Seamless line pipes are cylindrical, hollow tubes made from alloy or carbon steel, manufactured without any welding seams. They are produced through processes like hot extrusion or rotary piercing, ensuring a uniform structure and high strength.
These pipes are specifically designed for the transportation of fluids, such as oil, gas, and water, over long distances. They are manufactured to meet stringent standards, such as API 5L (American Petroleum Institute) and ASTM A106 (American Society for Testing and Materials), to ensure reliability and performance in demanding environments.
