Product Overview
Heavy-Wall Nozzle Neck Forging belongs to a family of forged tubular connections used in pressure equipment and heavy piping interfaces. In practical projects, purchasing decisions are normally driven by wall-thickness reliability, transition geometry, weld-end allowance, and the ability to control deformation during heat treatment and rough machining.
This product is intended for more demanding nozzle positions with thicker walls, higher operating loads, or larger sizes. The forging route is selected to support better material continuity through the neck zone and to reduce the risk associated with heavy machining and subsequent welding into the vessel body.

Key Advantages
Heavy-Wall Integrity — The forged wall section helps improve structural reliability in transition zones, branch connections, and pressure-retaining parts.
Controlled Machining Allowance — Allowance is arranged for bevels, faces, bores, and weld preparation so the customer can finish the connection without sacrificing sound material.
Better Weld Integration — Proper forged preforms support improved fit-up and more stable welding performance in vessel and piping assemblies.
Inspection Readiness — These parts can be supplied with UT, PMI, hardness checks, and project documentation suited to pressure-equipment work.
Drawing-Based Adaptability — Straight sections, neck contours, and transition profiles can be arranged to match project geometry rather than forcing a standard layout.
Typical Applications
• Large or thick nozzle connections
• Refinery and process vessels
• High-load branch zones
• Special pressure-equipment nozzles
Supply Scope and Inspection
Heavy-Wall Nozzle Neck Forging can be supplied as a forging blank, heat-treated forging, rough-machined forging, or semi-finished part according to the customer’s process route. Where the project requires closer dimensional control, additional OD/ID/facing, journal, bore, or drilling work can be incorporated before shipment.
For inspection-sensitive orders, Yongxinsheng can coordinate ultrasonic testing, MT/PT where applicable, PMI, hardness checks, mechanical testing, marking, EN 10204 3.1 documentation, and third-party witness arrangements. This makes the product suitable not only for general industrial procurement but also for project-based orders with stricter quality-document requirements.
