SA-350 LF2 Self-Reinforced Nozzle for Pressure Vessels

Product Overview

SA-350 LF2 Self-Reinforced Nozzle is a forged and machined nozzle component designed for pressure vessel connections and other industrial equipment requiring an integrated reinforcement structure.

Manufactured from ASTM A350 LF2 carbon steel forgings, this nozzle can be supplied according to customer drawings, specified dimensions, connection requirements, and project technical specifications. Its self-reinforced configuration integrates the reinforcement into the nozzle geometry, potentially eliminating the need for a separate reinforcement pad where permitted by the applicable design code.

YUHONG supplies self-reinforced nozzles for pressure vessel fabrication, heat exchanger assemblies, and oil and gas processing equipment, subject to project requirements and material availability.

Product Specifications

Key Features of SA-350 LF2 Self-Reinforced Nozzles

• Integrated Reinforcement Structure

The nozzle is designed with an integrated reinforcement profile. Depending on the equipment design and applicable code calculations, this configuration can reduce the need for a separate reinforcement pad and simplify certain fabrication operations.

• Low-Temperature Carbon Steel Material

ASTM A350 LF2 is a carbon steel forging grade used for components requiring specified mechanical properties at low temperatures. The applicable material class, impact test temperature, acceptance criteria, and heat treatment condition should be confirmed against the purchase specification.

• Drawing-Based Manufacturing

Self-reinforced nozzles often have application-specific dimensions and geometries. Manufacturing can be based on approved drawings, including the required bore, neck dimensions, overall height, wall thickness, and connection details.

• Machined Connection Surfaces

Machining requirements can be specified for the bore, contact surfaces, weld preparation, and other functional areas. Final dimensions and tolerances should follow the approved drawing and applicable technical requirements.

Typical Applications

• Pressure Vessels: Nozzle connections for process vessels and pressure-containing equipment.

• Heat Exchangers: Connection components for shell-and-tube heat exchanger fabrication, where the design requires an integrated reinforcement profile.

• Oil and Gas Processing: Nozzle assemblies used in process equipment and piping connections.

• Petrochemical Plants: Components for industrial vessels and process systems.

• Industrial Equipment: Custom nozzle connections manufactured to project-specific drawings.

Manufacturing and Quality Requirements

The manufacturing and inspection requirements for SA-350 LF2 self-reinforced nozzles depend on the purchase order, approved drawings, and applicable design code. Typical requirements may include:

• Verification of material grade and heat number traceability.

• Chemical composition and mechanical property testing according to the specified material standard.

• Heat treatment and impact testing when required by the applicable specification.

• Dimensional inspection against approved drawings.

• Visual examination and additional nondestructive examination where specified.

• Material test certificates and inspection documentation as required by the purchase order.

The inspection scope and acceptance criteria should be agreed upon before production.
