What Are Ductile Iron Caps?

Ductile iron caps are pipe fittings that are designed to close the ends of piping systems. The Ductile Iron Caps are designed with primary alloys of carbon, silicon, iron, manganese, and other alloys. The caps are made from 90% recycled iron material. A Ductile Iron End Cap ensures they allow for waterproof sealing. The pipe caps are internally threaded to the externally threaded end. The Di Pipe Cap has good toughness and exceptional machinability. These caps prevent the entry of harsh media into them. This makes the Di Mj Cap have good tolerance to corrosive media in different environments. The caps can be availed in schedules 20 to schedule 160 and XXS. The 6 Di Cap can be threaded, welded, or fabricated as per specifications. The caps are designed in sizes of 15NB to 1200NB. The common Di Cap types are available in a round, square, rectangular, U shape, I shape, hex shapes, etc.
