Alloy/Carbon Steel/Stainless Steel Flange
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.

Sourcing Alloy/Carbon Steel/Stainless Steel Flange from Qingdao Wokno Machinery Co.,Ltd. - China Import Guide
Before ordering, verify the material grade and pressure class against your pipeline specifications, as mismatches can lead to leaks or structural failure. Confirm whether the flanges are produced from forged bar stock or plate, as forged flanges typically offer superior grain structure and strength for high-pressure applications.
Logistics details to confirm include packaging standards (e.g., wooden crates, palletizing), Incoterms such as FOB Qingdao or CIF destination port, and lead times for custom sizes. For bulk shipments, discuss whether the supplier can provide marking per ASME B16.5, including heat numbers, size, and pressure class for traceability.
Quality checks should include visual inspection for surface defects, dimensional verification against ASME tables, and review of NDT reports. Request copies of the supplier’s PED/97/23/EC certificates if the flanges are destined for the European market, and ensure all documentation is in English or the buyer’s required language for customs clearance.
