1. Product Description

A Long Weld Neck Flange (LWN Flange) is a type of piping component specifically designed for high-integrity connections. Its defining feature is an extended tapered hub (neck) , which is connected to the pipe via a butt weld . This design is engineered to provide exceptional strength and is typically manufactured from forged and heat-treated materials for superior mechanical properties . It is primarily used to connect pressure vessels, heat exchangers, and pumps to piping systems, or to connect piping segments to one another .
 
2. Key Product Parameters
The table below summarizes the essential technical specifications for Long Weld Neck Flanges:
Parameter Details
Types & Codes Long Weld Neck Flange (LWN), High Hub Flange
Applicable Standards ASME B16.5 , HG/T 20615-2009 (American Class Series) , Client-specific drawings
Nominal Diameter (DN/NPS) Wide range available, commonly from 1/2 inch (DN15) to 24 inches and larger
Pressure Ratings American System (Class): Class 150 to Class 2500 . Suitable for high-pressure applications .
Sealing Face Types Raised Face (RF), Male-Female (MFM), Ring Joint (RJ), among others .
Common Materials Carbon Steel, Stainless Steel (e.g., 304, 316L) , Alloy Steel .
Manufacturing Process Forging and heat treatment , precision machining via CNC .
 
3. Product Applications
Long Weld Neck Flanges are built for demanding services and are widely used in critical industries , including:
Petrochemical Plants
Oil & Gas pipelines and facilities
Power Generation
Heavy Industries
