ANSI B16.5 A105 Weld Neck Flange

ANSI B16.5 A105 Weld Neck Flange

Followings are the definition, information and application of  various types of flanges:

Weld Neck Flange Slip On Flange Blind Flange Threaded Flange
Plate/Plain Flange Socket Weld Flange Orifice Flange Spectacle Blind Flange
Lap Joint/Loose Flange Long Weld Neck Flange Reducing Flange Rolled-Forging Ring Flange
Flange-Olet Tube Sheet/Tubesheet Anchor Flange Non-Standard/Custom Flange

SPECIFICATION:

A weld neck flange (WN flange) means a flange has a neck for weld with the pipe,it is easily to recognized by their long tapered neck on the flange (The neck is also called hub in the weld neck flange).The tapered neck can supply a high strength reinforcement to support flange and pipe.It means the weld neck flange is suitable to used in high pressure and extremely temperature situation.
