Longitudinally Welded Alloy Steel Pipe for Oil Pipelines from China
This large-diameter pipe, with an external diameter over 406.4 mm, is made from alloy steel and longitudinally welded for high-pressure oil transportation. It falls under HTS 7305.31.60 due to its circular cross-section, welded construction, and alloy steel material exceeding the size threshold. Primarily used in midstream oil and gas infrastructure.
