Other details:

      Sheathed thermocouple cable materials are extremely important for the manufacture of sheath thermocouple. They are  firm assemblies which are being manufactured by a combined processing of the coupling wire or pure nickel wire or filigrees, organic mineral insulant, metal sleeve. It is  widely applicable for the industrial departments and sic-tech fields in all trades and professions.Our sheathed cable company is one of the largest manufactures in Shanghai, China. It may furnish various models & specifications materials.   

Features:

      Small external diameter, quick heat responsive period, may be bent, long use life, fine air-tightness, wide thermometric scope, high voltage resistant, anti-vibration, narrow mounting pipeline, may be used under bending conditions.

Material AISI316L Properties:

Corrosion resistance: Additions of molybdenum make this steel superior to molybdenum-free types as regards increased corrosion resistance to certain acids such as acetic acid , phosphoric acid, sulphuric acid and other similar acids. Furthermore, this steel is more or less insensitive to pitting corrosion and withstand salt-water and aggresive industrial media. 

Welding and mechanical properties: Suitable for all known welding techniques. Heat-treatment subsequent to welding is generally not necessary. In special circumstances when stresses from welding should be reduced to avoid stress-corrosion-cracking heat-treatment should be conducted. Highly ductile, only very sharp tools should be used for machine cutting, this steel can be polished.

Field of application: Due to its high level of resistance to corrosion and pitting corrosion this alloy is ideally suited to applications in the field of chemical instrument construction. Other fields are: nuclear power plants, reactor instrumentation, furnace cosntruction, sulphite, chemical pulp, textile, dye, fatty acid, photochemical and pharmaceutical industries.
