Thermocouple Tubes, Beads & Sheaths


THERMOCOUPLE SHEATHSTHERMOCOUPLE SHEATHS
Hitemp thermocouple sheaths are used as protective covering over sensing elements. So that the elements are protected from the injurious effects of the furnace atmosphere. These thermocouple sheaths are manufactured either by slip casting or by extrution. Vacuum Extruded thermocouple sheaths are dense & highly impervious & give better life compared to conventional slip casted ones.

Thermocouple Sheaths (Length upto 1500 mm)

THERMOCOUPLE BEADS
Hitemp thermo couple beads are used to provide electrical insulation to the couple which is used for sensing the temperature inside the furnace. These are single, twin , Four hole bore . These are generally used in small lengths of 25mm. However longer lengths are sometime preferred in critical applications.

Laboratory Furnace Parts

MUFFLES
Muffles are mainly used in muffle furnaces where heating elements made out of kanthal / Nircrome wires wraped round the muffles generally in the form of coils & inside these muffles objects are kept for heating either for laboratory or industrial purposes. these muffles are made in different Square/ rectangular dimensions . Hitemp Muffels are thin walled for quicker heating. These are rodust in constructions Highly thermal shock resistant.

GROOVED REFRACTORIES
Grooved refractories are mainly used in High temperature muffle furnaces. The heating coils made out of kanthal / Nircrome wire coils in U Shapes are placed in the groove of the refractories. Higher temperature in these furnaces is achieved as objects are heated directly by radiation . Hitemp Grooved refractories are thin walled & light weight for faster heating . By using Hitemp Grooved refractories peak temperature is attained in almost 1/4th the time as compared to conventional grooved refractories available in the market.These are robust in constructions Highly thermal shock resistant.

BUNSEN BURNER CRUCIBLES
Hitemp Bunsen burner crucibles are used to support heating element on the outer side of their conical structure & inside provides sufficient space for keeping small samples or test tubes.

Ceramic Furnace Supports




Ceramic Furnace Supports :


ELEMENT SUPPORTING TUBESELEMENT SUPPORTING TUBES/ ROUND MUFFLES
Hitemp Element supporting tubes are used for supporting coiled shaped heating elements made out of Kanthal / Nicrome wire used in resistance wire furnace. These tubes have high softening temperature & excellent thermal shock resistance. Hitemp has mastered different compositions to meet out typical air quenching requirements also. These tubes are available in standard diameter with length upto 1500mm.

TUBE HOLDING BRICKS/ELEMENT HOLDING BRICKS
Tube holding bricks are used to support the element supporting tubes where as element holding bricks carry the elements directly in their grooves.
COLLAR TUBES/ COLLAR BUSHES
Hitemp Collar Tubes are used for taking out the electrical terminals from the furnace & to help
insulate the structure from the electric current , these tubes are not subjected to the peak furnace temperature yet theses must be strong enough & do not get broken.
GAS PASSING TUBES
Hitemp gas passing tubes are used to carry different gases to maintain atmosphere in the furnace . These are also used to provide stirring in the molten noble metals in addition to the desired inert atmosphere.
MULTI HOLE DISC
Hitemp Multi hole disc are used in the radiant metallic heaters to insulate elements from the metal tubes. These Disc have high mechanical strength as well as high thermal shock resistance.
CUP LOCKS, BOBBINS, WASHERS
These are used for holding the ceramic blankets in place. These products have high mechanical strength as well as high thermal shock resistance
