Protection Tubes - Metal Pipe

 

Stainless Steel | nickel alloy | Carbon Steel | Cast Iron |

Metal pipe thermocouple protection tubes are an economical alternative to thermowells machined from solid bar stock. The also allow the protection of very long thermocouples which would not be possible with a machined thermowell. Metal pipe style protection tubes also allow the flexibility of using ceramic bead insulated thermocouples or MgO thermocouple elements.

Arklay Richards can manufacture metal pipe thermocouple protection tubes for difficult temperature monitoring and control applications with extreme heat, corrosive or abrasive environments. Metal Pipe Protection Tubes can be fabricated in a variety of metals including Austenitic and Ferritic Stainless Steels, High Nickel Alloys, Low Carbon Steel, Titanium and other specialty alloys. Metal pipe protection tubes can be made with pipe from 1/8" NPS up to 1 1/4" NPS. No matter how difficult your specific application, we can help you select the proper metal protection tubes. Simply call one of our sales engineers and state the quantity, temperature range, conditions and length of metal protection tube you require.
