Flange
Flanges supplied by Vulcan Metals Shanghai Co., Ltd. are manufactured in carbon steel ASTM A105 and stainless steel grades 304 and 316, conforming to ANSI B16.5, ANSI B16.47, API 605, and DIN/EN 1092 standards. These include weld neck, slip-on, socket weld, and blind configurations, each machined to precise bore, face, and bolt hole dimensions for industrial piping systems. The material composition meets specified chemical and mechanical requirements under ASTM standards, with forging as the primary forming method to ensure structural integrity.
Carbon steel flanges are typically used in high-pressure, moderate-temperature environments such as oil and gas pipelines, while stainless steel variants resist corrosion in chemical processing and water treatment applications. The alloy content in 316 stainless steel includes molybdenum for enhanced resistance to chlorides, making it suitable for marine or coastal installations. Flanges are supplied with standard raised face or flat face finishes, and surface roughness typically falls between 125 to 250 microinches Ra, consistent with industry norms for gasket sealing.
These flanges are procured by engineering firms managing pipeline projects in energy, petrochemical, and power generation sectors. Buyers typically order in batches of 50 to 500 units, depending on project scale. Packaging is done in wooden crates or steel pallets with rust inhibitors for sea freight. Delivery terms are commonly FOB Shanghai or CIF, with lead times averaging 4 to 6 weeks after order confirmation. Certifications such as material test reports (MTRs) are available upon request.

Sourcing Flange from Vulcan Metals Shanghai Co., Ltd. - China Import Guide
Before ordering flanges from this supplier, verify the material grade certification (ASTM A105, A182 F304/F316), pressure class, and face finish against your project specifications. Request material test reports for each batch, and confirm that the flanges conform to the exact standard cited - ANSI B16.5, B16.47, or DIN - since mismatched standards can cause installation failures. Do not assume compliance without documentation.
Confirm Incoterms such as FOB Shanghai or CIF destination port, as shipping terms vary by order size. Lead times typically range from 4 to 6 weeks for standard sizes but may extend for custom dimensions or large volumes. Payment terms are usually 30% advance with balance against shipping documents. Ensure packaging is rust-protected for sea transport, especially for carbon steel flanges.
Conduct a pre-shipment inspection for dimensional accuracy, surface finish, and absence of forging defects such as laps or cold shuts. Verify bolt hole alignment with a go/no-go gauge. Request copies of inspection reports and packing lists. Retain sample flanges for future reference, especially if used in regulated industries where traceability and documentation are mandatory for compliance.
