SS321 Mineral Insulated Heating Cable with 2 conductor (NiCr80/20)

Feature
. Mineral insulated heating cables shall have a maximum maintain temperature 550°C and a maximum continuous exposure temperature of 650°. Higher temperature / power capabilities may also be available depending on the application.
. They are suitable for heating of pipes, vessels, tank container, flanges and valves, even they can be used in floors or concrete wall structures.
. Mineral insulated heating cables sheath with seamless stainless steel or alloy. And inner heating conductor with high purity ≥99.6% MgO insulation.
. A wide range of resistances ensures the termination of a multitude of heating cable length with various outputs (up to 200 watts per meter) and nominal voltages (300 V or 600 V).

Sheath Material of SS321
Applications: Nuclear power plants, reactor instrumentation, construction of chemical instruments, such as production of acetyl acid and nitric acids, heat exchangers, annealing furnaces, paper and textile industry, crude oil refinement and petrochemistry, fat and soap industry, food processing, dairy and fermentation works.
Max. continuous temperature: 900°C
Heat resistance: Good oxidation resistance in intermittent service to 800°C and in continuous service to 900°C. Resistant to carbon dioxide up to 650°C .
