Product Description

Long Weld neck flange dimensions are covered in ASME B16.5 – which covers Pipe Flanges and Flanged Fittings for size NPS ½” to 24” .

Long Weld Neck Flanges are like weld neck flanges, except for the neck, which is extended and acts like a boring extension.

Long weld neck flanges can be used in high pressure industrial applications, as well as high temperature situations. They are often utilized in the oil and gas or petrochemical industries.

These flanges are available in the more common lengths of 9”, 12”, and 16”, as well as any larger or smaller overall lengths to suit your needs. Contrary to popular suggestion, there is no universal “standard” length because these parts are made in accordance with the application necessary.
