Long Weld Necks

As part of our commitment to offering as many pipe flanges as possible, PPI is a leading supplier of the long weld neck flange design. Characterized by a long vertical “neck” in the center, long weld neck (also known as “LWN” flanges) are a specialty product intended to simplify the processes of many fabrication and manufacturing applications. They are seamless products that are specifically designed to be compatible with standard B16 flanges, which we also manufacture.

Standards for Long Weld Neck Flanges

Rather than being manufactured to a published specification, long weld neck flanges are manufactured to an industry standard; with every order, PPI makes these flanges according to the highest industry standards there are. We provide you with a seamless product that features a nominal bore and a heavy wall thickness; these features make our long weld neck flanges the most ideal choice for your application.

You may find that using seamless, forged long weld neck flanges eliminates the need for:

• Reinforcing pads (re-pad)
• Pipe spools
• Various welding processes and inspections

We are able to provide a wide range of long weld neck flange sizes; to inquire about a specific size of LWN flange, please contact us with your request. For your convenience, we also offer anchor flanges, reducing flanges and orifice flange unions. Should you require any of these other varieties, please don’t hesitate to ask us about them.
