Malleable fittings are usually used to connect steel pipes. However, galvanized malleable fittings are used for galvanized pipe. Malleable iron pipe fittings are most common among malleable fittings and are available in many different types and sizes. Next, the malleable iron pipe fittings manufacturer will share the following content with you.
Malleable fittings are those fittings having the property of malleability. This is a physical property of metals and metalloids, or any kind of matter. We call a metal malleable when it can easily be deformed, especially by hammering or rolling, without cracking the metal. Malleability is important to form pressing materials such as metals and plastics.
Malleable Iron Pipe Fitting
Malleable iron pipe fittings hold two different pipe parts together and direct the gas and liquid movement. Some malleable pipe fittings are threaded, meaning that they have grooved ends that allow plumbers to screw the pipe fittings on the pipes, letting plumbers connect different pipes together
Malleable iron pipe fittings can come in black and galvanized finishes. The three forms of malleable cast iron include whiteheart, blackheart and pearlitic malleable cast iron. The surface zone of the whiteheart malleable cast iron has ferrite. The intermediate zone has temper carbon, ferrite and pearlite. Tempering refers to the hardening of metal. Blackheart malleable cast iron is mostly made of ferrite. The pearlitic malleable cast iron is made from pearlite and other austenite products. Pearlite is made from alternating layers of ferrite and cementite.
Malleable pipe fittings come in a variety of shapes, depending on the applications that the plumber will use the fittings for. These shapes can include the elbow, a fitting that curves to send the pipe in certain direction. Another pipe fitting type, the side outlet elbow, is like the regular elbow, but has an added side outlet.
The tee has three openings, with two on both ends of the pipe and one on one the side. The side outlet tees have four openings, one that is the side outlet. The cross has four openings, with each opening having a corresponding opening on the other side. These different fittings allow the plumber to send pipes in different directions and let pipes feed into each other.
Malleable Iron Pipe Fitting
Malleable iron fittings are made using the most sophisticated metallurgical and processing controls. These fittings are usually made through casting and an automatic precision pattern extrusion. Malleability occurs due to metallic bonding present in most metals. The varieties of free electrons formed during the loss of electrons emerging from the outer-most electron shells of the metal atoms lead to layers of the metal to slide over one another. This process makes the metal malleable.
The manufacturer's name or trademark must be there in the malleable fittings.
The buyer should ensure that the malleable fitting contain service designation for which the fitting is designated.
The material designation like steel, cast, malleable or ductile iron and ASTM No. is an extremely important thing that the buyer should consider before buying malleable pipe fittings.
Buyer's should ensure that the iron is subjected to proper casting processes.
Malleable iron pipe fittings are used in various applications like steam, air, water, gas, oil and other fluids.
