High Light ASME B16.5 welding neck flangeSuper Duplex Stainless Steel flange1500# alloy steel flange

ASME B16.5 1500# Welding Neck Flange UNS S32750 Super Duplex Stainless Steel

 

 

This high-performance super duplex stainless steel welding neck flange is strictly manufactured in accordance with ASME B16.5 standard, crafted from premium UNS S32750 super duplex stainless steel, featuring a welding neck (WN) design and a high pressure rating of 1500#. It is engineered for extreme harsh industrial pipeline environments, delivering superior corrosion resistance, high strength, and reliable leak-proof performance for critical high-pressure applications.
 
UNS S32750 (also known as F53) is a high-alloy super duplex stainless steel, combining the advantages of austenitic and ferritic stainless steels. It boasts exceptional resistance to pitting, crevice corrosion, stress corrosion cracking, and general corrosion, even in aggressive media such as seawater, acidic solutions, and industrial chemicals. With high tensile strength, yield strength, and fatigue resistance, it can withstand long-term operation under high pressure (1500#) and harsh temperature conditions, outperforming conventional stainless steels in demanding scenarios.
 
The welding neck design ensures a seamless, smooth transition between the flange and pipeline, minimizing stress concentration and enabling full penetration welding. This design enhances structural integrity, prevents fluid turbulence, and ensures a permanent, secure connection that can withstand high pressure and thermal expansion. The flange is precision forged and machined, with strict dimensional accuracy, a smooth sealing surface (RF, RTJ available on request), and consistent material uniformity, ensuring tight sealing and compatibility with standard pipeline components.
 
Widely applied in offshore oil and gas, marine engineering, chemical processing, desalination plants, and high-pressure pipeline systems where corrosion resistance and high strength are critical. All flanges undergo rigorous quality control, including chemical composition analysis, mechanical performance testing, pressure testing, and dimensional inspection, fully complying with ASME B16.5 standards and international industrial requirements.
 
Key Specifications:
 
  • Standard: ASME B16.5
  • Material: UNS S32750 (F53) Super Duplex Stainless Steel
  • Type: Welding Neck Flange (WN)
  • Pressure Rating: 1500#
  • Size Range: DN15 - DN600 (custom sizes available)
  • Face Type: Raised Face (RF) as standard, Ring Type Joint (RTJ) optional
  • Application: Offshore, petrochemical, desalination, chemical, marine, high-pressure piping systems
 
With outstanding durability, stable performance, and excellent interchangeability, it provides a cost-effective and reliable connection solution for high-pressure, high-corrosion industrial pipeline projects.
