Joint fittings are also called pipe fittings, connectors, joint parts and so on. Pipes in various piping systems are connected with different joint fittings to form pipe steel.
- Malleable cast iron (steel) fittings are made of malleable cast iron and connected with the pipe by thread (silk buckle). The working pressure is within 0.1Mpa. Its appearance is characterised by the end with a thick edge.
- steel and malleable cast iron fittings steel pipe to threaded connections, if the working pressure is higher (but within 1.6Mpa), steel fittings can be used. Steel fittings made of carbon steel, commonly known as cooked iron fittings. Its weldability is good, can be used in places where welding is required, such as steel pipe hoops are often used as a connection in the boiler or water tank and other steel equipment.
- water supply cast iron pipe fittings processed by grey cast iron casting, water supply cast iron pipe fittings socket type and flange type two kinds of its use and malleable casting pipe is similar to the following types: cross pipe, butyl tube and so on.
The characteristics of cast pipe fittings mainly include the following aspects:
Material diversity: casting fittings joints are made of various materials, commonly cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel and so on. The choice of these materials makes the casting fittings suitable for different working environments and needs1.
Diversified connection methods: the connection methods of casting fittings include direct welding, flange connection, threaded connection and socket connection, etc. Different connection methods are suitable for different working environments and needs. Different connection methods are suitable for different piping systems and working environments, providing greater flexibility and adaptability.
Excellent mechanical properties: for example, ductile iron pipe fittings have the nature of iron and steel performance, excellent mechanical properties, good anti-corrosion properties, good ductility, suitable for municipal industrial and mining enterprises for water supply, gas transmission and so on.
Easy to install: cast pipe fittings are usually well-designed, easy to install, can quickly complete the connection and dismantling of the pipeline, easy to maintain and overhaul.
Strong adaptability: casting fittings can adapt to different working environments and media, such as hot water, steam, etc., and have high tensile and compressive strength, which can eliminate the stress generated by thermal expansion and contraction of the pipeline and protect the equipment and pipeline.
Good sealing performance: casting fittings joints usually have good sealing performance, which can ensure the sealing of piping system and reduce the risk of leakage.
Wide application: casting fittings are widely used in electric power, metallurgy, chemical industry, water supply and drainage and sewage treatment, etc. They are suitable for connecting and repairing all kinds of piping systems.
To sum up, casting fittings joints have a wide range of applications in industrial and municipal engineering due to its material diversity, various connection methods, excellent mechanical properties, easy installation, strong adaptability, good sealing performance and wide range of applications.
