Malleable iron pipe fittings

· Definition and Material

· definitionMalleable cast iron pipe fittings, also known as malleable cast iron pipe fittings, are pipe fittings made of malleable cast iron. They are mainly used for pipes made of steel. They are an important part of the pipeline system and are used to connect, control and protect various pipeline systems2.

· MaterialMalleable cast iron is the common name for malleable cast iron, which is obtained by high-temperature tempering of white cast iron. Malleable cast iron is not steel, but a special kind of iron. Although it is called malleable cast iron, it is not malleable, but it can be cut and processed, and has high mechanical properties, good plasticity and toughness2.

· Features

· Lightweight: The density of malleable cast iron pipe fittings is only half of that of steel, which has obvious advantages in weight. It can effectively reduce the dead weight of the building, reduce the foundation bearing pressure, and save engineering costs.

· High strength: It has high tensile strength and compressive strength, can withstand large loads, and is suitable for various building structures.

· Corrosion resistance：It has good corrosion resistance to a variety of chemicals and can be used for a long time in humid, acidic and alkaline environments, reducing the risk of damage and failure in chemical environments and extending its service life.

· Easy construction：The production and processing process is simple, and it can be installed by welding, threaded connection, etc., which is easy to construct.

· Good thermal conductivity: Can effectively transfer heat, reduce temperature differences inside the building and improve comfort.

· Energy saving and environmental protection: Compared with traditional steel, malleable cast iron pipe fittings consume less energy in the production process and can be recycled, which is in line with the concept of green building.

· Production process2

· White iron casting casting: First, raw materials such as iron ore and scrap steel are smelted through medium frequency electric furnaces and other equipment, and then cast into white cast iron parts.

· Forgeable annealing：The white cast iron parts are subjected to forgeable annealing treatment to decompose the cementite into flocculent graphite, which is a key step to improve the performance of malleable cast iron pipe fittings. During the annealing process, it is necessary to strictly control the process parameters such as heating, high insulation and cooling, low insulation, and air cooling. The smaller the annealing temperature difference, the better, in order to ensure the quality of malleable cast iron pipe fittings.

· Machining: The annealed pipe fittings are machined, such as turning, drilling, tapping, etc. to meet different size and precision requirements.

· Surface treatment: In order to improve the corrosion resistance and aesthetics of malleable cast iron pipe fittings, surface treatment is usually performed, such as hot-dip galvanizing, electro-galvanizing, painting, etc.

· type

· elbow: Used to change the flow direction of the pipeline, there are long elbows, short elbows, equal diameter elbows, reducing elbows, 90 degree elbows, 45 degree elbows, internal and external thread elbows, etc.
