Haihao Group supplies high-quality SA 106 Gr.B swage nozzle necks for global industrial applications
Haihao Group continues to demonstrate its expertise in precision-engineered piping components with the recent production of SA 106 Gr.B swage nozzle necks (extruded nozzles). These components are an essential part of pressure vessel and piping systems, offering a reliable connection between pipes and vessels under high-pressure conditions.

SA 106 Gr.B Swage Nozzle Necks
Product Overview
The swage nozzle neck shown in the images is manufactured from ASTM A106 Grade B material, known for its excellent mechanical strength, ductility, and high-temperature performance. These forged and extruded components ensure smooth fluid transition and stress distribution, minimizing the risk of failure in demanding applications.
Key Features:
Material: ASTM A106 Gr.B (Carbon Steel)
Type: Swage Nozzle Neck / Extruded Nozzle
Manufacturing Process: Hot extrusion and precision machining
Finish: Clean surface with no cracks or defects, ready for machining or welding
Applications: Pressure vessels, boilers, power plants, refineries, chemical industries, and more
Design & Function
Swage nozzle necks are typically used as integrally reinforced connections for nozzles in pressure-containing systems. They reduce the number of welded joints required and provide a tapered, conical shape that efficiently transitions pressure from the piping system to the vessel wall. The design reduces stress concentrations, ensuring better durability and reliability of the equipment.
