Different welding forms: The welding form of neck flat welded titanium flange pipe and titanium flange is fillet welding, while the welding form of the neck butt welded flange and pipe is girth welding; 2. Different materials: the material of the necked flat welding flange is made of ordinary titanium plate with a thickness that meets the requirements, while the material of the necked butt welding flange is mostly machined from titanium forgings; 3. the nominal pressure is different: the nominal pressure of the necked flat welding flange is: 0.6---4.0MPa, and the nominal pressure of the necked butt welding flange is: 1--25MPa; 4. Another point is that the welding seam between the necked butt-welded flange and the connection pipe belongs to type B seam, and the welding seam between the necked flat-welded flange and the connection pipe belongs to type C seam. And the non-destructive testing after welding is different; 5. The necked flat welding flange and the necked butt welding flange cannot be replaced at will. From a manufacturing perspective, the necked flat welding flange (SO is the abbreviation of Slip On) has a large inner diameter, which means that the weight is light and the cost is low. Neck butt welding flanges (WN is the abbreviation of Welding Neck) with a nominal diameter greater than 250mm need to be tested, and SO flanges do not need to be tested, so the cost is low.
