Richards Thermocouple and Temperature Sensor Catalog 16

Metal Tubes - Nominal Pipe Thread (NPT)

Richards metal thermocouple protection tubes are manufactured using our special processes to maximize the tube service life. This is evident by our uniquely shaped, heavy mass tips which have been proven in the field for years. Prior to shipment, each tube goes through our Hydro-Pneumatic testing to check for porosity.

214 Maximum service temperature 2200°F (1204°C) in low stress, oxidizing atmospheres. Best over 1750°F (955°C) and to 2200°F (1204°C) short term. Excellent resistance to carburization, Ni- triding, and Chlorine attack. 316SS Maximum service temperature 1600°F (780°C) in oxidizing atmospheres. Considered better than 304SS on corrosion. 310SS Maximum service temperature 2100°F (1150°C) in oxidizing atmospheres. Resists heat scaling. Carbon Steel Maximum service temperature 1000°F (540°C) in non-oxidizing applications. Typically used in galvanizing, tin, molten Babbitt, molten magnesium, petroleum applications and water lines. HR-160 Maximum service temperature 2200°F (1204°C) in oxidizing and reducing atmospheres. Excellent resistance to sulfur, chlorides, and hot corrosion. Typically used in waste incineration. Cast Iron Maximum service temperature 1300°F (700°C) in oxidizing at- mospheres. Typically used in molten metal. Cast Iron, Coated Maximum service temperature 1300°F (700°C) in oxidizing atmospheres. Typically used in molten metal applications.
