Product Description
The most distinctive feature of the WN flange is a tapered long neck. The connection between this long neck and the pipeline is of the butt - welding type. The presence of the neck increases the strength and stiffness of the connection between the flange and the pipeline, and can effectively disperse the stress generated by the pressure inside the pipeline and external loads.
Sealing surface forms include Raised Face (RF), Male and Female Face (MFM), Tongue and Groove Face (TG), etc. Different sealing surface forms are applicable to different working conditions, and their main function is to ensure the tightness of the pipeline system and prevent medium leakage.
