ASME SA105N Carbon Steel Self Reinforced Nozzle For High Pressure Vessels And Piping Systems
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.
