This
type of foams are mainly used in for cold insulation purpose
Slab sheets:
|
These are made to standard size
of 1000 mm X 500 mm, and a special size of 2000mm X 1000mm invarious thickness ranging from 20 mm to 200
mm and density ranging from 34Kg + or - 2Kg/Cu.m to 60 Kg + or -
2Kg/Cu.m. Used for various applications in cold storage. Cold
plants, freezers etc. |
 |
Pipe sections :
To Suit 12mm NB to 750 mm NB Wall
thickness ranging from 25 mm to 100 mm
STD. Length : 1000mm

 |
Specific dimensions can be made to order, Pipe Section can be
supplied in 2 & 3 Layers for thickness above 75mm.
Pipes are made in the form of half round X 1000mm long to suit
various Nominal bores of Pipe lines for insulation purpose.
Most of the manufacturers do not have pipe sections for sizes above 350 mm NB, for the larger
sizes they use to cut slab sheets and paste it on the curved surface of the pipe line. This kind of
insulation will not be properly insulate as the cut pieces would not touch the curve at many places
and joining with bitumen will have gaps at places giving chance of air entering inside.
.
We, manufacture pipe sections to the size of 750 mm dia of various thicknesses and beyond that we
manufacture lag sections from 1 mtr dia to 4 mtr dia.

TIDEL PARK TES TANK
Lag sections are specially
moulded for larger diameter / radius shells tanks etc. to
suit the curvature of the tanks or shell, these sections are
suitably moulded and are layered one upon the other to
increase the thickness of the insulation by staggered
joints. This method is useful in the absence of insitu-pouring/foaming
and to prevent blowholes or unfilled area by insitu foaming
method of insulation. The picture on the left shows the
fixing of lag section and see the finished, Asia’s Largest
TES Tank in TIDEL PARK Chennai. |

Advantages
|
- Lower thickness of sunfoam insulation is enough, compared to other
materials.
- Lower thermal diffusivity of Sunfoam will result in lower rise
in conditioned temperture in covered area.
- Sunfoam can be used for dual temperature systems Applications.
- Sunfoam could be made to custom built, against specific order to
suit any contour, even with overlappling joints
- Sunfoam moulded products come with water resistant skin, thus
need no extra facing.
- Sunfoam is coversant & adaptable to all conditions and
application.
