Steel pipe without welds

Seamless steel pipes are manufactured by thrusting a piercing mandrel through a steel billet to form a hole, then processed by a rolling mill to a specified diameter and wall thickness. Formed from a single piece of steel, this process ensures the pipe's strength, structural integrity and uniformity.

Seamless steel pipes come in various production varieties designed to meet diverse industry needs with precision. The hot rolled pipes offer thick and durable walls ideal for demanding environments, while the cold rolled pipes provide smoother finishes and exact dimensions for desired applications. For projects requiring peak mechanical performance, the cold drawn seamless steel pipes deliver superior finishes and enhanced mechanical properties. Additionally, the extruded pipes are perfect for exceptionally thick wall requirements. We also offer the specialized top pipe, tailor-made for unique industrial challenges.

Seamless steel pipes are widely used in various applications as geological drilling pipes, petroleum cracking pipes, boiler pipes, bearing pipes, and high-precision structural steel pipes for automotive, tractor, and aerospace industries due to their ability to withstand higher pressures as they don’t have cracking welded points. They are particularly valuable in applications where high temperatures and pressures can degrade other types of pipes and are suitable for carrying corrosive, chemical agents even in extreme conditions.
