Product Description

Tankii thermocouple mineral insulated cable (MI cable)

Mineral Insulated Cable (MI cable), comprising a metal sheath in which the conductors are embedded in highly compressed magnesium oxide insulation.
Usually, the conductors (copper or thermocouple wires)  are embedded in MgO and pressed into a metal tube made of oxidation and corrosion resistant material. The entire combination is then rolled under pressure to achieve the desired diameter. 
Magnesium oxide makes an excellent electrical insulation material because it resists oxidation and ionizing radiation, and it is both chemically and physically stable at high temperatures. The outer sheath protects the internal conductor from heat, chemical or other environmental damage.
MI cables are designed for high-temperature applications and used wherever in a particularly strict requirements with regard to mechanical, chemical and electrical stability.

Sheath Material for MI Cable

Sheath Material	Maximum operating temperature	Material Properties	Main Applications
SS304	800ºC	Resistance to intercrystalline corrosion. Good resistance to organic acids at moderate temperatures, saline solutions, such as sulphates, sulphides and sulphites, and alkaline solutions at moderate temperatures. Good welding properties.	Used in chemical, petrochemical and fertilizer industries, and as equipment in dairy, food processing, pharmaceutical industries, in hospitals, households as kitchenware, cryogenic vessels and as heat exchanger in air conditioning refrigeration, for machinery in paper, pulp and textile beverage sectors.
SS321	800ºC	Good resistance to intercrystalline corrosion, also after welding. Good resistance to heavy oil products, steam and exhaust gases. Good oxidation resistance. Can be used continuously up to approximately 800°C. Good welding properties in all standard welding processes without the need for welding retreatment. Good ductility.	Nuclear power and reactor construction, chemical apparatus engineering, annealing furnaces, heat exchangers, paper and textile industry, petrochemical and crude oil industry, grease and soap industry, food processing industry. used for aircraft exhaust stacks and manifolds, pressure vessels, large mufflers for diesel engines, carburetors, expansions belows, stack liners, fire walls etc.
SS316	800ºC	An austenitic stainless steel with 2.0 to 3% Mo. which improves corrosion resistance and imparts hot strength characteristics. Used for applications requiring resistance to pitting corrosion. and in halogen atmospheres. Good welding properties.	Architectural trims, marine exteriors, chemical processing equipment, food processing equipment, petroleum refining equipment, pharmaceutical equipment, photographic equipment, pulp and paper processing equipment, textile finishing equipment, etc.
SS310	1100ºC	Grade 310S is a low carbon version of grade 310. 310S is less prone to embrittlement and sensitization in service. Good resistance to oxidation and sulphidisation. Due to the high content of chromium, the material is resistant to oxidizing hydrous solutions and has good resistance to chlorine-induced tension crack corrosion. Good resistance in cyanide smelts and neutral salt melts at high temperatures. Not susceptible to green mould. Good welding properties. It is recommended to weld with low heat impact. Apply solution annealing after welding to avoid the danger of intercrystalline corrosion.	Boilers and blast furnaces, cement and brick kilns, glass production, crude oil and petrochemical industries, furnace construction and power stations. Kilns, Heat Exchangers, Radiant Tubes, Muffles, retorts, annealing covers, Tube hangers for petroleum refining and steam b o i l e r s , Co a l g a s i f i e r i n t e r n a l components, Saggers, Furnace parts, conveyor belts, rollers, oven linings, fans, Food processing equipment, Cryogenic structures.
Inconel 600	1100ºC	Good general resistance to corrosion, resistant to tension crack corrosion. Excellent resistance to oxidation. Not recommended with gases containing CO2 and sulphur above 550°C and sodium above 750°C. In air, resistant up to 1100°C. Good welding properties for all types of welding processes. Excellent ductility even after long-term use.	PWR,  n u c l e a r p o w e r, f u r n a c e construction, plastics industry, heat treatment, paper and food processing industries, boilers, aircraft engines.
