Introduction

Welding neck flange also called WN flange,is a flange with a neck butt welded to the pipe.Welding neck flange is not easy to be deformed, well sealed, and widely used. Welding neck flange is suitable for pipelines with large fluctuations in pressure or temperature or pipelines with high temperature, high pressure≤25.0Mpa and low temperature.It is also used for conveying expensive, flammable and explosive media on the pipeline with nominal pressure around PN16MPa.Butt weld flanges are the most commonly used connection for stainless steel valves.The sealing surface of butt welding flange RF,FF, MF and so on.


WN flange is not easy to deform, the sealing is good, and the price is relatively cheap. It is suitable for occasions with high pressure, high temperature and large pipe diameter.

As the welding neck flange manufacturers in China, EATHU can also supply OEM flanges according to customers’drawings or designs.
