Flange
These flanges are manufactured for high-pressure fluid and gas systems using forged or cast methods, with sizes ranging from DN15 to DN2000 (1/2 inch to 80 inches). They are available in plate, lap joint, threaded, socket welding, blind, and slip-on configurations, designed to meet ANSI B16.5, ANSI B16.47, DIN, and JIS standards for global pipeline compatibility. Material options include carbon steel grades Q235A, Q235B, Q345B, ASTM A105, and SS400; alloy steels such as ASTM A694 F42 through F65; and stainless steels including 304, 304L, 316, and 316L.
The pressure ratings span 150 lbs to 2500 lbs (PN6 to PN250, 0.6 MPa to 32 MPa, 5k to 30k), matching industry requirements for critical applications. Surface finish and dimensional tolerances follow standard ASME B16.5 and MSS SP-44 guidelines. Typical machining allowances for forged flanges are ±0.5 mm on bore and outer diameter, while cast flanges allow ±1.0 mm. Material certifications for heat treatment and chemical composition are available upon request, though not pre-verified on this listing.
These flanges are primarily purchased by contractors in oil and gas, petrochemical, water treatment, and power generation sectors. Buyers typically require batch-specific material test reports and dimensional inspection reports. Packaging is in plywood cases or pallets, with custom packing available. Lead time and minimum order quantities are not specified and must be confirmed directly with the supplier.

Sourcing Flange from Hebei Xinfeng High Pressure Flange And Pipe Fitting - China Import Guide
Before ordering, verify the material grade against the required standard, such as ASTM A105 or A350 LF2, and request a certified material test report (MTR) with chemical analysis and mechanical properties. Confirm that the flange type, size, and pressure class match your piping system design. Ensure the supplier can provide traceability via heat number and that the manufacturing method (forged vs. cast) aligns with your pressure and temperature requirements.
Lead time is not stated and must be confirmed directly. Incoterms are not specified; common terms for this origin are FOB Qingdao or CIF destination port. Payment terms typically involve 30% advance and 70% against copy of shipping documents. Buyers should confirm packaging method, especially for large flanges, to avoid damage during transit. Request a sample if ordering above 100 pieces to validate dimensions and finish.
Perform a pre-shipment inspection to check flange face flatness, bolt hole alignment, and surface finish. Use a micrometer to verify bore and outside diameter tolerances. Confirm that the heat number on the flange matches the MTR. For critical applications, request a copy of the hydrostatic test report or dye penetrant inspection certificate. Retain all documentation for customs and regulatory compliance in your destination country.
