Document Type and Number:
Japanese Patent JP7115323
Kind Code:
B2
Abstract:
To provide a gas sampling pipe in which a filter for preventing molten metal dust from passing through can be appropriately updated, and gas sampling through the gas sampling pipe can be continuously operated.SOLUTION: A gas sampling pipe is for sucking gas in a container in which molten metal is stored. The gas sampling pipe has: a hollow main body section 11 that allows the sucked gas in the container to flow out of the container; and a filter section 100 that is provided at a distal end 13 of the main body section 11 that is inserted into the container and covers an opening at the distal end 13 from the outside. The filter section 100 is provided with a plurality of laminated filters 101 for allowing the gas in the container to pass therethrough and preventing molten metal dust from passing therethrough.
