Non-standard Flanges
- Custom Engineering Flexibility: Designed and machined strictly according to customer drawings, samples, and project requirements.
- Reliable Performance: Tailored sizes, pressure classes and sealing faces provide safe, leak-tight connections in demanding conditions.
- Precision Dimensional Control: To guarantee accuracy and consistency, a three-coordinate measuring device examines important dimensions.
- Fast Sample Verification: 2pcs free samples for non-standard flanges help you validate fit and performance before mass production.
- Short Lead Time: Typical production lead time around 20 days to support urgent project schedules.
