Differences between Weld neck titanium flange and slip on titanium flange

1. 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.

The connection of wn titanium flange:

WN Titanium Flanges

There are holes on titanium flange, and bolts make the two flanges tightly connected. Flanges are sealed with gaskets. Flanged pipe fittings refer to pipe fittings with flanges.

It can be made by casting , or it can be formed by screw connection or welding. The flange connection consists of a pair of flanges, a gasket, several bolts and nuts. The gasket is placed between the sealing surfaces of the two flanges. After tightening the nut, the specific pressure on the gasket surface reaches a certain value and deforms and fills up the unevenness of the sealing surface so that the connection is tight and leak-proof.
