Carbon steel flanges
Carbon steel flanges from Yinclun Enterprise Co., Ltd. are engineered for leak-proof connections in industrial piping systems, manufactured from ASTM A105 or A350 LF2 grade carbon steel. The supplier offers sizes ranging from 1/2 inch to 48 inches, with pressure ratings spanning 150# to 2500#, compliant with ANSI/ASME B16.5 and API 6A standards. Configurations include weld neck, slip-on, blind, and socket weld types, designed for heavy-duty environments in oil and gas, petrochemical, and power generation sectors.
The material composition ensures durability under high pressure and temperature, with typical carbon content of 0.35% max and tensile strength of 550-750 MPa for ASTM A105. Surface treatments, such as hot-dip galvanizing or epoxy coating, are standard for corrosion resistance in harsh conditions. These flanges are typically paired with gaskets and bolts meeting ASTM A193/A194 specifications for a complete assembly.
Industrial buyers source these flanges for pipelines, valves, and equipment connections where reliability is critical. Common applications include refineries, water treatment plants, and chemical processing facilities. The supplier’s address in Shijiazhuang, Hebei, positions it for efficient containerized sea freight logistics. Buyers should confirm packaging, lead times, and incoterms directly with Yinclun Enterprise Co., Ltd.

Sourcing Carbon steel flanges from Yinclun Enterprise Co., Ltd. - China Import Guide
Before ordering, verify the exact material grade (ASTM A105 or A350 LF2) and pressure rating for your application, as these directly impact performance under temperature and pressure. Confirm whether the flanges are supplied as forged or cut from plate, as this affects grain structure and strength. Request mill test certificates to validate material composition and mechanical properties.
Logistics details to confirm include lead time, which can vary based on size and quantity, and the preferred Incoterm (e.g., FOB Shijiazhuang or CIF destination port). Packaging should be checked for compliance with international shipping standards, such as ISPM 15 for wooden crates. Payment terms, such as T/T or L/C, should align with your risk tolerance and the supplier’s requirements.
Conduct visual and dimensional inspections upon receipt to ensure compliance with ANSI/ASME B16.5 standards. Check for surface defects, such as cracks or corrosion, and verify bolt hole alignment. Request a third-party inspection if the order is critical or large. Documentation, including material test reports and compliance certificates, should accompany the shipment for traceability.
