Seamless Stainless Steel C4 |UNS N06455|2.4610 Pipe

Hastelloy C4 Seamless Pipes are high-performance cylindrical tubes manufactured from nickel-chromium-molybdenum alloy (UNS N06455), specifically engineered to deliver outstanding corrosion resistance in highly aggressive environments. With exceptional stability in strong oxidizing media, acidic solutions, and chloride-containing processes, these alloy pipes are widely used in chemical processing, flue gas desulfurization (FGD), nuclear, and petrochemical industries.

At Tengqi, a professional manufacturer and supplier based in Fujian, China, we specialize in the precision production of Hastelloy C4 seamless pipes using advanced seamless forming and cold-finishing processes. Our pipes are available in a comprehensive range of outer diameters, wall thicknesses, and surface finishes, including both standard ASTM specifications and fully customized dimensions to meet specific project requirements.

Manufactured in compliance with international standards such as ASTM B622 and ASME SB622, our Hastelloy C4 seamless pipes offer excellent thermal stability, superior resistance to pitting and stress corrosion cracking, and long-term structural integrity under extreme temperature and pressure conditions.

To guarantee premium quality and reliability, each pipe undergoes rigorous inspection and testing procedures, including hydrostatic testing, eddy current testing, PMI (Positive Material Identification), and ultrasonic testing.

With strict quality control, competitive pricing, and reliable global delivery, Tengqi has established a strong reputation as a trusted supplier of corrosion-resistant nickel alloy seamless pipes worldwide.
