CPC v2.1 Code: 41281

About line pipe of a kind used for oil or gas pipelines, seamless, of steel

cpc code 41281 covers line pipe used in oil and gas pipeline infrastructure. This type of seamless steel pipe is a critical component in the transportation of energy resources, playing a vital role in the global energy supply chain. As countries and industries strive to meet growing energy demands, the production and trade of line pipe like that described by code 41281 has become increasingly important to the broader economy.

Production process

Line pipe classified under cpc 41281 is produced through a seamless manufacturing process. This typically involves piercing a solid steel billet and then hot-rolling or extruding the material to create a seamless tubular product. Advanced techniques like electric resistance welding may also be employed to ensure the pipe's structural integrity and suitability for high-pressure applications.

Production inputs

The production of cpc 41281 line pipe requires several key inputs, including high-quality steel billets or ingots, specialized rolling/extrusion equipment, and precision measurement tools. Energy sources like natural gas or electricity are also necessary to power the manufacturing equipment. Additionally, skilled labor with expertise in metallurgy and pipe fabrication is an essential input for this industry.

Production outputs

The primary output of cpc 41281 is seamless steel line pipe used to transport oil, natural gas, and other energy products through pipeline networks. This pipe may be further processed, coated, or fitted with specialized connectors before being incorporated into 41282 Line pipe of a kind used for oil or gas pipelines, welded, of steel or other pipeline infrastructure. The outputs of this industry are crucial inputs for a wide range of energy, construction, and transportation 41 Metal products, machinery and equipment.
