ASME SA105N carbon Steel Self Reinforced Nozzle For High Pressure Vessels And Piping Systems
ASME SA105N Carbon Steel Self-Reinforced Nozzle is a key connection component designed for high-pressure vessels and pipeline systems.
It is made of normalized forged steel (SA105N) and is self-reinforced by locally thickening the wall or optimizing the geometric profile, eliminating the need for traditional reinforcement plate welding.
It provides excellent performance in high-pressure vessels (such as reactors, boilers) and pipeline interfaces with a pressure of ≥5MPa.
