Products - Metal Tube Angle Thermocouples          Return to Product Index

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 thru our Hydro pneumatic testing to check for porosity and structural integrity. Metal protection tubes are typically made with closed hot end and a threaded cold end, but they can be made with open or partially open ends and various threading configurations. We stock all high temperature and corrosion resistant alloys in a variety of pipe sizes and schedules to insure quick delivery. We purchase our pipe in mill shipments and pass the savings on to our customers. Some of the more common listed materials are shown on this page but we can manufacture protection tubes from any material required.
