Threaded flange

Threaded flange refers to a type of flange that is connected to the pipe by threads. When designing, it can be handled as loose flange. The advantage is that no welding is needed, the additional torque to the cylinder pipeline when the flange is deformed is very small. The disadvantage is that the flange thickness is large the cost is high. Suitable for connection of high pressure pipelines.

Threaded flange is a non-welded flange, which processes the inner hole of the flange into pipe threads connects with a pipe with threads to achieve connection. Compared with flat welding flanges butt welding flanges, threaded flanges have the characteristics of convenient installation maintenance, can be used on some pipelines welding is allowed. Alloy steel flanges have sufficient strength, but are easy to weld, the welding performance is good. Threaded flanges can also be selected. However, under conditions the temperature of the pipeline changes rapidly the temperature is higher than 260 ° C lower than -45 ° C, it is recommended to use threaded flanges to avoid leakage.
