常见问题

What is the primary function of a seating surface in collector nozzles?

To provide a precise sealing interface that prevents fluid leakage while maintaining system pressure integrity between connected components.

How does surface finish affect seating surface performance?

Surface finish directly impacts sealing effectiveness - smoother finishes (lower Ra values) typically provide better sealing but require more precise manufacturing, while slightly rougher finishes may accommodate minor imperfections.
