**1. Seamless Steel Pipes**
Seamless steel pipes are produced by extruding a solid steel billet through a die at high temperatures, creating a pipe with no joints or welds. This seamless construction ensures exceptional strength, uniformity, and a smooth interior surface, which reduces friction and enhances flow efficiency. Seamless pipes are ideal for high-pressure and high-temperature environments, such as oil and gas exploration, drilling, and transmission pipelines. They are also used in power plants for boiler tubes, in automotive manufacturing for hydraulic systems, and in aerospace for high-strength components. Their ability to withstand extreme conditions without weak points makes them a reliable choice for safety-critical applications.
**2. Welded Steel Pipes**
Welded steel pipes are made by rolling flat steel sheets or coils into a cylindrical shape and joining the edges using welding techniques like Electric Resistance Welding (ERW) or Submerged Arc Welding (SAW). Available in longitudinal or spiral seam configurations, welded pipes can be produced in larger diameters and longer lengths, offering a cost-effective alternative to seamless pipes. They are commonly used in water supply and wastewater systems, where large volumes of fluid are transported at low to medium pressure. In construction, welded pipes serve as structural frameworks, including columns, beams, and scaffolding, as well as in piling for foundation support in infrastructure projects like bridges and high-rise buildings.
This part highlights the versatility of seamless and welded steel pipes in high-pressure and large-scale applications. The next part will cover galvanized and stainless steel pipes, focusing on their corrosion resistance and specialized uses in various industries.
