- Raw material verification
- Dimensional inspection based on drawing tolerances
- Flatness and sealing surface checks
- Final visual inspection and documentation before shipment
This ensures that the paddle spacer fits perfectly into the customer’s pipeline system and performs safely during operation.
Typical Applications
Super duplex paddle spacers are commonly used in:
- Oil and gas pipeline systems
