2 Inch WN Reducing Flange Alloy Steel ASME B16.5 High Strength Forged

 

 

Product Description

 
These Welding Neck (WN) Reducing Flanges are made of high-quality alloy steel, manufactured in strict accordance with ASME B16.5 standard, with a nominal size of 2 inch. Designed with reducing structure for pipeline diameter transition connection, they feature high strength, good pressure resistance, stable structure and reliable sealing performance. Widely used in oil & gas, petrochemical, power plant, pipeline and industrial high-pressure piping systems.
 

Key Parameters

 
  • Material: Alloy Steel
  • Standard: ASME B16.5
  • Type: Welding Neck (WN) Reducing Flange
  • Size: 2 Inch
  • Connection: Welding Neck
  • Features: Reducing, high strength, forged, pressure resistant, reliable sealing
  • Application: Oil & gas, petrochemical, power, industrial piping, diameter transition
 

Application

 
Widely used in petroleum, natural gas, refinery, chemical industry, thermal power, long-distance transmission pipeline and other high-pressure industrial systems. Suitable for pipeline diameter changing, connection and transition between different pipe sizes.
 

Product Advantages

 
  • Comply with ASME B16.5 standard, stable dimension and good interchangeability.
  • Alloy steel material provides high strength, excellent pressure and high temperature resistance.
  • Welding neck structure ensures firm connection, uniform stress and long service life.
  • Reducing design realizes smooth transition between different pipe diameters, reducing flow resistance.
  • Forged process ensures compact structure, high density and stable mechanical properties.
  • Good sealing performance, effectively preventing medium leakage in harsh working conditions.
 

Installation & Use

 
Check flange surface and welding end before installation; clean welding parts; use professional welding process; tighten bolts evenly and symmetrically; conduct pressure test after installation to ensure no leakage.
 

Packing

 
Plastic caps, anti-rust film, foam and wooden case, suitable for long-distance ocean transportation.
