Alumina Ceramic Thermocouple Tubes & Multibore tubes

It also has low thermal expansion, making it a suitable material for furnace use in the crucible, tube, and thermocouple sheath form. Alumina has high hardness and good wear resistance, making it a suitable material for ball valves, piston pumps, and deep drawing tools. In addition, it can be easily combined with metals and other ceramic materials using brazing techniques and metalizing. Duralox 997 alumina closed one end Ceramic Thermocouple Tubes or Single and Multibore Tubes are sintered vertically at approximately 1750 0C temperature, in oxygen atmosphere in microprocessor controlled bell-type kiln. After sintering, 100% thermocouple tubes are tested under the air pressure bar to ensure gas tightness.

Capillary tubes made of high-performance ceramic Multi-bore capillaries for measurement and control processes In spite of its thin wall-thicknesses, the dimensional soundness of artistic fine cylinders stays immaculate. Thermocouple parts can be electrically protected directed to the place of estimation through double or multi-bore vessels made of Aluminum Oxide Ceramics. Multibore tube vessels for estimation and control processes. Earthenware thermocouple tubes and Multibore tubes other than above sizes can be fabricated on demand.

Multibore Tubes

Duralox 997 re-crystallized Alumina tubes pass good electrical resistivity as well as high thermal conductivity at high temperatures. When supported adequately, they can be used up to a temperature of 1800 0C + (3272 0F) and are suitable for molybdenum and tungsten wound tube furnaces, particularly for processes requiring a tube of an impervious nature.

Pyrometer protection sheaths (closed one end) are available from 100 to 1500 mm long. Pyrometer Sheaths sizes not shown in above table can be made on request, if found feasible. Only against specific enquiry, we can offer protection thermocouple sheaths and tubes with open both ends and with flanges, price on request. Please do not fail to specify length of the sheath in your purchase enquiry.

Applications of Alumina Multibore Tubes

  • Air, gas and liquid filtration
  • Making parts for CVD, ion implants, photolithography, and semiconductor parts.
  • Ideal for products such as injector tubes, gas nozzles, and insulators in traditional industries.
  • Protector for high-temperature thermal couples.
  • Material for the chemical industry due to its high corrosion resistance.

Workable dimensional tolerances are adhered to DIN standards 40680 medium class. Tubes with close tolerances can be manufactured on enquiry. Code RC PS corresponds to Re-crystallized Pyrometry Protection Sheaths. Sheath means closed one end Pyrometer tube.

Capillary tubes made of high-performance ceramic Multi-bore capillaries for measurement and control processes In spite of its thin wall-thicknesses, the dimensional stability of ceramic capillary tubes remains untouched. Thermocouple components can be electrically insulated guided to the point of measurement via dual or multi-bore capillaries made of Aluminium Oxide Ceramics. Multibore tubes capillaries for measurement and control processes. Ceramic thermocouple tubes and Multibore tubes other than above sizes can be manufactured on request.

Shunt Reactor: Enhancing Power System Stability and Efficiency

In the realm of electrical power systems, maintaining a stable and efficient grid is of utmost importance. Amidst the various devices that contribute to this goal, the Shunt Reactor stands out as a vital player. In this article, we will delve into the world of Shunt Reactors , exploring their role, functions, and the significant impact they have on power system stability and efficiency.   Understanding Shunt Reactors Ais a type of electrical reacto  Shunt Reactor  r used in high-voltage power systems. Its primary purpose is to regulate voltage levels by absorbing or releasing reactive power. Unlike transformers, Shunt Reactors do not have primary and secondary windings. Instead, they consist of a single winding connected in parallel to the power grid. When the grid experiences an excess of capacitive reactive power, the Shunt Reactor absorbs the surplus, preventing voltage spikes and ensuring smooth operations. Conversely, during periods of inductive reactive power, the reacto
