Company Information
PUF / PIR SLABS & PIPE SECTIONS
PUF materials are suitable for temperature range between -200°C to +110°C. PIR Slabs & Pipe Sections are suitable for use between -200°C to +145°C. It has low thermal conductivity value of maximum 0.021 w/mk at 10°C. It is not easily ignitable and has negligible water permeability. It is suitable for cold / chilled pipelines, building roof & wall insulation, equipment insulation and horton sphere insulation.
PIR is suitable for LNG pipe insulation.CFC Free
PUF / PIR is the only CFC Free product, designed within the guidelines of the Montreal Protocol, 1987, for the protection of the Ozone layer.Better Extreme temperature performance
Unlike most thermoplastics, PUF / PIR has low smoke emission and will not melt or drip in a fire,
Being rigid Polyisocyanurate foam, it also has a higher hot surface performance of 150°C compared with only 110°C of normal Polyurethane Foam. This makes it ideal for use directly over steam or electrical tracing.
Its fire classification meets even the stringent requirements of the British Board of Trade for shipboard insulation as per BS 5608, the Indian Navy, and those of the US Bureau of Mines.Better Cost-effectiveness
With PUF / PIR, insulation thickness can be reduced by 50% compared with cork, 44 compared with expanded polystyrene or fiberglass. It exposes lower surface area, reducing area or expensive vapour barrier and outer cladding per running meter of piping.
So insulation parameters can be upgraded without increasing pipe rack spacing.
Ease of application
Resistant to almost all solvents, PUF / PIR is compatible with cold applied adhesives, sealants and vapour-barrier mastics.
PUF / PIR is available in boards, pipe sections, radiused and beveled lags, with or without factory laminated facings.
Cast-Insitu Applicationn
Material Applied at site & suitable for large dia pipelines, underground pipelines & storage tanks.

POLYURETHANE PIPE SUPPORTS
A heavy duty easy to install prefabricated pipe support system of truly revolutionary proportions. Pipe Supports are made from specially formulated chemical systems that results inn high density rigid polyurethane foam. The very nature of the material immediately yields several advantagess:
PROPERTY
ADVANTAGES
Wide Density Rage Possible
Higher densities enable higher loads without increase in surface area.
Pre-Engineered at our factory
No sawing and shaping at site.
The support precisely matches pipe’s OD.
Installation time dramatically reduces.Material has a closed cell structure
Does not permit water penetration.
No wet rot.
No dry rot.Excellent ‘k’ value
Provides vastly superior insulation as compared to timber and other materials.
No condensation at support point. So no drips, puddles or energy wasted.Good fire resistance
Improved safety at site.
Improved durability.Closed Dimensional tolerances.
Pipe Support thickness precisely matches insulation thickness, resulting in neat finish at support location.
Supplied in assembled condition, completed with all metal attachments.
Improved speed of installations.
Joint-free in the load bearing area, even for larger diameters of pipe.Special Sizes, Shapes and Finishes
On request On- Standard sizes & shapes can be manufactures to suit specification. Supports can be supplied with a factory – applied coat of fire-resistive mastic, which also serve as a vapour barrier, on the exposed surface,
