High Temperature Technical Textiles & Insulation
SILICONE COATED FIBER GLASS FABRICS

Base fibre glass fabrics of different thicknesses are coated / laminated with silicone rubber in various thicknesses. Various colours of silicone are also available of which the most common are Red, Grey, Black and White. Applications of Silicone coated fibre glass fabrics are for furnace curtains, expansion joints bellows, cable protection sleeves etc, etc.

 

ALUMINIUM FOIL / FILMS LAMINATED FABRICS

URJA has mastered the art of laminating Aluminium Films / Foils on various cloths like Fibre Glass, High Silica, Aramid etc. These fabrics are used in various Insulation & Protection applications from Aerospace to Navy and from Refineries to HVAC ductings and from aprons & gloves to protective suits.

 

HIGH SILICA FABRICS

URJA was the first manufacturer of HIGH SILICA FABRICS in India in year 1992. Today, we have range of silica fabrics with silica content from 50% to 98% depending on the applications.

Silica Fabric are most popularly used in 0.6 mm and 1.2 mm thickness.

 

CORRUGATED BELLOWS

Bellows are stitched from high temperature fabrics like SILICONE COATED GLASS CLOTH, ALUMINIUM FOIL GLASS CLOTHG, PTFE COATED FIBER GLASS FABRICS, HIGH SILICONE FABRICS etc.

Bellows are stitched in round, square rectangular shapes, as per requirements. Length is not a constraint.

WELDING BLANKETS
Welding blankets are used to protect human beings, materials and equipments from welding splatters/sparks produced during the process of welding. Blankets are also used to protect surroundings from heat during gas cutting and gas welding.

 

Welding blankets are made from Glass fabrics, High Silica fabrics and Ceramic fabrics.

Glass fabrics with Vermiculite coating are also available. These blankets can also be provided with loops for hanging or with eyelets.

 
CABLE PROTECTION SLEEVES

Cable Protection Sleeves are used to protect cables and hoses from high heat, molten metal splashes, occasional flames in nearby areas. These sleeves are made from Heat Resisting fabrics.

 

The sleeves are also made to suit particular size of cable or hose that are already installed at customer’s site.

The sleeves are generally made from Silicon Rubber Coated Glass Fabrics. For higher temperatures, High Silica Fabrics and Ceramic Fabrics are used.

Cable Protection Sleeves can be supplied with Velcro, Steel Buttons or can be Stitched at site so that they can be fitted on cables which are already connected in the system. Such methods of installation bring extra convenience.

VALVES JACKETS – REMOVABLE AND RE-USABLE

At many areas in Industry, valves are insulated by using insulating wool and cladding the same with aluminium sheet. During maintenance, this has to be dismantled which is time & material consuming. To avoid this, Urja has introduced Removable and Re-usable Valve Jackets.

 

Valve Jackets are made by inserting Insulating material (generally wool) between two layers of fabric and stitching the whole unit with high temperature threads. Generally strings are provided for easy fitting and removal. Thickness of insulation will depend on the surface temperature of the valve.

It is always convenient to use re-usable Valve jackets because of following reasons:-
They are easy to install; They are easy to re-use & re-fit; refitting saves Cost/TIME & they work in all weather conditions.

INSULATION PADS & GAS TURBINE INSULATION
The surface of some Gas Turbines, are insulated by using pillows made from Heat Resisting Fabrics and insulating wool.

 

Fabric used is generally Glass fabric with SS wire woven into it. Insulation used is generally Ceramic wool blankets of heavy density.

Pillows/pads are made from above material and are stitched with Heat resisting threads to fit the contours of Gas turbine. These pillows are fitted like a jig-saw puzzle to take the shape of turbine surface. Each pillow/pad is placed next to each other by using lancers through which SS wire is passed for secured fastening.

Above insulation is removable and reusable in nature thus saving TIME / COST.
