Technicians need an accurate temperature profile of a reactor or fuel depot for safe, efficient operations. However, these high-temperature applications pose challenges for many temperature monitoring instruments. Multipoint thermometers also tend to be unwieldy, making them difficult to install and remove. The Gayesco Flex-O\u2122 multipoint thermometer rises to meet the challenging conditions found in many oil and gas applications.<\/strong><\/p>\n

As its name suggests, the Gayesco Flex-O\u2122 multipoint thermometer <\/a>by WIKA is a flexible, versatile instrument that rises to meet the challenging conditions found in high-temperature applications. This short video <\/a>gives a visual representation of the temperature monitoring instrument\u2019s many innovative design features. Here\u2019s a quick overview:<\/p>\n

Challenge #1: Curved Piping<\/h2>\n

Metals change properties when heated. In a hot reactor, a metal pipewell naturally expands. Because catalyst completely surrounds the pipe and does not give, this expansion occurs only in the void space at the top of the vessel. The result is a warped pipe.<\/p>\n

Traditional temperature monitoring devices have trouble dealing with curves in a pipewell. The <\/span>Gayesco Flex-O\u2122, however, has bimetallic strips that deflect and remain in continuous contact with the pipe wall, even when it bends in extremely high temperatures. All points of the Gayesco Flex-O\u2122 remain in touch with the inner pipe wall to constantly and quickly monitor changes in temperature.<\/p>\n

Challenge #2: Installation and Removal<\/h2>\n

Depending on the application and length of the pipewell, a multipoint temperature sensor can be very long. The length is necessary, but it makes the instrument tricky to ship, install, remove, and store.<\/p>\n

Indeed, the Gayesco Flex-O\u2122 has a customizable insertion length that can reach up to 40 meters (131 feet). But thanks to a flexible design, WIKA\u2019s multipoint thermometer can be coiled for easy packing and shipping. Installation is also uncomplicated: A cable with a flexible center guide can follow any bends in piping to reach the exact spots for temperature measurement and monitoring.<\/p>\n

When the reactor cools, the bimetallic strips return to their original undeflected state, making the entire assembly easy to remove. The Gayesco Flex-O\u2122 eliminates the need for a double-high crane. The instrument can then be recoiled and stored until it is needed again.<\/p>\n

Challenge #3: Contaminants and Corrosion<\/h2>\n

Many reactors and fuel depots are found along the coast. This means water, salt, and chemicals frequently find their way into pipewells. The contaminated gas filling the pipe can then condensate due to the differences in temperature between the hot tip and the nozzle of the pipewell. When this occurs, the results could be inaccurate temperature measurements and corrosion from chloride deposits.<\/p>\n

The Gayesco Flex-O\u2122 comes with an optional purge feature that allows technicians to blow out contaminants using a clean gas like nitrogen. This purging can be done once before turning on the reactor (and followed by closing the pipe with valves), or continuously during operations.<\/p>\n
