What Are Malleable Iron Pipe Fittings?
Malleable fittings are usually used to connect steel pipes. However, galvanized pipes use galvanized malleable fittings. Malleable iron pipe fittings are most common among malleable fittings, and there are many different types and sizes.
What are malleable fitting?
The malleable fittings refer to those fittings having the property of malleability. This is the physical property of metals, metalloids, or any substance. When a metal is easily deformed, especially when it is not cracked by hammering or rolling, we call it malleable. Malleability is important for forming pressing materials such as metals and plastics.
Malleable iron pipe fittings connect two different pipe components together and guide the movement of gases and liquids. Some malleable pipe fittings are threaded, which means that they have grooves ends that allow the plumber to screw the pipe fitting onto the pipe and allow the plumber to connect different pipes together.
Malleable cast iron is an alloy of iron and carbon, and engineers treat with heat. When it was just cast, there was no graphite in the iron. The carbon content is all in the form of cementite. Malleable cast iron usually contains 2% to 3% carbon, 1% to 2% silicon, 0 to 1% manganese and small amounts of sulfur and phosphorus. Malleable cast iron has high toughness due to its spheroidal graphite and low carbon content. Graphite is formed in such a way that the shape of graphite is not spherical but irregular.
Engineers prefer to use malleable cast iron for parts that need to be cast, perforated or cold formed. Cold forming refers to the process of rolling or pressing thin steel sheets into usable materials. Malleable cast iron is suitable for parts that require the most machinability, which means these parts are easy to machine. It is also suitable for parts that need to withstand low-temperature shocks.
The manufacturer's name or trademark must appear in the malleable fittings.
The buyer shall ensure that the malleable fitting connection includes the service mark specified by the connection.
Material names such as steel, cast steel, malleable iron or ductile iron. This is an extremely important matter and buyers should consider before purchasing malleable pipe fittings.
The buyer shall ensure that the iron undergoes a proper casting process.
