  • Large diameter seamless steel pipes are essential components in various industries such as oil and gas, petrochemicals, and construction. They are known for their durability, high tensile strength, and resistance to corrosion, making them ideal for applications that require seamless and reliable performance. These pipes are made through a process known as hot rolling, where molten steel is forced through a mandrel to create a long, continuous pipe. They are available in a range of diameters and thicknesses, depending on the specific requirements of the application. A large diameter seamless steel pipe typically boasts a diameter of more than 100 mm. Due to their robustness and ability to withstand high pressures, large diameter seamless steel pipes are commonly used in pipelines for transporting oil and gas over long distances.
