Application of Stainless Steel Weld Neck Flange:
Stainless steel weld neck flange, are used to block the end of a pipe system or valve.The raised face is engineered to concentrate more pressure to a smaller area on the flange(brida de tubo),which provide an increased containment capability at higher pressures.The weld neck flange is also engineered to match the inside diameter (ID) of the joining pipe.This flange is ideal for high pressure,high heat and sub zero temperature applications.This flange is inserted and welded to the joining pipe.
A weld neck flange(brida de tubo) (also known as a high-hub flange and tapered hub flange) is a type of flange.There are two designs.The regular type is used with pipes. The long type is unsuitable for pipes and is used in process plant.A weld neck flange consists of a circular fitting with a protruding rim around the circumference. Generally processed from a forging,these flanges are typically butt welded to a pipe.The rim has a series of drilled holes that permit the flange to be affixed to another flange with bolts.
Such flanges are suitable for use in hostile environments that have extremes of temperature,pressure or other sources of stress.The resilience of this type of flange is achieved by sharing the environmental stress with the pipe with which it is welded.This type of flange has been used successfully at pressures up to 5,000 psi.
RFWN Flange (Raised Face Weld neck Flange) are one of the most commonly used flange in the piping industry.They are easy to recognize with their long tapered hub that is matched to the wall thickness (bore) of the pipe.
Weld neck flange(brida de tubo) and long weld neck flange provide reinforcement in application requiring high pressure and during low and high pessure extremes. It also helps in low cycle fatigue caused by line expansion of other variable forces.
Weld neck flange bore is manufactured to match the ID of the pipe or fitting. This creates a smooth transition to and from the weld neck flange and prevents turbulence at the welding neck. Hence it is important to specify the pipe schedule at the time of buying a weld neck flange. Weld neck flange is welded to pipe with full penetration weld and provides excellent stress distribution through tapered neck. Weld is also routinely radiographed or UT examined in critical applications.
Weld neck flange is available in both raised face and flat face configuration. Most common weld neck flanges have standard bore or extra heavy bore. Sch 120 or Sch 160 bore flanges, in heavier weights such as 600# to 1500# are also common in weld neck flange(brida de tubo).
