Malleable iron fittings are commonly used in residential and commercial plumbing systems due to their strength, corrosion resistance and ability to be joined by threaded connections. Let’s explore these fittings in more detail.
Malleable Iron Fittings Dimensions
Malleable iron elbows, tees, couplings and nipples are available in various standard pipe sizes from 1/2″ up to 6″. Their dimensions match outside pipe diameters to ensure proper fit within systems.
Ends are threaded with commonly used tapered threads like NPT which provide gas-tight seals when connected. Dimensions conform to industry standards like ASME B16.3 and ASTM A197.
Malleable Iron Fittings Are Used With
Due to their threaded joints, malleable iron fittings mesh seamlessly with black iron, galvanized steel and occasionally copper piping applications.
They are rated for use with natural gas, water, steam, air, oil and other low pressure media below 250 psi. This versatility and longevity makes them suitable for plumbing in all types of buildings.
Compared to other threaded-joint fittings, malleable iron versions provide greater mechanical strength through their rigid crystalline iron structure. They can withstand shocks better without fracturing.
Malleable iron fittings enable simple, secure assembly of reliable piping infrastructure through decades of service life. Their compatibility across common pipe materials and applications explains their popularity.
