Flange
Jinan Aowei Mechanical Equipment Co., Ltd supplies flanges in stainless steel grades 304 and 316, and carbon steel A105, conforming to ANSI B16.5 and ASME B16.47 standards. Flange sizes range from DN15 to DN1500 with pressure classes from 150 to 2500 PSI, available in weld neck, slip-on, and blind configurations. These are manufactured to precise dimensional tolerances for seamless integration into high-pressure piping systems.
The material composition of these flanges adheres to standard ASTM A182 for stainless steel and ASTM A105 for carbon steel. Stainless steel variants offer corrosion resistance suitable for chloride-rich environments, while carbon steel A105 provides strength for high-temperature applications. Surface finish typically follows ANSI B16.5 requirements, with a roughness of 125 to 250 microinches Ra. No certifications are claimed in the source data.
These flanges are used in oil and gas pipelines, petrochemical plants, and water treatment facilities where leak-tight connections are critical. Buyers include engineering contractors, maintenance departments in industrial plants, and distributors serving the Middle East and Southeast Asia. Packaging is done in wooden crates or steel bands to prevent surface damage during transit. Trade terms include FOB Qingdao and payment via T/T or L/C, with lead times confirmed upon order.

Sourcing Flange from Jinan Aowei Mechanical Equipment Co., Ltd - China Import Guide
Before placing an order, verify the material test reports (MTRs) for each batch, ensuring compliance with ASTM A182 for stainless steel and ASTM A105 for carbon steel. Confirm that the flange size, pressure class, and facing type match your piping design. Request documentation for heat treatment if the flanges are intended for cryogenic or high-temperature service. Do not rely on supplier claims without third-party verification.
Confirm the Incoterms used - FOB Qingdao is common, but CIF or CFR may be offered. Lead time varies by order size and material; standard sizes may ship in 3 to 5 weeks, while custom orders require confirmation. Payment terms are typically 30% advance and 70% against copy of B/L. Ensure packaging includes rust inhibitors and secure strapping to prevent damage during ocean transit.
Inspect flanges for surface defects, dimensional accuracy, and proper marking upon arrival. Use a caliper to verify bore and outer diameter tolerances. Check for certification of material composition and hardness. Request a copy of the inspection report from the supplier. Retain samples from each batch for future reference in case of field failures. Document all discrepancies immediately upon receipt.
