Subheadings
Products classified under HTS 7304.19.50
API 5L X65 Seamless Alloy Steel Line Pipe
This seamless line pipe made from X65 grade alloy steel is designed specifically for high-pressure oil and gas pipelines, featuring precise dimensions and enhanced strength properties. It falls under HTS 7304.19.50 as it is a seamless tube of other alloy steel used for oil or gas pipelines, distinct from carbon steel variants. The alloy composition provides superior corrosion resistance and toughness for demanding pipeline applications.
X70 Grade Seamless Alloy Line Pipe for Gas Pipelines
X70 grade seamless alloy steel pipe engineered for natural gas transmission pipelines, offering high yield strength and resistance to sour service environments. Classified under HTS 7304.19.50 due to its seamless construction from other alloy steel (non-stainless) tailored for gas pipeline applications. It meets rigorous industry standards for long-distance energy transport.
13Cr Seamless Alloy Steel Line Pipe for Sour Oil Service
Seamless 13% chromium alloy steel line pipe designed for corrosive sour oil environments in pipelines, providing excellent resistance to H2S and CO2. It qualifies for HTS 7304.19.50 as a seamless product of other alloy steel intended for oil pipelines. The chrome content enhances durability without qualifying as stainless.
P110 Seamless Alloy Steel Line Pipe for Deepwater Pipelines
P110 grade high-collapse seamless alloy line pipe for deepwater oil/gas pipelines, engineered for extreme external pressure resistance. HTS 7304.19.50 applies as seamless other alloy steel line pipe for offshore pipeline systems. Provides premium strength for subsea installations.
API 5L X52M Seamless Alloy Line Pipe 24-inch OD
24-inch OD X52M seamless alloy steel line pipe per API 5L for large-diameter oil/gas trunklines. HTS 7304.19.50 classification for seamless other alloy steel line pipe construction. Micro-alloyed for enhanced toughness in arctic pipeline projects.
L80 Alloy Steel Seamless Line Pipe 7-inch Diameter
L80 grade seamless alloy steel line pipe with 7-inch outer diameter for oil gathering pipelines, balancing strength and weldability. Falls under HTS 7304.19.50 as seamless line pipe of other alloy steel for oil/gas transport infrastructure. Ideal for midstream applications requiring moderate corrosion resistance.
9Cr-1Mo Seamless Alloy Line Pipe for High-Temp Gas Lines
9Cr-1Mo alloy steel seamless line pipe rated for elevated temperatures in gas pipelines, offering creep resistance and oxidation protection.
