What makes a flat face flange different from a raised face flange?

Flat face flanges have a completely flat surface on both sides, making them ideal for mating with cast iron or glass-lined equipment where a raised face would risk cracking the mating component.

Can you produce flanges for extreme temperature vessels?

Yes, we specialize in Inconel and Hastelloy alloys that maintain structural integrity from cryogenic levels up to 1200°C.

How do you ensure the flatness of the flange face?

We use high-precision CNC grinding and lapping machines, followed by a digital flatness check using laser measurement tools.

What certifications are provided with the order?

Every shipment includes EN 10204 3.1 Material Certificates, dimensional inspection reports, and NDT clearance certificates.

Do you offer custom sizes beyond ASME standards?

Yes, we provide full bespoke engineering services to create flanges for proprietary pressure vessel designs based on your CAD blueprints.

What is the typical lead time for custom alloy flanges?

Standard alloys usually ship within 2-3 weeks. For specialty alloys like Inconel or Titanium, lead times vary based on raw material availability, typically 4-6 weeks.
