all kinds of flange

Forged flange:
A flange is a rib or rim used for strength, guiding or attachment to another object such as a pipe,steam cylinder,pressure vessel,etc.Pipes,tubes or vessels can be easily assembled or disassembled by using it. Besides,flanges are fit to many other compenonts,such as valves,wheels,bellows.
In different projects and designs,flanges are used in different types,commonly,including:
Welding neck flanges (WN FLANGES)

Long welding neck flanges (LWN FLANGES)
Slip-on flanges (SO FLANGES)
Plate flanges (PL FLANGES)
Threaded flanges (THR FLANGES)
Lap joint flanges (LJ FLANGES)
Tongue and groove flanges (T FLANGES/ G FLANGES)
Blind flanges (BL FLANGES)
Socket weld flanges (SW FLANGES)
Male-and-female flanges (M FLANGES/ F FLANGES)
Ring joint flanges (RJ FLANGES)
Lovekin flanges (LK FLANGES)

Reducer flanges

Orifice flanges
