Malleable iron pipe fittings are malleable cast iron commonly known as malleable iron,which under pouring cast into white cast iron pieces.Then it comes to pipe fittings after malleable annealed.The graphite in the malleable iron pipe fittings shows a mass of flocculent.Its fragmentation effect of matrix is small.So its mechanical properties is higher than gray cast iron with good plasticity and toughness.But malleable cast iron does not carry on the forging processing.The matrix organization of it is different, its performance is different either.The black heart malleable cast iron has high plasticity and toughness,while the pearlitic malleable cast iron has high strength,hardness and abradability.

When steel and malleable cast iron pipe fittings connect by thread, if the working pressure is high(but within 1.6Mpa),steel pipe fittings can be adopted.Steel pipe fittings are made of carbon steel,commonly known as wrought iron pipe fittings.It has good weldable performance and can be used in places where welding is needed.For steel pipe nipple,which are often used to connect to steel equipment such as boilers or water tanks.

Malleable iron pipe fittings mainly include socket bend pipe,900 elbow, 450Y tee,tee,lateral cross,cross,Y reducing tee,reducing cross, coupling,450 elbow,union,plug,bushing,floor drain and so on.
