ASTM N10276 RF Weld Neck Flange 3" 300# High Performance Alloy Steel Flanges

Product Description

These high performance weld neck flanges are made from ASTM N10276 nickel‑based alloy steel, featuring excellent corrosion resistance, high temperature stability and superior mechanical properties. Designed with RF raised face and Class 300 pressure rating, the 3‑inch flanges ensure tight sealing, high pressure resistance and long service life in harsh industrial environments. They are widely used in corrosive piping systems where reliability and durability are critical.

Key Parameters

Material: ASTM N10276 Alloy Steel
Type: WN Weld Neck Flange
Face Type: RF Raised Face
Size: 3 Inch
Pressure Class: 300#
Standard: ASME B16.5
Surface: Passivation, anti‑rust coating
Features: High performance, corrosion resistant, high strength, leak‑proof
Application: Chemical, petrochemical, offshore, marine and high‑corrosion piping systems

Application

Widely applied in chemical processing, refineries, offshore platforms, desalination plants, pharmaceutical and environmental engineering piping systems. Suitable for pipelines conveying acids, alkalis, chloride media and other corrosive fluids.

Product Advantages
