Steel pipes are cylindrical tubes made primarily of steel, a durable and robust alloy. They are commonly used for conveying fluids, gases, or solid materials in various industries due to their strength and resistance to corrosion. Steel pipes can be seamless (formed without a welded seam) or welded, depending on the manufacturing process.

Types :

Seamless Steel Pipes: Produced without a welded seam, seamless pipes are often used in high-pressure applications and where a smooth internal surface is crucial.

Welded Steel Pipes: Manufactured by welding steel plates or coils, welded pipes come in various forms, such as longitudinal, spiral, or electric resistance welded (ERW).

Applications :

Oil and Gas Industry: Steel pipes are extensively used for transporting oil, natural gas, and other petroleum products over long distances.

Construction: In construction, steel pipes are employed for structural support, piling, and underground utilities.

Water Supply Steel pipes are used in water supply systems for both potable water and irrigation purposes.

Industrial Processes Various industrial applications, such as manufacturing and chemical processing, require steel pipes for conveying fluids and raw materials.

Sizes and Specifications: Steel pipes come in a wide range of sizes and thicknesses to accommodate different applications. Specifications often include factors like diameter, wall thickness, and the type of steel used, such as carbon steel, stainless steel, or alloy steel.

Corrosion Protection: To enhance durability, steel pipes may be coated with protective layers such as galvanization (a layer of zinc), epoxy coating, or other corrosion-resistant treatments.

Standards: Steel pipes are manufactured according to various international standards, such as ASTM (American Society for Testing and Materials), DIN (Deutsches Institut für Normung), and API (American Petroleum Institute).
