Platinum rhodium thermocouple solve probe partial oxidation device in high temperature and high pressure environment

Question:

one of the major chemicals manufacturers is going through his existing probe product fault repeatedly.

cause fault is the key problem of high pressure environment, and it has a partial oxidation of natural gas into carbon monoxide ( 痘) High temperature of reaction vessel.

to measure temperature in high reactive gaseous atmosphere, to control the process and keep the plant safety. Probe must be factory reconstruction period lasts two years. Due to the furnace insulation movement probe must be considered the possibility of breakdown. Customers need to provide a complete material, process control, test and safety documents.

our scheme through the cooperation with the customer design platinum-rhodium thermocouple, even ceramic parts failure can withstand the pressure.

the design includes a thick-walled Recrystalised alumina sheathed with Inconel alloy 600 stents to forging flange welding. Using the quality approval ( ASME(九) Welder. Platinum rhodium thermocouple conductor through the porous pressure coaxial gland, provide seal under temperature. Each probe after pressure test. First stress test is conducted on the metal workpiece, hydraulic oil to 106 bar, the second test is used in the final assembly of 40 bar air mixture. We provides a complete set of documents for each probe for delivery.

to install a set of seven probes, allow the factory operation two years of movement, the whole equipment is always change at this time.

results platinum-rhodium thermocouple can satisfy the given specifications, customers are satisfied with the goods we provide. Over the years, the contract many times over, again, has added to our successful history and the ability to delight customers.
