Product Description

The socket flange is called SW flange for short. The basic shape of the socket flange is the same as that of the flat welding flange with neck, that is, there is a socket hole in the inner hole of the flange, the pipe is inserted into the socket hole and welded, and a circle of welding seam is welded on the back of the flange.

Due to the gap between the socket flange and Caozi, corrosion is easy to occur. The fatigue strength of socket flanges welded on both inner and outer sides is 5% greater than that of flat welded flanges and the static strength is the same. When using the socket flange, its inner diameter shall be consistent with the inner diameter of the pipe. Socket flanges are only suitable for piping of nominal diameter less than 150.

Major differences of S32760 Super Duplex Steel Socket weld Flanges

1. Fillet welds are formed by socket welding, and butt welds are formed by butt welding. The analysis of butt joint from the strength and stress of the weld is better than that of socket and socket, so it is appropriate to adopt the form of butt joint in the occasion of high pressure grade and bad use condition.

2. Socket welding is generally used for small pipe diameter less than or equal to DN40, which is more economical. Butt welding is generally used for DN40 and above. The connection form of socket welding is mainly used in the welding of small diameter valves and pipes, pipe fittings and pipes. Small diameter pipe generally has thin wall thickness, easy to mis-edge and ablative, and is more difficult to butt welding, so it is more suitable for socket welding. In addition, the socket of socket welding has the role of reinforcing, so it is also used under high pressure.

However, socket welding also has disadvantages. One is that the stress condition after welding is not good, welding is easy to occur, and there are gaps in the pipe system. Therefore, socket welding should not be used for the pipe system with crevice corrosion sensitive medium and the pipe system with high cleanliness requirements. Moreover, ultra-high pressure pipes, even small diameter pipe wall thickness is also very large, can be butt welding connection as far as possible to avoid socket welding.

3. The diameter of the former must be large and small before insertion and welding. The latter diameter can be the same or not the same. 2. The welding groove form is not the same. 3. The welding process is different. The strength is not the same after welding.

4. Those with lower pressure levels and smaller calibers are mostly socket welding, while those with higher pressure levels are often butt welding. Butt welding shall be tested 100% to ensure no leakage.

5. As the name implies, socket welding is to insert the pipe into the welding, and butt welding is directly relative to the pipe mouth welding. Generally, butt welding has higher requirements than socket welding, and the quality after welding is good, but the detection means are relatively strict. For butt welding, X-ray testing is required. For socket and socket welding, magnetic powder or penetration testing can be done (like carbon steel for magnetic powder and stainless steel for penetration). If the fluid in the pipe does not have high welding requirements, you are advised to use socket welding for easy detection
