Compared with other cast ferrous metal joints, the machinability of Malleable Iron joint is better than that of cast steel ductile iron, the corrosion resistance is better than that of cast steel, and the heat resistance is better than that of cast steel grey iron.
The shock absorption property is better than that of ductile iron; the low temperature ductile brittle transition temperature is lower than that of ductile iron; the white heart Malleable Iron Steel also has good weldability in the cast iron family.The chemical composition of Malleable Iron joint is low carbon medium silicon and appropriate proportion of manganese and sulfur. Scrap steel can be used as the main raw material, and even scrap iron can be used as the raw material.
The sulfur content of Malleable Iron is relatively higher than that of other cast iron, which is beneficial to the smelting of Malleable Iron in cupola.
Malleable Iron joint has the advantages of low cost, high efficiency, high quality and uniform technology, stable performance and convenient removal of casting pouring riser.Therefore, Malleable Iron Steel industry used to be a large branch of China's foundry industry.
Standard: GB / ANSI /JIS / DIN
temperature tolerance:230℃-250℃
Surface roughness:10μm
After passivation and galvanizing double antirust treatment, the corrosion resistance of Malleable Iron joint is greatly improved and its service life is long, which is far longer than the service life of cast iron fastener.The new type of connection has strong anti stripping ability. When the pipe is deformed, the joint can always be fixed vertically and firmly, eliminating the possibility of steel pipe slipping.
After chemical polishing of Malleable Iron joint, the micro protruding part of the pipe in the chemical medium is preferentially dissolved than the concave part, so as to obtain a smooth surface.The main advantage of this method is that it does not need complex equipment, can polish the workpiece with complex shape, can polish many workpieces at the same time, and has high efficiency.
At the same time, the plastic coating process is adopted, and epoxy resin powder is coated inside the joint.Now two popular methods are painting or rolling. They are sometimes referred to as plastic lined pipe fittings in general.But even if it is painting and rolling, there are essential differences between the two in technology and use effect.
