Seamless Pipes and Tubes
Seamless Pipes and Tubes are manufactured from solid cylindrical steel billets through processes like hot rolling or cold drawing, eliminating welded seams. They are widely used in demanding industries such as oil and gas, petrochemicals, power generation, boiler pipes, mining, mechanical engineering, automobile, and aerospace. Available in materials like carbon steel, alloy steel, stainless steel, etc., seamless pipes and tubes undergo rigorous testing to meet international standards (e.g., GB, ASTM, API). Their seamless design minimizes weak points, making them ideal for transporting fluids, gases, or structural uses under harsh conditions.
