Omega Pipe Insulation

Description

Omega Pipe Insulation are manufacture from Rigid Polyurethane Foam, which is characterized by its chemical synthesis, its closed cell structure. its low density and excellent thermal stability The product ranges to fit for Pipe of '4" to 22 - N.P.B. and from 25mm to 50mm insulation thickness.

Application Feilds

Within the temperature range of- 180°C to + 120°C. Installation of Omega Pipe Insulation

• Indoor or outdoors concealed or exposed uses.
• In commercial and institutional buildings, housing
Complexes, industrial facilities and plants.

Salient Features

Rigid Polyurethane foam is a combination of strength, the most versatile insulation material for building industry.
These strength include:
c) High water -vapour resistance.
cardboard boxes resistant to impact.
d) High dimensional stability.
e) Light weight

Facings

Glass yam reinforced Aluminium foil and Kraft paper is factory applied over the insulation.

Especially recommended for the insulation of cold pipes running through warm and humid spaces. to prevent vapour condensation over the pipes.
Longitudinal and transverse joints are wrapped with self adhesive tape.

Application Fields

The standard length of Omega Pipe Insulation is 1 meter..The product is in two longitudinal sections.

Packing

Omega Pipe Insulation are packed in corrugated cardboard boxes resistant to impact.

Advantage

Excellent Heat deflection temperatures. with a relatively low coefficient of thermal expansion and good thermal insulation property. High surface hardness, high flexural rigidity and high impact strength. Very easy to transport, handle and install. Exhibit good resistance to alkalis, organic and inorganic acids, and excellent resistance to hydrocarbon solvents, oils and greases.

Rot proof. mildew resistant, antiseptic, almost Typical Properties completely without odour and are physiologically suitable for most applications.

Characteristic Parameters of the fire behaviour of Polyurethane

a) Ignitablity:
When exposed to Omega Polyurethane Foam remain stable up to temperature of 190oC to 200oC,longer exposure to elevated temperature may result in melting and decomposition. The flash ignition value of 290oC - 300oC was obtained using the Setchkin apparatus in accordance with ASTM D 1920(53).

b) Contribution to Flame Spread:
The contribution to Flame Spread of rigid Polyurethane foam is considerably reduced if they are provided with non-combustible facings such as Aluminium foil. Composite building materials of this sort attain a favourable fire safety classification such as Dn4102, NEN 338, BS 476 etc.

c) Contribution to Heat Generation:
In addition to the ignition risk and contribution to flame spread, the hazardous nature of combustible material is also characterised by their contribution to the overall Calorific Balance of the fire.

Thermal Conductivity

Economical insulation is one of the main requirements made in the building industry , in technical insulation and in refrigeration etc. The most important condition for this economy is a high insulation capacity. Rigid Polyurethane foam is characterised by its unrivalled insulating effect. The closed cells of the finished foam are filled with the vaporised blowing agent, which has an extremely low thermal conductivity. Static gas largely eliminates the possibility of Omega migration the rigid polyurethane foam, which is enclosed and impervious to diffusion, calculated values of 0.020 W/m°K or lesser. could be established.
