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.

LADHANI METAL CORPORATION Duplex 31803 Threaded flanges look very similar to Slip-On flanges but the main difference is that the threaded flange has been was bored out to match a specific pipe inside diameter. The backside of this center opening is then threaded with the relevant-sized tapered pipe thread. Duplex 31803 Threaded Flanges can be used in very high pressure services and their major advantage is that they can be assembled without welding. Features: Corrosion resistant Easy to install, owing to open pipe threads Durable construct Specification: Size : 1/2"NB TO 60"NB IN Class : 150 LBS, 300 LBS, 600 LBS, 900 LBS, 1500 LBS, 2500 LBS DIN Standard ND-6, 10, 16, 25, 40 Etc.
