Sapphire Thermocouple Tubes/Protection Tubes

Saint Gobain Silicon Carbide Tubes, Ndurance Tubes, Silicon Carbide Thermocouple Tubes, Silicon Carbide Tubes

Innovative Growth Enterprises are the largest suppliers of "Silicon Carbide Ndurance Thermocouple Tubes" in the country. We represent Saint Gobain High Performance Materials , the inventor of Silicon Carbide in the world.

Why Ndurance Silicon Carbide Tubes:

Precise and reliable temperature measurement is a critical requirement in any casting process. For example, the automotive industry increasingly requires suppliers to limit temperature deviations to no more than five degrees Celsius from the specified values. Thermocouples must therefore be protected by a material with a high thermal conductivity, high strength and good thermal shock resistance. Saint Gobain Ndurance Silicon Carbide Tubes provides all these material properties. The material has such high strength that the wall thickness of the thermocouple protection tubes can be minimized. This is essential to detect even tiny temperature differences and permit an effective automatic control loop.

Silicon Carbide Tubes For Heat Exchangers

Hexoloy® SiC Heat Exchanger Tubes give you distinct advantages Saint-Gobain offers Hexoloy silicon carbide chemical process heat exchanger tubing as a superior alternative to tubes made of metals, glass and othermaterials. Hexoloy SiC is a single-phase, sintered alpha silicon carbide offering high purity, fine grain size and extremely low porosity. Hexoloy SiC tubes offer distinct advantages to enhance the performance of shelland tube heat exchangers used in demanding applications from chemical processing to refineries.

Excellent Thermal Conductivity
Hexoloy SiC's thermal conductivity is almost equal to that of commonlyused graphite tubes and far better than all other tube materials available.Its thermal conductivity is twice that of tantalum, 5 times that ofstainlesssteel, 10 times that of Hastelloy and 15 times that of glass. The result ishigher efficiency while requiring less heat transfer area.Meets Tough StandardsHexoloy SA SiC is approved for use by the followingauthorities:

• WRC, Water Byelaws Scheme (U.K.)
• DVGW, German Federal Health Office
• FDA, Non Food Additive.
These tubes come in OD of 19 mm and 14 mm and lengths upto 15 ft or as desired. MOQ norms are applicable on this.

Sapphire Tubes

Sapphire tubes are the material of choice for the protection of high-temperature thermocouples in corrosive environment.

Single crystal sapphire tubes represents a perfect durable alternatice to alumina ceramics (polycrystalline corundum ceramics). Unlike ceramics, single crystal provides 100% gas tightness and higher resistance against corrosion. Customers benefits from higher reliability and from prolonged periods between thermocouple replacements (typically 4x longer) and system shutdowns.

Key properties

100% gas-tightness - no pores, perfect environmental insulation prevents the diffusion of ambient atmosphere to the thermocouple
High resistance to aggressive environments
Operating temperatures up to 2000°C - sapphire tubes maintain their characteristics and shape up to its melting point, unlike ceramicr, sapphire tubes do not bend at high temperatures
High operating pressures - sapphire tubes generally withstand dozens bar of pressure
Outstanding electro-insulation properties

Sapphire thermocouple set consists of the outer one-side sealed protective sapphire tube and one or more inner capillaries used for insulation of branches of the thermocouple.

Thermocouple wire protection

Branches of thermocouple must be electrically insulated and protected against high-temperature corrosion. Even very low concentration of some substances (lead, ...) significantly shorten lifetime of the thermocouple wire. Typically, thermocouple is inserted to ceramic and/or metallic sheath. These materials are chosen according to temperatures and chemical composition of the environment. Sapphire tubes successfully substitute the ceramics tubes that are not resistive against diffusion of metals.

Tempered Sapphire Properties Technology Technical data

Lead oxide diffudes through multiple ceramic tubes.

Lead oxide is stopped by the single crystal sapphire tube outside protection tube remains perfectly intact.

Durability of thermocouples protected by single crystalline sapphire tubes is much higher then in the case of standard ceramics tubes. Even protective tubes of small diameters are sufficiently strong and high temperature resistant. The sapphire caps for thermocouples are the economical choice in many processes and applications such as:

• refineries

• cracking units

• combustion reactors

• incinerators

• chemical industry

• semiconductor industry

• glass industry

Hexoloy Tubes for Sulphur Recovery Units

Hexoloy SiC is produced by pressure-less sintering of submicron silicon carbide powder in a proprietary extruding process. The sintering process results in a self-bonded, fine grained (less than 10 m) SiC product. Densities of fired parts are consistently in excess of 95 percent of the theoretical density of silicon carbide (3.21 g/cm3). Extremely hard and lightweight, Hexoloy silicon carbide has a high resistance to corrosion, high temperatures and thermal shock while also having a high thermal conductivity. This makes Hexoloy an ideal material for temperature sensor tubes in a variety of traditionally challenging environments such as incinerators, chemical processing and furnaces.

The silicon carbide tubes exceeded our expectations in durability and performance under extreme conditions. Highly recommended!
