Corrosion-Resistant N10276 WN RF Flange 3 Inch Class 300 Alloy Steel Flanges

Product Description
These Weld Neck flanges are manufactured from ASTM N10276 nickel‑based alloy steel, featuring outstanding corrosion resistance, high strength and excellent stability in harsh environments. Built to international flange standards with RF raised face and Class 300 pressure rating, the 3‑inch size ensures tight connection, high pressure resistance and long service life for chemical, offshore and corrosive piping systems.
Key Parameters
  • Material: ASTM N10276 Alloy Steel
  • Type: WN Weld Neck Flange
  • Face Type: RF Raised Face
  • Size: 3 Inch
  • Pressure Class: Class 300
  • Standard: ANSI/ASME B16.5
  • Surface: Anti-rust treatment, passivation
  • Features: Corrosion resistant, high strength, leak‑proof, long service life
  • Application: Corrosive industrial piping systems
Application
Widely used in chemical processing, petrochemical plants, offshore platforms, marine engineering, desalination and other high‑corrosion piping systems. Ideal for pipelines handling acids, alkalis, saltwater and aggressive media.
Product Advantages
  • Premium N10276 alloy provides extreme resistance to pitting, crevice and stress corrosion
  • Weld Neck structure reduces stress concentration and improves pipeline stability
  • RF raised face ensures reliable sealing under pressure and vibration
  • Class 300 rating delivers stable performance in medium‑to‑high pressure systems
  • Precision machining guarantees dimensional accuracy and easy installation
Installation & Use
Check flange face, bore and sealing surface for defects before installation; clean welding ends thoroughly; align accurately with matching pipe; perform professional welding; tighten bolts evenly; conduct pressure test after installation.
Precautions
Store in dry, ventilated and non‑corrosive environment; avoid collision during transport and handling; use within rated pressure and temperature; apply proper welding procedures for N10276 alloy.
Delivery
Ship within 7–15 working days after order confirmation; shipped by sea, air or express; tracking number provided.
Payment Terms
T/T, L/C, Western Union, PayPal; 30% deposit, balance before shipment.
Packing
