Black pipe connector is a kind of pipe made of stainless steel plate through cold drawing or hot rolling and other processes. Its surface is not treated with special anti-corrosion treatment, thus presenting a black appearance. Black iron pipe fittings not only have high mechanical strength and abrasion resistance, but also have excellent toughness, plasticity and weldability, making them ideal for a wide range of media transport. The black threaded fittings are used to join black piping together and help provide a seamless flow within malleable iron fittings.
