A threaded flange is a flange that uses threads to connect to a pipe. When designed, it can be seen as a loose flange. The advantage is that no welding is required, and the additional torque generated on the cylinder or pipe when the flange is deformed is very small. The disadvantage is that the flange thickness is large and the cost is high. Suitable for connection of high pressure pipeline.

Threaded flange, also called threaded flange, is a non-welded flange. The inner hole of the flange is processed into pipe threads and matched with threaded pipes to realize connection. Compared with flat welding flanges or butt welding flanges, threaded flanges have the characteristics of easy installation and maintenance, and can be used for some pipes that are not allowed to be welded on site. Alloy steel flanges have sufficient strength, but they are not easy to weld, or the welding performance is not good, you can also choose threaded flanges. However, when the temperature of the pipeline changes drastically or the temperature is higher than 260°C and lower than -45°C, it is recommended not to use threaded flanges to avoid leakage.

Because the stainless steel flanges, carbon steel flanges, alloy steel flanges, plate flanges, butt welding flanges, anti-corrosion flanges, ring flanges, blind flanges, etc. provided by our company have high standards, high-quality materials and a variety of specifications, We can undertake many large, medium and small projects, coupled with our firm service attitude considering customers, which also enables our customers to have a high repurchase rate.
