There are three main points:
1. The welding seam forms are different: the welding seam form of the titanium flange pipe with neck flat welding and the titanium flange is a fillet weld, and the welding seam form of the neck welding neck flange and the pipe is a circular weld;
2. The materials are different: the material of the neck welded flange is made of ordinary titanium plate with a thickness that meets the requirements, and the material of the neck welded flange is mostly machined from titanium forgings;
3. Different nominal pressures: the nominal pressure of the neck-welded flange is: 0.6---4.0MPa, while the nominal pressure of the neck-welded flange is: 1--25MPa;
4. One more point, the welding seam with the neck butt welding flange and the connecting pipe belongs to category B seam, and the welding seam with the neck flat welding flange and the connecting pipe belongs to category C seam, and the non-destructive testing after welding is different;
5. The flat welded flange with neck and the butt welded flange with neck can not be replaced casually. In terms of manufacturing angle, the large internal welded flange with neck (SO is the abbreviation of SLIP ON) means that the weight is small and the cost is low. In addition Welding flanges with necks with a nominal diameter greater than 250mm (WN is the abbreviation of WELDING NECK) to be tested, SO flanges do not need to be tested, so the cost is low.
