Principle of Implementation Duplex Steel S31803 Threaded Flanges
Duplex Steel S31803 Threaded Flanges is the inner hole of the flange is processed into pipe thread, and with threaded pipe matching connection, is a kind of non-welded flange. Compared with welding flanges or butt flanges, threaded flanges are easy to install and maintain, and can be used in some pipelines where welding is not allowed on site.
Alloy steel flanges have sufficient strength, but not easy to weld, or welding performance is not good, you can also choose threaded flanges. However, when the pipe temperature changes rapidly or the temperature is higher than 260 ° C and lower than -45 ° C, you are advised not to use threaded flanges to avoid leakage.
