FAQ

Q: Can Hangxin customize the DN200 forged flange according to our specific drawings and material specs?

A: Yes. As a direct manufacturer with 30+ years of expertise, we provide full OEM/ODM customization. Utilizing our 3500T hydraulic press and CNC ring rolling machines, we precisely match your engineering drawings, non-standard dimensions, and specific chemical compositions across JIS, ASME, DIN, EN1092-1, and GOST standards.

Q: How do you guarantee the structural integrity and traceability of your carbon steel flanges?

A: We enforce strict quality control under ISO9001 and CE certifications, conducting mandatory Ultrasonic Testing (UT), hardness tests, and CNC dimensional checks to eliminate internal porosity. Every shipment includes an authentic EN 10204 3.1 Mill Test Certificate (MTC) for 100% material and mechanical property traceability.

Q: What are your standard lead times, sample policies, and international trade terms?

A: Mass production is completed within 20 days post-prepayment, and standard quality-verification samples are ready in 1–2 days. We support flexible trade terms, including FOB, FCA, CFR, CIF, DDP, and DAP, leveraging our factory's strategic location just 120 km from Tianjin Xingang Port for rapid export logistics.

Q: How do you protect the DN200 flanges from rust and corrosion during ocean transit?

A: All flanges receive professional anti-corrosion surface treatments-such as industrial black painting, yellow painting, or eco-friendly anti-rust oil. Products are then sealed in moisture-proof plastic film and packed into sea-worthy, fumigation-free reinforced wooden cases or heavy-duty wooden pallets to withstand harsh maritime environments.
