Aerogel in Kolkata — Aerogel Insulation for Steel, Power, Haldia Petrochem and Buildings
Buying aerogel in Kolkata? Eastern India’s heavy industry — steel, power, petrochemicals and engineering — runs some of the hottest equipment in the country, and much of it sits in humid, riverside conditions. Wedge Industries Limited supplies WedGel silica aerogel blanket with thermal conductivity of 0.018 W/m·K at 25°C, grades from cryogenic to 650°C and thickness from 3 mm to 50 mm — about 10 mm of aerogel does the work of 40–50 mm of mineral wool.

Aerogel in Kolkata: where it is used
Aerogel in Kolkata serves a wide industrial hinterland. At Haldia, refinery and petrochemical units use it on steam and process lines and on flanges and valves that are hard to insulate with rigid sections. In the Durgapur–Asansol steel and power belt, WedGel 650°C grades are used as backing insulation behind refractory, on exhaust ducts and on turbine casings where space is tight.
Closer to the city, foundries and engineering works in Howrah, Kalyani and Budge Budge use aerogel on furnaces, ovens and hot-oil lines, while hospitals, hotels and commercial towers use it for services in crowded plant rooms.

Which aerogel grade should I use?
WedGel WAG400 for service from −50 to +400°C, WedGel WAG650 up to +650°C, WedGel ECO as the budget 650°C grade, and the WedGel 200 / 125 series for chilled and cryogenic lines. Send the operating temperature and Wedge Industries Limited specifies the grade and thickness.
How much thinner is aerogel than mineral wool?
In the same duty, roughly 10 mm of aerogel does the work of 40–50 mm of conventional insulation such as mineral wool or calcium silicate, which is why it is chosen for congested pipe racks, equipment guards and space-limited retrofits.
Can aerogel be used behind refractory in steel plants near Kolkata?
Yes. WedGel WAG650 blanket and the RP1000 rigid aerogel panel are used as backing insulation behind refractory linings and on furnace casings, reducing shell temperature in less thickness than conventional backing materials. Share the hot-face temperature and lining design for a recommendation.
Do you supply aerogel for Haldia refinery shutdowns?
Yes. For turnaround work the usual products are WedGel WAG400 and WAG650 blanket, removable aerogel jackets and WJ-Jelly or WJ-Paste for flanges and valves. Material is dispatched ahead of the shutdown window.
