FAQ
Q: What's the difference between forged and plate flanges?
A: Forged flanges offer superior grain structure and mechanical strength compared to plate-cut alternatives. They perform better under high-pressure and temperature cycles.
Q: Can you provide material test reports?
A: Yes, we supply EN 10204 3.1 certificates with chemical composition and mechanical property data for each heat number.
Q: What's your minimum order quantity?
A: Stock items start from 10 pieces. Custom specifications require MOQ discussion based on size and grade requirements.
Q: Do you offer machining services?
A: We provide drilling, tapping, and custom face finishing. Send your drawings for quotation within 24 hours.
Q: How do I verify flange quality upon arrival?
A: Check marking codes against MTC documentation. Measure critical dimensions and inspect surface condition. Third-party inspection is recommended for large orders.
