Malleable Iron pipe fittings, joints and pipe fittings are also called pipe fittings, connectors, joint parts, etc. Joints and pipe fittings are mainly used in various pipeline systems and are used for joints of different pipe fittings. Pipes in various pipeline systems are connected with different joints and pipe fittings to form Pipe steel. Malleable cast iron (male steel) pipe fittings are one type of joint pipe fittings, which can connect different pipe fittings in pipelines so that different pipes can be effectively linked together.
Malleable cast iron (male steel) pipe fittings are made of malleable iron and are connected to the pipes with threads (threads) to ensure good contact and connection with the pipes. The working pressure of this type of pipe fitting is generally 0.1Mpa Within the limit, do not use it under particularly high pressure to prevent some abnormal events. The appearance of malleable iron (male steel) pipe fittings is characterized by thick edges at the ends. To increase the connection strength, it is mainly used for pipe extensions, branches and turns.
Because the graphite in malleable cast iron is in the form of clumps,Small splitting effect on the matrix,Therefore its mechanical properties are higher than gray cast iron,Good plasticity and toughness,However, malleable cast iron cannot be forged and pressed..The matrix structure of malleable cast iron is different,Its performance is also different,Among them, black-core malleable cast iron has high plasticity and toughness.,Pearlitic malleable cast iron has higher strength,Hardness and wear resistance.
