NXF DN 6-100 Class 3000- 6000 Oil Gas ASTM B637,AMS 5383 Alloy G-30 Socket Welding Olet

Alloy G-30 (Hastelloy® 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.
The Socket Welding Olet is also called branch pipe seat, saddle, and saddle-type pipe joint. It is mainly used as a reinforced pipe fitting for branch pipe connection, replacing the branch pipe connection types such as reducing tees, reinforcement plates, and reinforced pipe sections. It has outstanding advantages such as safety and reliability, reduced cost, simple construction, improved medium flow channel, series standardization, and convenient design and selection.
