Renowned for quality and precision focus, Nakamura makes seamless pipes in accordance with rigorous international standards, providing outstanding corrosion resistance, high pressure integrity, and outstanding durability. These pipes are best suited for challenging applications in oil and gas, petrochemical, pharmaceutical, power generation, and marine industries. Through state-of-the-art manufacturing facilities and customer satisfaction, Nakamura Stainless provides reliable, long-lasting seamless piping solutions that meet a broad array of industrial requirements.
Stainless steel seamless tubes are usually manufactured from grades like 304, 316, and 321, with 16–18% chromium, 8–12% nickel, and optional molybdenum for added corrosion resistance. Seamless tubes are manufactured by extrusion or piercing, creating uniform structure without welding, with outstanding strength and pressure resistance. These tubes have high tensile strength (500–750 MPa), superior thermal stability, and resistance to oxidation, corrosion, and stress cracking. Their smooth inner surface promotes maximum fluid flow, while their strength makes them ideal for both high-pressure and high-temperature use in severe environments.

Yes, stainless steel seamless pipes are ideal for hygienic and sanitary applications due to their corrosion resistance, smooth surface finish, and ability to prevent contamination and bacterial growth.
Stainless steel seamless pipes are generally resistant to galvanic corrosion, especially when properly passivated. However, if in contact with more anodic metals, galvanic corrosion can occur in certain environments.
Yes, stainless steel seamless pipes are highly recyclable. They can be melted down and repurposed for new products without losing quality, making them a sustainable material option.
Yes, stainless steel seamless pipes are suitable for cryogenic applications due to their excellent toughness, strength, and resistance to brittle fracture at extremely low temperatures.
Seamless stainless steel pipes are used extensively in situations where pressure integrity, corrosion resistance, and strength are essential. They are utilized in the oil and gas production industry to transport hydrocarbons at high pressure. Chemical and petrochemical facilities use them for corrosive fluid handling. They are utilized in boiler and heat exchanger systems by power plants, and pharmaceutical and food industries opt for them due to their sanitary and contamination-free fluid conveyance. Their long lifespan, leak-resistant design, and harsh temperature endurance make them a top choice for pipelines in marine, aerospace, and infrastructure applications.
