Subheadings
Products classified under HTS 7306.19.51
Chrome-Moly Alloy Steel Gas Transmission Pipe
Welded chrome-molybdenum alloy steel pipe (e.g., 5Cr-0.5Mo) for high-temperature gas transmission lines. Provides creep resistance under pressure. Under 7306.19.51 for alloy steel oil/gas line pipe.
Submerged Arc Welded Alloy Line Pipe
High-frequency or submerged arc welded alloy steel line pipe for offshore gas pipelines, with external anti-corrosion coating options. Designed for directional drilling. HTS 7306.19.51 applies to such welded alloy line pipes.
High-Yield Alloy Steel Pipeline Spool
Short-length welded alloy steel pipe spools with welded fittings for pipeline headers in oil/gas stations. Still primarily line pipe material. Covered by 7306.19.51 as other alloy line pipe.
API 5L Grade X65 Alloy Steel Line Pipe
This is a welded alloy steel pipe conforming to API 5L X65 specifications, designed specifically for high-pressure oil and gas pipelines. It features enhanced strength from alloying elements like chromium and molybdenum, with wall thicknesses typically ranging from 0.25 to 1 inch and diameters up to 48 inches. Classified under 7306.19.51 as 'other' line pipe of alloy steel used for oil or gas pipelines.
X70 Alloy Steel Welded Pipeline Pipe
High-strength X70 grade alloy steel pipe, welded and suitable for sour service in oil and gas transmission lines. It incorporates alloy elements for corrosion resistance and toughness, meeting standards like ASTM A694. Falls under HTS 7306.19.51 as other alloy steel line pipe for pipelines.
12-Inch OD Alloy Steel Gas Line Pipe
Welded alloy steel pipe with 12-inch outside diameter and 0.375-inch wall thickness, engineered for natural gas distribution pipelines. The alloy formulation provides superior yield strength for high-pressure environments. Classified in 7306.19.51 for other alloy steel line pipes used in gas pipelines.
Alloy Steel Sour Service Line Pipe
Specialized welded alloy steel line pipe resistant to hydrogen sulfide cracking in sour oil/gas environments, typically PSL2 grade. It features precise alloy control for HIC resistance. HTS 7306.19.51 covers such other alloy steel pipes for oil or gas pipelines.
24-Inch Diameter Alloy Steel Oil Pipeline Tube
Large-diameter welded alloy steel tube for crude oil trunk pipelines, with high collapse resistance. Alloyed for low-temperature toughness in arctic applications. Fits 7306.19.51 as other line pipe of alloy steel.
