NXF DN 15-1200 Class 150-2500 Product Type ASTM B637,AMS 5383 Alloy G-30/2.4603/UNS N06030 Threaded Flanges

Product Description

Alloy G-30 (UNS N06030) is a Ni-Cr-Fe corrosion-resistant alloy with alloying additions of molibdenum, tungsten, copper and niobium. Generally resistant to oxidizing environments, it's extremely resistant to phosphoric acid (P2O5) and thus used widely in the production of agrichemical fertilizers. It can be seen as a low-carbon variant of alloy G, with improved weldability (it's less prone to heat-affected zome carbide precipitation and hot-cracking), and ductility.Used in phosphoric acid plants, sulphuric acid service, nitric acid service, pickling operations, petrochemical operations, fertilizer manufacture, pesticide manufacture, gold extraction and nuclear waste processing.

Threaded flange refers to a flange that is connected to the pipe by threads. When designing, it can be treated as a loose flange. The advantage is that welding is not 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 is thick and the cost is high. It is suitable for the connection of high-pressure pipelines.Threaded flange is a non-welded flange that has its inner hole processed into pipe threads and is connected to threaded pipes. Compared with flat welding flanges or butt welding flanges, threaded flanges are easy to install and maintain, and can be used on pipelines where welding is not allowed on site. Alloy steel flanges have sufficient strength, but are not easy to weld, or have poor welding performance, so threaded flanges can also be selected. However, when the pipeline temperature changes sharply or the temperature is higher than 260℃ and lower than -45℃, it is recommended not to use threaded flanges to avoid leakage.
