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.

Blind flange is also called blind plate, and its correct name is flange cover. It is a flange without a hole in the middle, used to seal the pipe plug. There are many types of sealing surfaces, including flat surface, convex surface, concave-convex surface, tongue-and-groove surface, and ring connection surface.
