CPC v2.1 Code: 41283

About other tubes and pipes, of circular cross-section, seamless

cpc code 41283 covers the production of other tubes and pipes with a circular cross-section that are manufactured without seams. These seamless tubes and pipes are widely used in a variety of industries, including construction, automotive, and oil and gas. They offer superior strength, durability, and corrosion resistance compared to their welded counterparts, making them an essential component in many critical applications.

Production process

The production of seamless tubes and pipes under cpc code 41283 typically involves a process known as piercing. In this method, a solid billet of metal is heated and then pushed through a die, creating a hollow tube. The tube is then further processed through a series of rolling and drawing operations to achieve the desired dimensions and specifications. Advanced techniques, such as extrusion and hydroforming, may also be employed to produce more complex shapes and profiles.

Production inputs

The primary raw materials required for the production of seamless tubes and pipes under cpc code 41283 are various types of metals, such as 41110 Steel in ingots or other primary forms, 41120 Semi-finished products of steel, and 41131 Bars and rods, hot-rolled, in irregularly wound coils, of steel. Additionally, specialized machinery, such as piercing mills, rolling mills, and drawing equipment, are essential for the manufacturing process. Energy sources, such as electricity and natural gas, are also crucial inputs for the industry.

Production outputs

The seamless tubes and pipes produced under cpc code 41283 are used in a wide range of applications, including 41271 Tubes and pipes, of cast iron, 41272 Tubes and pipes, of steel, and 41279 Tubes, pipes and hollow profiles, of other materials. These seamless products are often preferred for their superior mechanical properties and are commonly used in the construction, automotive, and oil and gas industries, among others.
