Long Weld Neck
Long weld necks are similar to weld neck flanges, with the exception that the neck is lengthened and acts like a boring extension. Long weld neck flanges are generally used on vessels, columns or barrels. In critical applications where working temperature, mechanical stress, and corrosion factors are elevated, heavy barrel (HB) and equal barrel (E) types might be utilized for their thicker barrels and increased support capacity.
