Professional Supplier of Threaded Flange

A threaded flange is a flange with a thread connected to a pipe. When designing, it can be treated as loose flange. The advantage is that welding is not required and the additional torque to the barrel or pipe is very small when the flange is deformed. The disadvantage is that the flange thickness is large, high cost. Suitable for high pressure pipe connection.

Threaded flange is the inner hole of the flange processed into pipe thread, and with the pipe with thread to achieve matching connection, is a non-welded flange. Compared with flat welding flange or butt welding flange, threaded flange has the characteristics of easy installation and maintenance, which can be used in some pipelines which are not allowed to be welded on site. Alloy steel flange has enough strength, but not easy to weld, or welding performance is not good, can choose threaded flange. However, it is recommended not to use threaded flange under the condition that the pipe temperature changes sharply or is higher than 260℃ and lower than -45℃ to avoid leakage.
