Long Weld Neck Flange Definition
In general, long welding neck flanges are called high hub flanges and are designed to transfer stresses to the pipe, thereby reducing stress concentrations at the base.
Known also by high-hub and tapered hub flanges, weld neck flanges are a type of flange. Two types are available. The regular type is suitable for pipes. The long type is unsuitable for pipes and is used for process plants. A weld neck flange is a circular fitting with a protruding rim around the circumference. These flanges are usually butt welded to pipes after being machined from forgings. A series of drilled holes allow the flange to be bolted to another flange.
Welding Neck Flanges (abbreviated as LWN) are similar to standard Welding Neck Flanges, but their “Neck” extends significantly. Often used as nozzles for barrels and columns, this type of barrel has a different shape and a thicker wall. The Equal LWN Barrel (E) and the LWN Heavy Barrel (HB) have a different shape.
Our company has earned a reputation for being a leading manufacturer, exporter and supplier of a wide range of Long Weld Neck Flanges. The offering Long Weld Neck Flanges is designed with utmost precision and in accordance with the international quality standards.
The Long Welding Neck flanges are individually covered in order to ensure premium quality materials are retained and there are no damages in the final stages of production. We also ensure prompt delivery and quality control.
Flanges with Long Welding Necks have imprints to identify the specifications of the pipes.
