
