Henan Anson Steel Co., Ltd. provides flanges in carbon steel and stainless steel 304/316, manufactured to ANSI, DIN, and JIS standards with sizes ranging from DN15 to DN2000. These components are designed for industrial piping systems in oil and gas, chemical processing, and power generation, where reliable sealing under pressure is essential. All products are either forged or machined from billet, depending on size and application.
Carbon steel flanges are typically produced from ASTM A105 or equivalent material, while stainless variants use 304 or 316 grades with chromium and nickel content aligned to ASTM A182. Flanges are available in weld neck, slip-on, blind, and threaded types. Dimensional tolerances follow standard industry allowances for large-diameter components, with DN1000+ sizes often requiring custom machining. Surface finish for sealing faces is typically 125-250 AARH, consistent with global practice.
Major buyers include engineering firms in Africa, the Middle East, and Southeast Asia that require large-volume shipments for pipeline construction. Orders are often placed for raw forgings requiring downstream machining, or as finished components with pressure ratings. Packaging is typically bulk steel strapping or wooden crates, and export documentation must include customs-compliant pressure rating declarations. MOQ and lead time are not specified and must be confirmed directly.

Steel flanges are essential pipe connection components widely used in oil and gas, chemical, water treatment, and power generation industries for joining pipes, valves, pumps and other equipment. Available in carbon steel, stainless steel, and alloy grades, they conform to ANSI, DIN, and JIS standards in sizes ranging from DN15 to DN2000. Flanges are traded globally as both raw forgings and finished machined components, with major export markets demanding strict dimensional tolerance and pressure rating documentation for customs clearance and quality certification.

Before ordering, verify material certifications for carbon steel and stainless steel grades, ensuring compliance with ASTM A105, A182, or equivalent. Confirm dimensional accuracy against ANSI B16.5 or DIN 2527 drawings, especially for DN500+ flanges where tolerances are critical. Request proof of heat treatment for carbon steel components and ensure all flanges are marked with heat number and grade as required by international standards.
Confirm Incoterms offered - commonly FOB Qingdao or CIF destination - and packaging type (wooden crate or steel strapping). Lead times are not listed but typically range from 6 to 10 weeks for large orders. Payment terms are not disclosed; buyers should negotiate LC or advance payment due to lack of verified supplier history. Ensure shipping documents include packing list with weight per crate and pressure rating declaration for customs clearance.
Conduct a pre-shipment inspection to verify flange face finish, bolt hole alignment, and absence of surface defects. Use a micrometer to check wall thickness and a caliper for bore and OD dimensions. Confirm the presence of heat number stamps and request a certificate of conformity. For critical applications, retain samples for third-party metallurgical testing. Ensure gasket surfaces are free of machining marks or scale.
