从China供应商批发进口Alloy 800 Flange — FOB条款

The Alloy 800 Flange from Zhengzhou Huitong Pipe Fitting Company is fabricated from UNS N08800, a nickel-iron-chromium austenitic alloy known for its resistance to oxidation and carburisation at elevated temperatures. It maintains mechanical strength up to 1100°F, making it suitable for high-temperature service in chemical processing, petrochemical, and furnace applications. The flange is designed to ASTM/ASME standards, with sizes and pressure classes tailored to industrial piping systems.

Alloy 800 contains approximately 32% nickel, 21% chromium, and a balance of iron, offering superior corrosion resistance in both aqueous and high-temperature environments. The material’s stable austenitic structure resists stress-corrosion cracking and sigma phase embrittlement, typical in long-term service. Surface finish is precision-machined to ensure leak-proof sealing, while the flange’s geometry adheres to standard dimensions for compatibility with ASME B16.5 or B16.47 series.

This flange is primarily used in industries such as oil and gas, power generation, and heat exchangers, where thermal cycling and aggressive media are common. Buyers typically source it for high-pressure steam lines, reactor vessels, or combustion systems. Trade terms include packaging in wooden crates or pallets, with mill test certificates and origin documentation provided for customs clearance. Confirm pressure class, size, and end connections before ordering.

Zhengzhou Huitong Pipe Fitting Company is based in Jinshui District, Zhengzhou, China, with an address at No.168 Guoji Road. The supplier operates under the harbor trust tier, indicating a baseline level of verification for international trade. Response data is currently unavailable, so buyers should directly contact the company for inquiries or technical clarifications.

The company specialises in industrial pipe fittings, including flanges fabricated from high-performance alloys like UNS N08800. While the profile does not disclose production capacity or client history, the focus on Alloy 800 components suggests expertise in high-temperature and corrosion-resistant applications. Origin documentation and compliance with ASTM/ASME standards are provided to support customs and quality assurance.
