Product Description

Product Description

Product Name:  China manufacturer forged A694 F65 Long Welding Neck Flanges

The extended neck of LWN flanges serves multiple purposes. First, it provides reinforcement to the flange, making it capable of withstanding higher pressures and temperatures. The longer neck also allows for a larger welding surface area, resulting in a stronger and more reliable connection between the flange and the pipe. This extra length also facilitates easier welding access, particularly in applications where the pipe is buried or in tight spaces.
