Rigorous 4-Step Quality Control
Every production batch undergoes a comprehensive inspection workflow:
1.Raw Material Testing: Verification of steel chemical composition via PMI (Positive Material Identification).
2.Ultrasonic Testing (UT): 100% non-destructive subsurface inspection to detect any internal cracks or laminations.
3.Dimensional & Hardness Check: Precision measurement against ASME/DIN/JIS standards.
4.Full Traceability: Every shipment is issued with an official Mill Test Certificate (MTC) compliant with EN 10204 3.1, ensuring total accountability for your engineering audits.

FAQ
Q: Can you provide a Mill Test Certificate (MTC) for the flanges?
A: Yes, absolutely. Every shipment is accompanied by an official Mill Test Certificate (MTC) according to EN 10204 3.1, detailing the chemical composition and mechanical properties.
Q: How do you prevent the flanges from rusting during sea freight?
A: We apply a professional surface treatment according to your needs: yellow anti-rust painting, black varnish, anti-rust oil, or hot-dip galvanization. Products are then securely wrapped in plastic film inside fumigation-free wooden cases.
Q: Do you support custom flange manufacturing (OEM/ODM)?
A: Yes. We can customize flanges up to DN3000 (120") or any non-standard dimensions based on your specific engineering drawings and technical requirements.
Q: What are your accepted payment terms?
A: Our standard term is 30% T/T deposit in advance, with the 70% balance settled before delivery. For long-term partners, L/C at sight is negotiable.
