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:
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.
