Long Weld Neck Flange
Brief Introduction:
Flanges include integral flanges, loose flanges and arbitrary flanges, of which long weld neck flanges are a form of integral flanges, while loose flanges and arbitrary flanges can also be designed with long Neck Flange .
Long weld neck Flange is also called Long Welding Neck Flange, long welded flange or long neck flange.
Difference Between Neck Butt Welding Flange and Integral Flange:
Neck butt welding flanges and integral flanges are welded by butt welding, and both have a long neck. How to distinguish between necked butt welding flanges and integral flanges in terms of appearance size and use? From the appearance point of view, the overall flange pipe end is thicker than the butt welding flange pipe end, and the inner diameter of the overall flange is the same as the nominal diameter except for PN1.6MPa and DN450 or more. The height of the neck of the overall flange is higher, and the thickness of the wall thickness is relatively thick, which can be clearly seen by the reference standard of the flange. From the application point of view, the integral flange is the flange that is connected with the equipment, such as the flange on the valve. This flange is integral with the valve and is not connected by welding. Integral flanges are mostly used in the manufacture of equipment, and are hardly used in pipeline design. The butt welding flange with neck is used in conjunction with valves, pumps and other equipment, and is welded to the pipeline. The size of the tail interface is consistent with the outer diameter and wall thickness of the corresponding pipeline/piece, and can be directly butt welded.
