We focus on continually improving the quality of our processes. With recent investments in an intermediate finishing line, water-blast descaling process, and continuous induction thermal treat facility, we strengthened our ability to offer quality, customized solutions. Our approach to manufacturing integrates our melting, rolling, piercing and finishing operations, helping to ensure quality control from start to finish. Our seamless mechanical tubing processes include piercing (rotary forging), thermal treatment, and testing and finishing.
Mechanical Steel Tubes
Mechanical steel tubes are essential for a variety of industrial applications requiring high strength, precision, and durability. The choice of material—whether carbon steel, alloy steel, or stainless steel—depends on the specific requirements of the application, such as mechanical properties, corrosion resistance, and ease of machining.
High-Pressure Cylinder Pipes
JIS G3429 sets rigorous standards for seamless steel pipes used in high-pressure gas cylinders, ensuring they possess the necessary strength, toughness, and durability. By adhering to these standards, manufacturers can produce high-quality, reliable cylinders that safely store and transport gases under high pressure, meeting the demands of various industrial, medical, and safety applications.
G3429 Seamless Gas Cylinder Pipes: STH11, STH12, STH21, STH22
STH11 and STH12 are cost-effective for general-purpose cylinders, while STH21 and STH22 excel in high-pressure, high-temperature applications due to their Cr-Mo composition. Dimensional tolerances and chemical compositions are tightly controlled to ensure safety and performance.
