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.
