Threaded Flange

Threaded flange refers to a flange that is connected to a pipe by thread. When designing, it can be treated with loose flanges. The advantage is that no welding is required and the additional torque on the cylinder or pipe is very small when the flange is deformed. The disadvantage is that the flange thickness is large and the cost is higher. It is suitable for the connection of high-pressure pipelines.

The threaded flange is a kind of non-welded flange that processes the inner hole of the flange into a pipe thread and connects it with a threaded pipe. Compared with flat welding flanges or butt welding flanges, threaded flanges have the characteristics of easy installation and maintenance, and can be used on some pipelines that are not allowed to be welded in the field. The alloy steel flange has sufficient strength, but it is not easy to weld, or the welding performance is not good, the threaded flange can also be selected. However, under the condition that the temperature of the pipe changes sharply or the temperature above 260°C and below -45°C, it is recommended not to use the threaded flange to avoid leakage.

Features and benefits of threaded flanges include:

Easy to install: The threaded connection is relatively easy to install, does not require special tools, and can be completed by simply tightening.

Time-saving: Compared to other connection methods, the threaded flange connection is faster, which saves installation time.

Low cost: Since the production cost of threaded flanges is relatively low, the overall engineering cost can be reduced to a certain extent.

High reliability: the tightness of the threaded flange connection is good, the connection is stable and reliable, not easy to loosen, and has high sealing.

Wide applicability: Threaded flanges are suitable for some low-pressure and low-temperature occasions, and are widely used in pipeline connection and equipment installation.

However, there are also some disadvantages of threaded flanges, such as the risk of loose threads under high pressure, high temperature, high impact load and other conditions, and it is necessary to pay attention to the selection of appropriate connection methods to ensure the safety and reliability of the project.
