Threaded flange refers to a type of flange that uses threads to connect with pipes. The advantage is that no welding is required,  but he disadvantage is that the flange thickness is large and the cost is relatively higher. It’s suitable for the connection of high-pressure pipelines. 

Threaded flange is a kind of non-welded flange by processing the inner hole of the flange into pipe thread and matching with the threaded pipe to realize the connection. Compared with flat welding flanges or butt welding flanges, threaded flanges have the characteristics of convenient installation and maintenance, and can be used on some pipelines where welding is not allowed on site. The alloy steel flange has sufficient strength, but it is not easy to weld, or the welding performance is not good, you can also choose the threaded flange. However, when the temperature of the pipeline changes sharply or the temperature is higher than 260℃ and lower than -45℃, it is recommended not to use threaded flanges to avoid leakage.

We HT PIPE is the manufacture that provide all kinds of  steel flanges like Threaded Flanges, Blind Flanges, Plate Flanges, Weld Neck Flanges, Slip On Flanges, Socket Weld Flanges, and so on, and also other special flanges according to the client’s requirement.
