Products classified under HTS 7305.31.40.00
Longitudinally Welded Steel Water Pipe 24-inch
A large-diameter, longitudinally welded pipe made of nonalloy steel with an external diameter of 610 mm, used for municipal water distribution systems. It falls under HTS 7305.31.40.00 as it is a welded tube with circular cross-section exceeding 406.4 mm, constructed from iron or nonalloy steel, not suitable for oil/gas due to its specifications. These pipes are essential for infrastructure projects requiring durable, corrosion-resistant conveyance.
Welded Nonalloy Steel Culvert Pipe 30-inch
Heavy-duty, longitudinally welded steel pipe of nonalloy steel, 762 mm external diameter, designed for stormwater drainage and culverts in road construction. Classified under HTS 7305.31.40.00 for its large circular cross-section, welded closure, and iron/nonalloy steel material. Provides structural support in civil engineering applications.
Large Diameter Welded Steel Sluice Gate Pipe 48-inch
Longitudinally welded pipe from nonalloy steel, external diameter 1219 mm, used in irrigation and flood control sluice systems. HTS 7305.31.40.00 applies due to its welded construction, circular profile over 406.4 mm, and nonalloy steel composition. Ideal for high-volume water management.
Nonalloy Steel Penstock Pipe 36-inch Welded
Longitudinally welded, 914 mm diameter pipe of iron or nonalloy steel for low-pressure penstocks in small hydroelectric setups. Fits HTS 7305.31.40.00 as a large, circular, welded tube not primarily for oil/gas. Balances cost and durability for water conveyance.
Welded Steel Intake Pipe 42-inch for Pumping Stations
