Products classified under HTS 7305.11.10.30
24-inch LSAW Line Pipe for Oil Pipelines
A longitudinally submerged arc welded (LSAW) steel pipe with an external diameter of 24 inches (609.6 mm), made from non-alloy steel, designed specifically for high-pressure oil transmission pipelines. It falls under HTS 7305.11.10.30 due to its circular cross-section, welded construction, diameter range exceeding 406.4 mm but not 609.6 mm, and use in oil or gas line applications.
20-inch API 5L Grade B LSAW Gas Pipeline Pipe
Longitudinally submerged arc welded pipe, 20-inch (508 mm) external diameter, non-alloy steel API 5L Grade B, optimized for natural gas distribution pipelines with high yield strength. Classified under HTS 7305.11.10.30 for its LSAW method, size, and dedicated oil/gas line pipe purpose.
18-inch LSAW Carbon Steel Oil Transmission Pipe
Heavy-duty LSAW carbon steel pipe with 18-inch (457 mm) external diameter for long-distance crude oil transmission, featuring thick walls for pressure resistance. HTS 7305.11.10.30 applies to its welded circular construction, non-alloy steel material, and oil pipeline designation within the specified diameter range.
22-inch Non-Alloy LSAW Natural Gas Line Pipe
Robust 22-inch (558.8 mm) diameter LSAW pipe of non-alloy steel for underground natural gas mains, built to withstand corrosive environments. It matches HTS 7305.11.10.30 precisely as a welded line pipe for gas pipelines in the defined size bracket.
16-inch API 5L X42 LSAW Oil Pipeline Section
LSAW pipe section, 16-inch (406.4 mm) external diameter, API 5L X42 grade non-alloy steel, used in sectional assembly for offshore oil gathering lines. Fits HTS 7305.11.10.30 for LSAW oil/gas line pipes at the lower end of the diameter spectrum.
24-inch X52 Grade LSAW Gas Transmission Pipe
High-strength 24-inch diameter LSAW line pipe in API 5L X52 non-alloy steel for high-pressure gas transmission networks. HTS 7305.11.10.30 covers its longitudinal weld, size, and gas pipeline function.
19-inch Carbon Steel LSAW Pipeline Pipe
19-inch (482.6 mm) external diameter LSAW carbon steel pipe engineered for oil and gas gathering lines in remote fields. This product is precisely under HTS 7305.11.10.30 as longitudinally welded, non-alloy line pipe in the 406.4-609.6 mm range.
