从China供应商批发进口Alloy/Carbon Steel/Stainless Steel Flange — FOB条款

This forged steel flange range covers Weld Neck, Long Weld Neck, Blind, Slip On, Socket Weld, Orifice, and Thread types, manufactured in stainless steel grades 304 and 316, carbon steel ASTM A105, and alloy steel ASTM A182 F11/F22. The components are produced to ASME B16.5 and B16.47 standards, with sizes spanning 1/2 inch to 84 inches and pressure classes from 150# to 2500#. The flanges also conform to ANSI, API, MSS, AWWA, EN1092-1, DIN, JIS, UNI, BS, and ISO standards, ensuring compatibility across international pipeline systems.

Material selection includes low-temperature carbon steel, high-yield alloy steel, and corrosion-resistant austenitic stainless steels, all sourced to meet the demands of petrochemical, power generation, and chemical processing environments. Typical surface finishes for these flanges include raised face, flat face, and ring-type joint, with machining tolerances adhering to ASME B16.5 dimensional tables. The forgings undergo non-destructive testing such as ultrasonic, magnetic particle, and liquid penetrant inspection to verify integrity before shipment.

These flanges are deployed in critical applications such as oil and gas pipelines, engineering machinery, shipbuilding, metallurgical equipment, and environmental protection systems. Buyers can request custom fabrication to match project-specific drawings, and small orders are accepted. The supplier’s ISO 9001:2000 certification, PED/97/23/EC compliance, and Bureau Veritas approvals provide documented quality assurance for international procurement. Verification of material test certificates and third-party inspection reports is recommended before finalizing bulk orders.
