Products classified under HTS 7305.12.10.30
Grade X42 Welded Gas Line Pipe 18 Inch Diameter
This API 5L X42 grade pipe has an 18-inch (457.2 mm) external diameter, longitudinally welded from nonalloy steel sheets for natural gas distribution pipelines. It withstands pressures up to 1000 psi and includes corrosion-resistant coatings. HTS 7305.12.1030 applies for its line pipe function, circular cross-section, and precise size specs.
508mm OD Welded Steel Gas Transmission Pipe
Precisely 508 mm external diameter longitudinally welded nonalloy steel pipe for natural gas transmission mains. Features beveled ends for field welding. Classifies under HTS 7305.12.1030 for its pipeline-specific design and dimensions.
Grade B ERW Line Pipe 16 Inch Equivalent
Electric Resistance Welded (longitudinal) Grade B pipe approximating 16-inch (406.4+ mm) OD for regional gas pipelines. Nonalloy steel construction for cost-effective deployment. HTS 7305.12.1030 based on diameter, welding, and line pipe purpose.
X52 Strength Oil Line Pipe 21 Inch
High-strength X52 API 5L longitudinally welded pipe, 21-inch (533.4 mm) OD, nonalloy steel for deepwater oil lines. Enhanced wall thickness for collapse resistance. Fits 7305.12.1030 exactly.
API 5L Grade B Longitudinal Welded Line Pipe 24 Inch
This is a longitudinally welded steel pipe made of nonalloy steel, with an external diameter of 24 inches (609.6 mm), designed specifically for oil and gas pipeline applications. It meets API 5L Grade B specifications for strength and durability in high-pressure transport of hydrocarbons. Classified under HTS 7305.12.1030 due to its circular cross-section, size range exceeding 406.4 mm but not over 609.6 mm, and use as line pipe.
Longitudinally Welded Oil Pipeline Pipe 20 Inch OD
A 20-inch (508 mm) outer diameter longitudinally welded pipe of nonalloy steel, engineered for crude oil transmission lines in onshore pipelines. It features thick walls for high-pressure resistance and is produced via submerged arc welding. Fits HTS 7305.12.1030 as line pipe of iron/nonalloy steel with external diameter between 406.4 mm and 609.6 mm.
