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.
Hexagon Nipple is also known as external screw, hexagonal external screw, etc. It is used to connect pipes of equal diameter.Made of malleable cast iron, with a nominal pressure of 1.6Mpa. Used to connect two internally threaded pipe fittings or valves with the same nominal diameter.
