Product Overview
A Welding Neck Flange is a pipe connecting fitting characterized by a tapered neck that is joined to the pipe via a butt weld. This design makes it suitable for piping systems operating under high pressure, high temperature, and where stringent requirements for connection reliability exist. It is a critical and widely used flange type in industrial piping for sectors such as petrochemicals and power generation.
Product Features
-
Optimized Structure, High Strength: Its tapered neck design provides a smooth transition from the pipe to the flange, effectively reducing localized stress concentrations and enhancing load-bearing capacity and fatigue resistance.
-
Reliable Connection, Excellent Seal: The butt weld connection to the pipe results in high-quality weld integrity, achieving a connection strength close to that of the pipe itself. Precision-machined facing (commonly Raised Face - RF or Ring-Type Joint - RTJ) allows for a reliable seal when used with an appropriate gasket.
-
Standardized Application, Strong Compatibility: Manufactured in accordance with international or industry standards such as ASME B16.5 or HG/T 20592, these flanges feature uniform specifications and dimensions, ensuring good interchangeability.
Main Applications
This type of flange is primarily used in demanding service conditions and critical pipelines. Typical applications include:
-
High-Temperature and High-Pressure Piping: Process lines and high-temperature steam lines in petrochemical plants and thermal power stations.
-
Piping for Toxic, Flammable, or Explosive Media: Chemical and natural gas transmission pipelines requiring zero leakage.
-
Long-Distance Pipelines and Key Facilities: Station yards and pump/valve connection points on oil and natural gas transmission pipelines.
