NXF Pipe Fittings DN 6-DN 100 Source Factory ASTM B637,AMS 5383 Alloy G-30 Hexagon Head Plug

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.
It just Hexagon Head Plug up the unnecessary openings in the pipeline to play a sealing role. It is the same as blind plates, heads and pipe caps. Plugs, also known as pipe caps, caps, pipe covers, and blind heads, are pipe fittings installed on the external threads of the pipe ends to cover and plug the pipes. It is used to close the pipeline and has the same function as a pipe plug. It can be directly screwed on the pipe without the need for other pipe fittings.
